stop tap

A stopcock is a form of valve used to control the flow of a liquid or gas. The term is not precise and is applied to many different types of valve. The only consistent attribute is that the valve is designed to completely stop the flow when closed fully.

    Stop tap ID?

    I have to replace this stop tap as part of a boiler swap. Can anyone tell me the manufacturer? Trying to make it as simple as possible so if I could get a replacement from the same manufacturer I might be able to re-use the nut and olive on the bottom (not sure what the incoming main is made of)

    50mm brass stop tap

    Brand new 50mm stop tap for blue poly and i think others as its the sort with the rubber sealing washers where an olive would usually be. Water board part so best quality. £40 delivered, probably worth near enough this in scrap. Can also get all poly fittings 25mm 32mm etc including pipe.
