Waterlock/Muffler NLP40 Dual-Stage Rotating Inlet/Outlet for 40 mm Hose 4.5 L Capacity

Our NLP waterlocks are of dual stage construction featuring upper and lower chambers with a horizontal partition plate and a riser tube through the centre. The installation of the exhaust system, even in confined engine spaces, is greatly simplified due to the 360º rotating top chamber and both in- and outlet connectors. For optimum silencing of exhaust noise you can also use a VETUS muffler and gooseneck, after the waterlock.
