This tubing operates reliably from -55°C to 200°C, with short-term exposure tolerance up to 220°C. The shrinkage process begins at 150°C and completes at 175°C, making it suitable for high-heat industrial and automotive environments.
The product features a 2:1 shrink ratio, meaning it shrinks radially by 50% while the axial shrinkage remains under 20%. This ensures a snug, conformal fit over a wide variety of component shapes and sizes.
Yes. The tubing fully complies with ROHS, REACH, and Sony SS-00259 environmental directives. It is free from halogens, PBDEs, and other hazardous substances. It is also UL94 V-0 flame retardant rated, self-extinguishing within 15 seconds.
Made from fluorine rubber, this tubing resists fuel, lubricating oil, hydraulic fluid, and a wide range of organic solvents. It is specifically designed for demanding applications such as engine compartments, fuel tanks, and hydraulic systems.
Slide the tubing over the component ensuring full coverage, then apply heat using a heat gun or oven at 175°C until the tubing is fully shrunk and conforms to the component. After cooling, verify that sealing and insulation integrity are maintained.
The tubing is available coiled or straight-cut, packaged in 50-meter rolls sealed in moisture-proof bags. For optimal storage, keep at temperatures between -20°C and 30°C with relative humidity below 70%, and avoid prolonged UV exposure.
