Medical grade silicone tubing is one of the most widely used components in modern healthcare — found in everything from IV infusion sets and ventilator circuits to peristaltic pumps, enteral feeding systems, and surgical drainage assemblies. Global demand runs into billions of meters annually, supplied by hundreds of manufacturers ranging from world-class ISO 13485-certified facilities to unqualified traders relabeling industrial-grade material.
For procurement managers, biomedical engineers, and medical device developers, the challenge is not finding silicone tubing — it is specifying the right tubing and qualifying the right supplier for your specific application, regulatory market, and quality requirements.
Get it right, and you have a reliable, compliant component that performs consistently for the life of your device. Get it wrong, and you face failed biocompatibility testing, regulatory submission delays, pump calibration drift, or — in the worst case — a patient safety incident.
This guide gives you the complete framework for making the right decision.
Before specifying a single dimension, it is essential to understand what "medical grade" actually means — and what it does not.
"Medical grade" is not a regulated term. No regulatory body defines or enforces it. Any manufacturer can label their silicone tubing as "medical grade" without holding a single relevant certification.
What genuinely distinguishes medical grade silicone tubing from standard industrial or food-grade silicone is a combination of:
True medical grade silicone tubing uses platinum-catalyzed addition cure — producing zero chemical by-products. Industrial silicone typically uses peroxide cure, which leaves residual acetophenone, organic acids, and other volatile compounds that can leach into fluid streams or be inhaled.
This distinction is not cosmetic. Residual peroxide by-products are cytotoxic — they will cause cell death in ISO 10993-5 testing. For any application involving patient contact or pharmaceutical fluid transfer, platinum-cured silicone is the only acceptable choice.
For a full technical comparison, see: Platinum-Cured vs. Peroxide-Cured Silicone: Which Should You Choose?
Medical grade tubing must be supported by documented biocompatibility testing — not just a supplier's claim. The minimum acceptable evidence is:
ISO 10993-5 cytotoxicity test report (full report, not just a certificate)
USP Class VI test report (all three in vivo tests passed)
FDA 21 CFR 177.2600 compliance statement
For applications involving prolonged tissue contact, blood contact, or pharmaceutical fluid paths, additional ISO 10993 endpoints are required. See: USP Class VI, ISO 10993, and FDA 21 CFR 177.2600: Which Certification Do You Actually Need?
Medical grade tubing must be manufactured in a cleanroom environment (ISO Class 7 or 8 minimum) under an ISO 13485-certified quality management system with full lot traceability. Industrial silicone tubing is manufactured in standard factory environments with no equivalent controls.
Medical applications typically require tighter dimensional tolerances than industrial applications — ±0.05mm to ±0.10mm on ID and OD, versus ±0.20mm or worse for industrial grades. Dimensional consistency directly affects flow accuracy, device fit, and pump calibration stability.
At Chensheng Medical, "medical grade" means platinum-cured, ISO 13485-manufactured, USP Class VI and ISO 10993-certified, cleanroom-produced silicone tubing — with full documentation to prove it. It is our baseline, not a premium option.
Every silicone tubing specification is defined by five parameters. Understanding each one — and how they interact — is the foundation of correct specification.
The inner diameter is the most functionally critical dimension. It determines:
Flow rate — for a given pressure differential, flow rate scales with the fourth power of ID (Hagen-Poiseuille relationship)
Device compatibility — must match the connector, fitting, or instrument port it connects to
Pump calibration — for peristaltic pump applications, ID is the primary determinant of flow rate per revolution
How to select ID:
Match to the connector or port size your tubing must fit
For fluid transfer applications, calculate required ID from your target flow rate and acceptable pressure drop
For peristaltic pump applications, refer to the pump manufacturer's tubing specification
Available range at Chensheng Medical: 0.25mm to 50mm ID (custom sizes available)
The outer diameter determines:
Fit in pump heads — for peristaltic applications, OD must match the pump head channel
Connector retention — barbed fittings grip the OD; too large or too small causes leakage or pull-off
Routing and clearance — in device assemblies, OD determines space requirements
Relationship to ID and wall thickness:
OD=ID+(2×Wall Thickness)OD=ID+(2×Wall Thickness)
When specifying tubing, you need to define any two of the three dimensions (ID, OD, wall thickness) — the third is derived.
