The Vetus NLP50HD is a marine exhaust waterlock made from a composite that is heat resistant to temperatures of up to 260°C. Due to the design of the waterlock, it also acts as an exhaust sound muffler, offering superior sound reduction. This waterlock features a dual stage functionality, consisting of one lower chamber and one upper chamber. Coolant water and exhaust gas enter the inlet in the bottom chamber, travel up through the central riser tube and then exit through the outlet in the top chamber. The design prevents water flowing back down the exhaust line to the engine when it is switched off.

Installation of the Vetus waterlock is easy and flexible, due to the compact and clever design. The upper chamber can rotate through 360° to correctly position inlet and outlet ports to suit your application. The hose connections can also be rotated through 360° for a fully customised installation. This makes installation simple even in the most confined engine rooms. The waterlock also features a floor mounting bracket and wall mounting straps supplied as standard, as well as drain plugs for winter storage.
