VETUS NLP40 Waterlock 40mm 4.5L – Dual-Stage Marine Exhaust Waterlock

VETUS NLP40 Waterlock 40mm

The VETUS NLP40 Waterlock 40mm is a dual-stage marine exhaust waterlock and muffler designed for wet exhaust systems on boats and yachts. With a 4.5 litre capacity and 40 mm exhaust hose connections, the VETUS NLP40 helps reduce exhaust noise while minimizing back pressure in the marine exhaust system. Its 360° rotatable top chamber and rotating inlet and outlet connections provide flexible installation options, particularly where engine-room space is limited.

The VETUS NLP40 waterlock is suitable for compatible marine diesel engines, yacht exhaust systems, boat exhaust installations, and wet exhaust applications. It combines waterlock and muffler functions in a compact design, making it a practical component for marine engine exhaust systems.

VETUS NLP40 Dual-Stage Waterlock

The VETUS NLP40 dual-stage waterlock features separate upper and lower chambers divided by a horizontal partition, with a riser tube through the centre. This dual-stage construction is designed to provide effective exhaust noise reduction while maintaining low back pressure.

A waterlock is an important component in a water-injected marine exhaust system. It helps collect water that may remain in the exhaust after the engine has stopped, helping reduce the risk of water flowing back toward the engine. VETUS explains that its waterlocks also provide sound insulation within wet exhaust systems.

40mm Marine Exhaust Waterlock

The VETUS NLP40 40mm waterlock is designed for exhaust hose with an internal diameter of 40 mm (1 9/16″) and has a 4.5 litre (1.19 U.S. gallon) capacity.

The rotating connections make it easier to position the exhaust hose according to the available installation space. This can be particularly useful in compact yacht engine rooms and boat engine compartments where conventional fixed connections can make installation more difficult.

VETUS Marine Exhaust Waterlock for Boats and Yachts

The VETUS NLP40 marine exhaust waterlock is suitable for a wide range of compatible marine exhaust applications. It can be used on boats, yachts, sailboats, motor yachts and other vessels equipped with water-injected wet exhaust systems.

The supplied mounting brackets allow the waterlock to be secured to a bulkhead or floor, while the securing straps help provide additional installation support.

For additional exhaust noise reduction, VETUS recommends that a compatible muffler and gooseneck can be used after the waterlock as part of the overall exhaust arrangement.