Wall thickness is the most influential dimension for mechanical performance:
Wall Thickness Effect | Thinner Wall | Thicker Wall |
Flexibility | More flexible | Stiffer |
Kink resistance | Lower | Higher |
Pressure rating | Lower | Higher |
Compression set recovery | Faster recovery | Slower recovery |
Circuit compliance | Higher (more expansion) | Lower (less expansion) |
Weight | Lighter | Heavier |
Cost | Lower | Higher |
General guidance by application:
Application | Typical Wall Thickness |
Peristaltic pump tubing | 1.0–2.0mm (optimized for compression recovery) |
IV / fluid transfer tubing | 1.0–1.5mm |
Respiratory circuit tubing | 1.5–3.0mm (kink resistance priority) |
Drainage tubing | 1.5–2.5mm |
High-pressure applications | 2.5–5.0mm+ |
Neonatal / micro-bore tubing | 0.5–1.0mm |
Shore A hardness measures the resistance of the silicone to indentation — essentially, how soft or stiff the material feels. It is measured per ASTM D2240 using a standardized indenter under a defined load.
Medical silicone tubing is available from Shore A 10 (very soft, gel-like) to Shore A 80 (firm, rubber-like). The optimal hardness depends on your application:
Shore A Range | Feel | Typical Medical Applications |
10–20 | Extremely soft, gel-like | Soft tissue contact, neonatal applications, implant-adjacent |
20–35 | Very soft, highly flexible | Neonatal tubing, soft drainage, gentle patient contact |
35–50 | Soft, flexible | General fluid transfer, IV tubing, feeding tubes |
50–65 | Medium, resilient | Peristaltic pump tubing, respiratory circuits, standard medical tubing |
65–80 | Firm, stiff | High-pressure tubing, structural components, gaskets |
Critical interaction: hardness and wall thickness together determine flexibility. A thin-wall tube in Shore A 60 may be more flexible than a thick-wall tube in Shore A 30. Always consider both parameters together.
For a comprehensive guide to Shore A hardness selection across all medical applications, see our dedicated article: Silicone Shore A Hardness Explained: How to Select the Right Durometer for Your Medical Application
Tolerance defines the acceptable variation range around the nominal dimension. For medical applications, tolerance directly affects:
Flow accuracy — ID variation causes flow rate variation in pump applications
Device fit — OD variation affects connector retention and leak-tightness
Regulatory compliance — some standards specify maximum dimensional variation
Standard tolerance grades for medical silicone tubing:
Grade | ID Tolerance | OD Tolerance | WT Tolerance | Typical Application |
Standard | ±0.20mm | ±0.20mm | ±0.15mm | General fluid transfer, non-critical applications |
Medical | ±0.10mm | ±0.10mm | ±0.10mm | Standard medical device applications |
Precision | ±0.05mm | ±0.05mm | ±0.05mm | Peristaltic pump, neonatal, pharmaceutical |
Ultra-precision | ±0.025mm | ±0.025mm | ±0.025mm | Micro-bore, analytical, specialty applications |
Tighter tolerances cost more — not because of material cost, but because of the process controls required (closed-loop laser micrometer monitoring, tighter extrusion parameter control, higher rejection rate). Specify the tolerance your application actually requires — not the tightest available.
Use this section to identify the correct specification starting point for your application, then refine based on your specific requirements.

Silicone tubing's compatibility with the fluid it carries is a critical selection criterion that is frequently under-specified. Platinum-cured silicone has excellent compatibility with most aqueous and biological fluids, but significant limitations with organic solvents.
Fluid / Chemical | Compatibility | Notes |
Water, saline, buffer solutions | ✅ Excellent | No swelling or degradation |
Aqueous drug solutions (most) | ✅ Excellent | Verify E&L for specific APIs |
Ethanol / IPA (dilute, <50%) | ✅ Good | Minor swelling at high concentrations |
Ethanol / IPA (concentrated, >70%) | ⚠️ Moderate | Measurable swelling; verify dimensional stability |
Dilute acids (pH 2–6) | ✅ Good | Concentrated HF and H₃PO₄ attack silicone |
Dilute bases (pH 8–12) | ✅ Good | Concentrated NaOH causes surface degradation |
Blood and blood products | ✅ Good | Verify ISO 10993-4 hemocompatibility for blood-contact devices |
Cell culture media | ✅ Excellent | Low extractables critical for cell viability |
Oils and lipids | ⚠️ Moderate | Some swelling; verify for specific oil type |
Aromatic solvents (toluene, xylene) | ❌ Incompatible | Significant swelling — use fluoropolymer tubing |
Chlorinated solvents (DCM, CHCl₃) | ❌ Incompatible | Significant swelling — use fluoropolymer tubing |
Concentrated oxidizing acids | ❌ Incompatible | Use PTFE |
Steam / hot water (to 134°C) | ✅ Excellent | Autoclave compatible |
Silicone oils | ⚠️ Variable | May cause swelling; verify for specific grade |
For pharmaceutical applications: Chemical compatibility data from generic silicone datasheets is not sufficient for drug contact qualification. Always conduct application-specific extractables and leachables testing with your actual drug formulation and contact conditions.
