15x21mm
Custom
Product Description
For applications where failure is not an option, our 15x21mm heavy-duty silicone hose delivers uncompromising performance. Featuring a substantial 3mm thick wall, this hose is engineered for maximum resilience against pressure, vacuum, and physical stress. It is the definitive choice for critical industrial, automotive, and laboratory systems that demand the utmost in reliability and longevity.
Extreme Durability & Pressure Resistance: The formidable 3mm wall provides exceptional structural integrity, enabling it to handle significantly higher working pressures and resist expansion compared to standard tubing.
Superior Vacuum Rating: Unlike thinner tubes that collapse under negative pressure, this hose’s rigid construction makes it ideal for vacuum lines, degassing applications, and suction systems.
Virtually Kink-Proof: The thick, semi-rigid profile ensures the flow path remains open and unrestricted, even in installations with gradual bends. It holds its shape under stress, guaranteeing consistent performance.
Enhanced Abrasion & Tear Resistance: Built to survive harsh industrial environments, this hose withstands physical impacts, abrasion, and tearing, making it perfect for exposed routing and dynamic applications.
Industrial-Grade Purity: Despite its toughness, it is manufactured from 100% platinum-cured silicone. It meets FDA and LFGB standards, ensuring a pure, non-toxic fluid path for sensitive media even in demanding conditions.

The ultimate solution for the most demanding tasks:
Industrial Machinery & Equipment: Perfect for high-pressure coolant lines, robust fluid transfer in manufacturing plants, and pneumatic control lines in heavy-duty equipment.
Vacuum Systems & Pumps: The ideal choice for connecting vacuum pumps, running vacuum manifolds, and for use in scientific vacuum chambers where outgassing must be minimal.
Automotive & Marine Performance: Excellent for durable coolant transfer, boost control lines, and other under-hood applications requiring high heat and pressure resistance.
Heavy-Duty Protective Jacketing: Use it as an ultra-tough outer conduit to protect sensitive cables, wires, or smaller hoses from crushing, impact, and abrasion in high-traffic areas.
Pressurized Fluid & Chemical Transfer: Reliably transports a wide range of chemicals and fluids under elevated pressure where unreinforced hoses are specified.
