Waterlocks NLP – MG series

The NLP waterlocks are of dual stage construction, featuring upper and lower chambers with a horizontal partition plate and a riser tube through the centre. These NLP waterlocks offer superior silencing of exhaust noise with minimal back pressure. Since the top chamber may be rotated through 360° and both the inlet and the outlet connectors can rotate through 360°, installation of the exhaust assembly even in confined engine spaces is greatly simplified. The mounting brackets enable these waterlocks to be either bulkhead or floor mounted.

VETUS Heavy Duty Composite

The VETUS NLP series waterlocks are made from a specially blended composite that is heat resistant up to 260°C. While the NLP waterlock design is already well known for its silencing features, versatile installation options, and extremely low backpressure, it now adds mechanical properties that can meet any challenge and puts it in a unique position in the market! Thermal resistance to deformation under pressure is 250°C; almost double that of standard GRP materials. The same goes for tensile and flexural strength! For those concerned by weight, there is good news as well. All these benefits are available at almost half the weight of the competition!
