DUAL STAGE WATERLOCKS

Type NLP
Superior silencing, minimal back pressure
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 rotating inlet and outlet connectors. For optimum silencing of exhaust noise you can also use a VETUS
muffler and gooseneck, after the waterlock.
