Product Description
When standard tubing fails and heavy-duty is not enough, our 21x27mm Fortress-Wall silicone tubing provides the answer. With an immense 3mm wall thickness, this is the most robust and structurally sound non-reinforced tube in our portfolio. It is engineered not just as a conduit, but as a structural component designed to withstand extreme compressive forces, severe impacts, and the most punishing industrial environments imaginable.
Absolute Crush-Proof Integrity: The 3mm solid wall offers phenomenal resistance to compression, flattening, and deformation, maintaining its profile under extreme point loads and external pressure.
Maximum Pressure & Vacuum Stability: Provides a highly stable conduit for systems with significant pressure spikes or deep, continuous vacuum, completely eliminating the risk of collapse or expansion.
Fortress-Level Physical Protection: Acts as a formidable protective armor for critical components. Its sheer mass and toughness provide unparalleled defense against abrasion, cutting, and blunt force impact.
Vibration & Harmonic Dampening: The substantial wall thickness naturally absorbs and dampens mechanical vibrations, helping to quiet noisy systems and protect sensitive internal components from harmonic stress.
Certified Purity, Unyielding Strength: Manufactured from 100% platinum-cured silicone, it complies with FDA and LFGB standards, offering a chemically inert and non-toxic solution for applications where both strength and purity are paramount.

Designed for applications that transcend conventional tubing use:
Structural Spacers & Bumpers: Ideal for use as non-conductive, temperature-resistant spacers, isolators, and impact bumpers in machinery and electronic assemblies.
Industrial Robotics & Cable Carriers: Provides the ultimate protective pathway for cabling in robotic arms and automated systems, resisting crushing, abrasion, and constant motion stress.
High-Stress Pneumatic & Hydraulic Jacketing: Encapsulates and protects high-pressure lines from external damage, adding a critical layer of safety and durability in aggressive environments.
Mining & Construction Equipment: Protects wiring and fluid lines on heavy equipment exposed to rock strikes, extreme weather, and constant vibration.
High-Force Peristaltic Pump Systems: The ultra-rigid wall withstands the highest roller compression forces without fatigue, ensuring long life and consistent flow rates with abrasive or viscous media.

Performance Advisory: This is our most rigid and robust non-reinforced tube. Its primary feature is structural strength, not flexibility. It is intended for straight-run applications or those with very large, gentle bends.
Selection Guide: This 3mm wall tube offers maximum structural integrity and crush resistance. For extreme durability with some workability, consider our 2.5mm wall version. For a heavy-duty balance of strength and flexibility, our 2mm wall tube is an excellent choice.
