I had to use a brass threaded street 90 male and female on chrome plated male nipple on commercial facet. It's trying to seep with Teflon tape any suggestions
Disassemble the fitting and try RTV silicone from an auto parts store. Allow the joint to set up overnight if possible. Brass fittings are hard to seal, and do not tighten too much. Brass is soft and will stretch. If you have tightened to where almost no thread is showing on the connection, you may have to replace the fittings. No teflon or pipe dope, just RTV silicone.
