HPS 4-Ply Silicone Coupler Hose

The HPS HTST-350-BLUE is a high-temperature, 4-ply reinforced silicone tube coupler hose engineered to meet or exceed SAEJ20 industry standards. Its construction utilizes premium polyester fabric embedded in high-temperature silicone rubber, making it suitable for extreme temperature and pressure environments. This hose is ideal for joining two hard pipes, reducing the risk of connections separating or causing damage to hard pipes or equipment. With an inside diameter of 3-1/2 inches and a length of 12 inches, this blue silicone hose can withstand a maximum pressure of 40 PSI. It operates effectively within a wide temperature range, from -65°F to +350°F (-177°C). The hose is compatible with water and anti-freeze solutions like coolant, making it suitable for cooling system applications. However, it is explicitly not compatible with fuel or oil. Professionals in various industries rely on HPS silicone hoses, including high-performance racing, commercial trucking, marine, agricultural, and general manufacturing. Its durability and flexibility also make it a good choice for custom turbo or intercooler piping fabrication and other DIY projects.
