These adaptors are designed for fitting standard BSP threaded plastic or metal taps to wooden barrels.
The adaptor is tapered with a spiral thread on the outside to assist fitting and sealing to the barrel. They are fitted by simply screwing the adaptor directly into a suitably sized hole. Glue or sealant is not required.
Tap Adaptors for Wooden Barrels
I was delighted with my barrel, which was of infinitely superior quality to any other barrels I had managed to source locally. It is water tight as advertised (much to my surprise). It was also an extremely reasonable price.