Your sterilization method must be confirmed compatible with the tubing before finalizing specification. Platinum-cured silicone is broadly compatible with all major sterilization methods:
Method | Compatibility | Key Considerations |
Autoclave 121°C | ✅ Excellent | Multiple cycles; no dimensional change |
Autoclave 134°C | ✅ Excellent | Prion protocols; full property retention |
EtO (ethylene oxide) | ✅ Excellent | Verify residuals per ISO 10993-7 |
Gamma irradiation (25–50 kGy) | ✅ Good | Minor yellowing possible; properties maintained |
E-beam | ✅ Good | Similar to gamma; faster cycle |
H₂O₂ plasma (VHP) | ✅ Good | Low-temperature option for heat-sensitive assemblies |
Peracetic acid | ✅ Good | Verify concentration and contact time |
Dry heat (180°C) | ✅ Excellent | Silicone withstands dry heat sterilization |

The intended use pattern — single-use or reusable — has significant implications for tubing specification:
Factor | Single-Use | Reusable |
Wall thickness | Thinner (lower cost, lighter weight) | Thicker (withstands repeated sterilization) |
Shore A hardness | Optimized for single-use performance | Optimized for durability over multiple cycles |
Sterilization | EtO or gamma (supplied sterile) | Autoclave (reprocessed by user) |
Packaging | Individual sterile pouch | Bulk coil or multi-pack |
Regulatory pathway | Single-use labeling required; cannot be reprocessed | Reprocessing instructions required |
Autoclave cycle rating | Not required | Minimum 50 cycles; typically 100+ |
Cost per use | Higher unit cost; lower total cost (no reprocessing) | Lower unit cost; higher total cost (reprocessing labor + validation) |
Infection control | Eliminates cross-contamination risk | Requires validated reprocessing protocol |
Regulatory note: Single-use labeling ("For single use only" / "Do not reuse") carries a regulatory obligation — the manufacturer must be able to demonstrate that the device is not designed or validated for reuse. If your device is labeled single-use, ensure your tubing specification and packaging support this claim.
A supplier's Technical Data Sheet (TDS) is your primary reference for material properties. Here is how to interpret the key parameters:
Parameter | What It Tells You | What to Watch For |
Curing system | Platinum or peroxide | Insist on platinum for medical applications |
Shore A hardness | Material stiffness | Verify it matches your application requirement |
Tensile strength (MPa) | Resistance to tearing | Minimum 7 MPa for medical pump tubing |
Elongation at break (%) | Flexibility and fatigue resistance | Minimum 400% for dynamic applications |
Tear resistance (kN/m) | Resistance to crack propagation | Minimum 25 kN/m for pump tubing |
Compression set (%) | Elastic recovery after compression | Maximum 10% for pump tubing |
Temperature range (°C) | Operating and sterilization limits | Confirm covers your sterilization method |
Specific gravity | Material density | Used for weight calculations; ~1.1–1.2 for silicone |
Certifications listed | Compliance claims | Always request the underlying test reports |
Critical warning: A TDS lists typical or nominal values for the compound — not lot-specific values. Always request a lot-specific Certificate of Analysis (CoA) for each production lot you receive, confirming actual measured values for critical parameters.
Before placing an order with any medical silicone tubing supplier, get clear answers to these ten questions:
1. What curing system do you use — platinum or peroxide?Correct answer for medical applications: platinum-catalyzed addition cure. Ask for written confirmation on the TDS.
2. Can you provide the full ISO 10993-5 cytotoxicity test report — not just the certificate?The report should show actual cell viability data, the specific compound tested, the testing laboratory, and the test date.
3. Is your ISO 13485 certificate current, and does its scope cover this specific product?Verify the certificate against the issuing body's registry. Check that the scope explicitly covers medical silicone tubing.
4. Can you provide lot-level traceability from raw material to finished product?A qualified manufacturer can trace any finished lot back to the specific raw material batch.
5. What is your cleanroom classification for medical product manufacturing?ISO Class 7 or 8 is the minimum for medical silicone tubing. Ask for environmental monitoring records.
6. What dimensional monitoring do you use during extrusion?Closed-loop laser micrometer is the standard for precision medical tubing. Manual spot-checking is insufficient for ±0.05mm tolerance.
7. What is your change control procedure — and will you notify us before changing raw material suppliers or process parameters?A qualified supplier has a formal change control procedure and commits to customer notification before any change affecting form, fit, function, or regulatory documentation.
