Silicone heater or coolant house. Due to our super strong multi ply construction the smaller diameter hoses can often bend and flex in multiple directions. Note, as the diameter increases the ability to bend the hose also decreases.

Silicone hose is a extremely flexible compared to rubber, with the ability to maintain this flexibility over the lifespan of its use. Under some conditions rubber hoses are at risk of splitting, hardening, or dry rot, which is why silicone hoses are the choice for many trucks, buses, performance cars, and many other vehicle and industrial applications.

We increase the number of plys and wall thickness of our 1 metre silicone hoses as the diameter increases, this is because we want all our range capable of carrying fluid and air at very high pressures. So if you’re building a racing vehicle, adding turbochargers or superchargers, our silicone hose is the way to go.
