Vetus Plastic Waterlock Type Muffler NLP90 for Inner Diameter Hose of 3 9/16"
The latest generation of Vetus waterlocks, type NLP are amde of injection-moulded
plasitc materials, making them lightweight, durable and corrosion proof. These
NLP waterlocks are of dual stage construction, featuring upper and lower
chambers with a horizontal partition plate and a riser tube through the centre.
Compared with single stage waterlocks using only one chamber, 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.
How it works
The rotatable inlet of the waterlock is connected to the engine exhaust
manifold, using Vetus exhaust hose. The exhaust gases, mixed with cooling water
are forced from the lower chamber into the upper one, via the central riser tube
and the through the outlet connector at the top. This outlet connector is
coupled to the transom connector, again by means of Vetus exhaust hose.
