Made from specially blended NAVIDURIN® composite, which is heat resistant up to 260°C.

While the NLP airlock design is already well known for its soundproofing characteristics, versatile installation options and extremely low back pressure, it now adds mechanical properties capable of meeting any challenge and placing it in a unique position on the market.

The thermal resistance to deformation under pressure is 250°C, almost double that of standard GRP materials, while the tensile and flexural strength are the same. What's more, all these advantages are available at a weight almost half that of the competition.

Features a 360° rotating body and endless connection options. Comes with floor and bulkhead mounting brackets and drain plugs for winter storage.

Suitable for 45mm exhaust system.

Waterlock designed for modern high performance boats with one or two large engines that have limited space in the engine room.

The outlet connection at the top can be rotated 360º and the inlet connection is at a 45º upward angle. The MG type can only be installed in water-injected exhaust systems. Its body is made entirely of synthetic materials, therefore insensitive to corrosion or galvanic action.

To optimize noise reduction, flexible supports for MG and HPW watercoks can be used.

High silence, minimal back pressure

Our NLP waterlocks feature a two-stage design with upper and lower chambers featuring a horizontal separator plate and a rising tube through the center. Exhaust system installation, even in confined engine spaces, is greatly simplified thanks to the 360° rotating chamber and inlet and outlet connectors. For optimal exhaust noise silencing, you can also use a VETUS silencer and gooseneck after the waterlock.
