Vetus LSS45A - Waterlock LSS45 for Ø 45 mm Hose with Rotating Inlet and Outlet

Vetus LSS45A Waterlock for 45 mm Exhaust Hose, Rotating Inlet and Outlet, 5.7 L Capacity

The Vetus LSS45A is a robust marine waterlock engineered for vessels operating in rough waters or equipped with extended exhaust lines. Designed for hoses with a 45 mm internal diameter, this model offers a 5.7 litre capacity to prevent the substantial volume of cooling water in the exhaust system from running back into the engine when it is shut down. Its inlet and outlet stubs rotate through 360 degrees, providing exceptional installation flexibility in confined or complex engine compartment layouts. With a reduced height of 225 mm, the LSS45A can be installed below flooring structures, making it highly suitable for sailing yachts and boats with limited vertical space. A drain plug is integrated for winter storage, and one securing strap is included as standard.
