NLP Waterlock Mufflers both silence engine noise, and collect the cooling water present in the exhaust hose when the engine is stopped, preventing drainage back into the engine. The dual stage construction of the NLP features separate upper and lower chambers. Compared with single stage waterlocks with only one chamber, such as the Vetus LP muffler, the NLP offers superior noise reduction with minimal back pressure.
Both inlet and outlet connectors, as well as the entire upper chamber, rotate a full 360 to greatly simplify installation - especially in confined spaces
Synthetic material - lightweight, durable, and completely corrosion-proof
Both chambers have drain plugs for winter storage
Supplied with securing straps
For 2" hose, the larger NLP50S is suitable for longer exhaust runs compared to the NLP50
40mm Vetus hose for the NLP40 is available - see our Order# 156482
