Leyland Hose & Silicone supply Marine and Silicone Wet Exhaust Hoses for engine and auxiliary generator systems, used in many of today’s modern, in-board engine pleasure boats.

Manufactured from only the highest quality silicones and reinforcement fabrics, the are designed to operate at temperatures up to +180°C. Our ‘HT’ (High Temperature) Wet Exhaust and Turbo hoses, will operate at temperatures up to 210°C.

They are offered in a range of straight, single hump, double hump and elbow configurations. We also offer EPDM, wire reinforced, wet exhaust hose in a range of diameters and up to 2m long. These are suitable for lower temperatures up to 130°C and will operate at significantly higher positive pressures or, under negative pressure caused by suction.

Leyland Hose and Silicone Marine Wet Exhaust Hoses are tested and meet the requirements of SAE J2006 R3. Our EPDM hose meets the requirements of SAE J2006 R2.


LHSS silicone hoses are specifically designed for use in the wet exhaust systems, used on in-board marine engines and generators.
