A sounding cock closes off the upper end of a sounding pipe, the small pipe that runs from a tank up into the engine room or onto deck so the crew can measure liquid level with a tape. Inside machinery spaces, oil and fuel tank sounding pipes must have self-closing devices, so a sounding cock uses a weighted lever or spring that snaps a plug or ball shut as soon as it is released. This prevents fuel overflowing or vapour escaping if a tank is overfilled.
Hamza Fasteners supplies bronze and brass sounding cocks in JIS sizes 25A to 50A, threaded or weld-on, with weighted levers and screw caps, plus test cocks for checking the line before opening. They are fitted on fuel oil, lube oil, bilge and fresh water tank sounding pipes during new-build and repair. Send size, connection type and class requirements to our Dubai team for a quote.
