The teflon tape is not working?

You should not need teflon tape on air couplings.


Looks as if I wasn't the only one that miss-read the OP. Sorry 'bout
that. I use the cheap couplings from HFT but found the BRASS versions
better than the STEEL (Pot metal?) set I returned as I found the
thread tolerances way off. Most of my leaking issues are with threads
(and, lately me bladder).

I missed the original post but I'll chime in here. If you can find
Cejn couplings you won't go wrong. I used to own an air tool repair
company and we sold Cejn as well as using them. I had one on our
repair bench that was connected and disconnected constantly 8 hours a
day, 5 days a week for over 10 years. Every so often it would start to
leak but there is a screwdriver slot on the end and a slight twist
would seal it right back up. Others around the shop that saw less
frequent use never leaked or needed tightening. I sold thousands to
customers and never had a complaint.
