NLP HD Heavy Duty Waterlocks for Marine Engines

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 90mm exhaust system.

Features :

Capacity (liters): 10.

Length (mm): 515.

Width (mm): 210.

Height (mm): 362.

Airlock position: Vertical.

% Noise Reduction: 35.
