Vetus WLOCKL50S Super Waterlock for 50 mm Exhaust Hose, Fixed Connections, 10.5 L Capacity
The Vetus WLOCKL50S is a large-volume marine waterlock designed for exhaust systems using hoses with a 50 mm internal diameter. With a generous 10.5 litre internal capacity, this model is recommended for installations where the total exhaust hose length does not exceed 4 metres. The waterlock effectively collects cooling water present in the exhaust system when the engine is shut down and significantly reduces noise due to its sound-deadening internal construction. Fixed inlet and outlet connections provide a secure, reliable interface, while a built-in drain plug allows complete emptying during winter storage or system maintenance.
