LHSS manufacture silicone hoses designed to connect metal pipe work and components, in systems using water and ethylene glycol based coolants.Manufactured from only the highest quality materials and reinforcement fabrics, our silicone hoses are designed to operate at temperatures from - 50°C up to +180°C and at operating pressures of 2.5 – 4 bar.

LHSS can meet specific requirements for any silicone hose, operating at pressures in excess of 6 bar, easily exceeding the demands of modern Euro 6 engines. We offer superior reliability and out perform conventional materials such as EPDM. Operating at a wider temperature range, LHSS products retain flexibility at -50°C and maintain physical properties beyond the temperature limits tolerated by conventional silicone hose materials.


Applications of Silicone Hoses

LHSS silicone hoses are specifically designed for use in coolant systems on trucks, buses, passenger cars, generators, railway engines and many other vehicle and industrial applications where connections are required between rigid or flexible metal pipes. They are ideal for joining pipes of similar or differing diameters – reducers. Available in standard sizes from 6mm to 152mm diameter, with diameters greater than 152mm made to specific customer requirements. We meet or exceed the requirements of SAE J20 R1 Class A. OAT (Organic acid based coolants) are resistant to OAT (Organic acid based coolants) please see our range of OAT hoses.
