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.

Thank you so much the barrel was a birthday gift for me from Ian. And it is lovely exactly what I wanted. The service and delivery was excellent. It smells nice too.
