The HPS High Temp 3-ply Fluorolined Reinforced Silicone Breather and Bypass Valve Hose Kit is designed to replace stock OEM rubber breather and bypass valve hoses which weaken and fail over time. Made with premium quality materials, this silicone hose kit can withstand harsh high temperature and high pressure operating conditions. The hoses are fluorolined to allow for prolonged exposure to oil and fuel. HPS silicone hose kits have all the correct bends and dimensions for a well-fit replacement of worn out and damaged OEM rubber hoses. Compared to the universal hoses from the local auto store, HPS silicone hose kits are much easier to work with. Maximum temperature rating: 350 degrees Fahrenheit. 100% stainless steel embossed hose clamps are included for easy installation.
