Leaking Air Couplings
Almost all of my air couplings leak lots of air. I bought them from
Harbor Freight and Home Depot. Is there any way to tight them, so that sir doesn't leak? If not, can you recommend a brand that fits together properly. This air leakage is driving me crazy. I tried posting earlier... getting error messages. If this posts twice, or similar post, sorry. Sonny |

There was a time in my career when I designed quick connect couplings. Based on that experience, will offer the following: 1) Plugs need to be case hardened to minimize scratches. Case hardening costs money which is easy to skimp on without being easily detected. 2) Very accurate screw machine tolerances are required to maintain the seal between plug and coupling socket. Sloppy machining works for a little while, sometimes. You can try replacing the O-Ring in the coupling, it may buy you some time. Plan "B": Scrap them out and start over. Lew |

Sonny If you mean leaking quick-disconnect couplings there is a little o-ring in there that is usually the culprit (a dental pick helps when removing and replacing these). Replace it and keep it lubed with something friendly to o-rings and usually the leak goes away. |

Lew The only ones I have ever been happy with, were the few I bought from the SnapOn truck. They didn't have that 'pot-metal' look and the male looks machined. The ones that came with my Porter Cable pancake compressor/hose combo work really well too. The few from Chiwanese sources simply didn't last when dragged along a concrete floor. Speaking of air fittings and such, I have about a dozen blow-cocks. None. 'cept one, work very well. Anybody know of a good one? |

I USE TEFLON TAPE. Lowes has a heavier (thicker) tape for "Gas
Fittings" that may help if the tolerances of your fittings are iffy. I also put my compressor on a switch leg so that turning off the shop lights turns off the cohmpresor feed as well as the feed to the little power transformers for the battery chargers and such. |

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). |

Interesting idea..
but the flip side says if your compressor overdraws and the breaker trips.. you'll be in the dark. "Hoosierpopi" wrote in message ... I USE TEFLON TAPE.

Why the caps? Why not include the text you are responding to so that we know what your response is in reference to? If your tolerances are iffy, then you're using junk. The best solution to that problem is to get rid of the junk because teflon tape is not going to make junk into a decent product. What does your power feed have to do with any part of this conversation? -- -Mike- |

Do those couplers get daily, or even weekly use? If so, I really want some. We standardized on the Milton Syle M clear back in the 50's sometime and many of the ones still in use are of that vintage. It's not a tire shop, no, but a working farm and they're used as the need arises and certainly aren't pampered. I used them extensively w/ during the barn refurb project for nailers, sander, etc., ... That was a two year or so period of quite heavy use. Other than that, compressed air for cleaning and the almost inumerable number of tires by the time one counts up all the tractors, trucks (from pickups to 18-wheel and all axles combinations in between), farm implements, etc, etc., ... the usage is frequent if not continuous. Don't know how else to characterize it. Here's the link to Milton--any decent supply house should have them. https://www.miltonindustries.com/ -- |

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. |
