It can be installed above or below the waterline and is suitable for petrol (gas) or diesel applications. It has better sound absorbing properties of 22-28 dB depending on the engine it is being used with.
The range of exhaust waterlocks are made from heat resistant GRP (glass reinforced plastic) along with the rest of their wet exhaust system components. Because of this construction, the waterlocks are corrosion resistant and can withstand heat up to 177°C (350°F).
The Water lock is only suitable for use in wet exhaust systems and should be used with approved rubber marine exhaust hose.
