Leaking 1/2" union -- face on a lathe?
Awl --
It's an old-style union (flat mating faces), immediately on my compressor, with the controls and fittings on that. Should be a quick job, if it will work... will save me a trip to the store. Plus it would be but another DIY thrill.... :) Alternatively, can I just putty/dope the faces up? I know this is a no-no in water plumbing, but mebbe it's an OK stopgap here? Even tho the psi are higher -- 120 air vs. 60 or less for water. -- EA |

Why not get out the razor knife and some oaktag or gasket material and cut yourself a gasket? Someone did a dope-but-no-gasket replacement on my car's water pump. When it needed replacement, I found that the housing parts were glued tight and couldn't be budged. No gaskets meant that the attaching bolts were a couple of turns tighter, and went into the engine block past the fully-cut-thread length (so the bolts broke, of course, at disassembly time). |

Does not work and you have to get another union. But it might be easier to use some valve grinding compound and lap the joint smooth. Dan |

Heh, no washer, which is proly the real problem, given this style of union. I'll go and see what fits, mebbe a garden hose washer will do.. I can always cut a washer from 1/8" rubber. It doesn't take much of a leak to empty a tank overnight. -- EA |

It's 120 psi. Fiber would proly be good, or nylon. I put in a nylon-ish washer, leaked a little, tightened'er up, rock solid now for hours at 105 psi. .... Good to know - thanks for closing the loop. Bob |
