Polished stainless steel threaded fitting for use as an air vent, anchor locker drain etc.
Clamshell cover over exterior prevents water entry from waves or rain.
The vent is not fitted with a gauze, so is not suitable for fitting to fuel tank vents.
The vent is held in place by a nut which is tightened at the back of the vent. The threaded part is available in different BSP sizes and can be connected to another fitting (eg hose tail), fitted to a hose or cut short to use as a drain from an anchor well or locker.
