What is Leaking Steel Union?

Submitted by: Administrator
In WA State gas unions are not allowed inside buildings. There are left and right hand couplings and nipples that take the place of unions. No sealant is required on unions faces - the seal is made by the beveled male/female surfaces. Also do not use regular teflon tape. There is a separate type of tape for gas. Really, I think TU555 is the best sealant.
