Brass nut 1/8 for 6mm welding cap
A welding end cap nut is used to put pressure on the welding cap so it seals against the conical surface of it. Once there is not enough pressure from the back from the welding cap nut, the seal won’t work.
Welding cap nuts can be interchangeable for various sizes of welding end caps.
