What temperature range can this fluorine rubber heat shrink tubing withstand?
This tubing operates reliably from -55°C to 200°C, with short-term exposure tolerance up to 220°C. Shrinkage begins at 150°C and is fully completed at 175°C, making it suitable for demanding high-temperature environments such as engine compartments and industrial systems.
Q2
What is the shrink ratio of this heat shrink tubing?
The tubing features a 2:1 shrink ratio, meaning it will radially shrink by 50% when heat is applied. Axial (lengthwise) shrinkage is controlled to less than 20%, ensuring reliable coverage and fit without excessive length reduction.
Q3
Is this tubing resistant to fuels and chemical solvents?
Yes. The fluorine rubber material provides excellent resistance to fuel, lubricating oil, hydraulic fluid, and a wide range of organic solvents. This makes it an ideal choice for use in engine compartments, fuel tanks, hydraulic systems, and other chemically harsh environments.

Q5
How should this heat shrink tubing be properly installed?
Slide the tubing over the component requiring protection, ensuring full coverage. Apply heat using a heat gun or oven at approximately 175°C until the tubing is fully shrunk and conforms to the component. After cooling, inspect to verify sealing and insulation integrity. Avoid excessive heating to prevent material degradation.
Q6
What are the recommended storage conditions and packaging details?
The tubing is packaged in coiled or straight-cut form, 50 meters per roll, sealed in moisture-proof bags. Recommended storage conditions are -20°C to 30°C with relative humidity below 70%. Avoid prolonged UV exposure to maintain material properties and shelf life.
