regulator leak

[Duane]

I just bought a used regulator that leaks at the nut attaching it to the cylinder, even when screwed on pretty tight. It's one that does NOT use a regular washer, but has a quad ring washer built in.

I thought I'd try to replace the quad ring, but I can't seem to get the old one out. Can I just put a regular washer in on top of it? Would that do the trick?

Thanks

For the price of a plastic or fiber coupler washer, it's certainly worth a try.

[Not a fan of the integrated o-ring style regulator stems...]
