Leaking Ewarts Tap

[Lowbarn]

I need to fix my leaking tap.

Does anyone know of a decent secondary tap I can fit in place of my current offering?

The original tap leaks out of the carburettor.
I’ve stripped the tap once and cleaned it out, I think it’s still using the cork seals.
I’ll have another go using viton seals.
If that doesn’t work I need a decent tap.
Thanks.
Richard.

A good plumbing merchant would stock a female to male ball valve that you could be installed under the original if you insist on keeping that and then your copper tail attached, or extended to the carburettor
