Our straight reducers enable you to join 2 outlets of different diameter or to reduce the overall ID of pipe work. Silicone Hose is reinforced with textile layers to be extreme pressure resistant and also to vacuums in your Air Charge System. These Hoses are suitable for your Intercooler system, Intake system, Water lines or similar. 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 straight reducers 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.