8. Can I conduct a factory audit — on-site or remote?Any qualified medical silicone manufacturer will welcome audits. Resistance to auditing is a significant red flag.
9. What is your CAPA process for quality escapes that reach the customer?Look for a formal, documented CAPA procedure under ISO 13485 — not just "we'll replace it."
10. Can you provide the complete documentation package needed for my regulatory submission (510(k) / CE / NMPA)?A qualified supplier understands what documentation device manufacturers need and has it ready.

All tubing is manufactured from platinum-cured silicone compound in our ISO Class 7 cleanroom under our ISO 13485 quality management system.
Q1: What is the difference between medical grade, food grade, and industrial grade silicone tubing?
A: Medical grade silicone tubing is manufactured from platinum-cured compounds in a cleanroom environment under ISO 13485 quality management, with documented biocompatibility testing (ISO 10993, USP Class VI) and full lot traceability. Food grade silicone meets FDA 21 CFR 177.2600 for food contact but is not manufactured under ISO 13485 and may not have full biocompatibility documentation. Industrial grade silicone typically uses peroxide-cured compounds with no biocompatibility testing and no cleanroom manufacturing. Only medical grade silicone is appropriate for patient-contact or pharmaceutical fluid-contact applications.
Q2: Can I use the same silicone tubing specification for both single-use and reusable applications?
A: Not typically. Single-use and reusable applications have different wall thickness, Shore A hardness, and sterilization requirements. Using a single-use specification for reusable applications may result in premature failure after repeated autoclave cycles. Using a reusable specification for single-use applications adds unnecessary cost and weight. We recommend specifying separately for each use pattern and can advise on the optimal specification for each.
Q3: How do I know if a silicone tubing supplier is genuinely ISO 13485 certified?
A: Request a copy of the ISO 13485 certificate and verify it against the issuing notified body's online registry (BSI, TÜV, SGS, Bureau Veritas, etc.). Check that: (1) the certificate is current and not expired; (2) the scope explicitly covers medical silicone tubing or medical device manufacturing; (3) the company name and address on the certificate match the supplier you are dealing with. A certificate image alone is not sufficient — always verify against the issuing body's database.
Q4: What is the minimum order quantity for medical grade silicone tubing from Chensheng Medical?
A: For standard catalog sizes, samples are available from as little as 1–5 meters for initial qualification testing. Production orders are priced per meter with volume pricing from 100m, 500m, and 1,000m+. For custom sizes requiring new extrusion tooling, minimum order quantities depend on the tooling investment — typically 50–200m for the initial order. Contact our team for a specific quotation based on your size and volume requirements.
Q5: How long does it take to receive samples for qualification testing?
A: For standard catalog sizes available in stock, samples can be dispatched within 1–2 business days by international express courier (DHL, FedEx, UPS). For custom sizes requiring new extrusion tooling, the typical timeline is 7–10 business days from drawing confirmation to sample shipment. Full documentation (TDS, CoA, ISO 10993 reports, USP Class VI reports) is provided with all samples.
Q6: Can you provide silicone tubing that is already sterilized and ready for use?
A: Yes. We offer EtO-sterilized silicone tubing in individual sterile peel-open pouches, and gamma-sterilized tubing for applications where EtO is not preferred. Sterile tubing is produced in our ISO Class 7 cleanroom and packaged under cleanroom conditions before sterilization. Sterilization validation certificates and EtO residual test reports (per ISO 10993-7) are provided with sterile product. Lead time for sterile tubing is typically 3–4 weeks from order confirmation.
Q7: We are switching from a current supplier. How do we qualify Chensheng Medical tubing as a drop-in replacement?
A: We recommend a structured qualification protocol: (1) request samples matched to your current specification; (2) conduct dimensional verification, Shore A hardness check, and visual inspection; (3) perform functional testing in your device or application; (4) conduct sterilization compatibility testing with your actual protocol; (5) review our documentation package against your regulatory submission requirements. For regulated devices, a formal change control process and re-qualification testing will be required before switching suppliers in production. Our applications engineering team can support you through this process.
Q8: Do you offer volume pricing, and what are the price breaks?
A: Yes. Volume pricing is available for all standard and custom silicone tubing. Typical price break points are at 100m, 500m, 1,000m, 5,000m, and 10,000m+. For annual volume agreements, we can offer fixed pricing with guaranteed supply allocation. Contact our commercial team with your annual volume estimate for a specific quotation. We are transparent about pricing and will provide a detailed quotation within 24 hours of receiving your specification.
