Waterlock/muffler with dual stage construction. Superior silencing of exhaust noise with minimal back pressure. 360° rotatable top chamber and connectors
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 inlet and outlet connectors. For optimum silencing of exhaust noise you can also use a VETUS muffler and gooseneck, after the waterlock. Type NLP50 has an exhaust hose with an inside diameter of 51mm and a capacity of 4.5 litres. Comes with two securing strapsand includes mounting brackets for bulkhead or floor mounting.
