How to Remove Quick Disconnect Adapter From POL Fitting on DOT Propane Tank
Updated 07/06/2026 | Published 06/09/2018
Question:
I picked up a new old propane tank that has a quick release adaptor on it. I cant figure out how to get it off so I can use the tank properly. Please see the picture I attached so this makes sense.

There isn't really any advice I have on removing the quick disconnect fitting other than getting a wrench and plenty of elbow grease. It's in a POL thread which means it's a left-hand thread so keep that in mind.
Once you get the quick disconnect out you can use a standard pigtail hose with a Type 1 ACME nut like part # 100473-12 on it.

Its easy. Pull back the release. Remove the little retaining clip. I removed mine with my fingers. If you're planning on using it again, push out the three retaining bearings. Im not reusing mine, but once you start to turn it, they fall out. I used vice grips, not very tight, its reverse thread, and it turned out with ease. If you plan on using it again, I'd wrap a rag around it to protect it. Its that easy.

Thanks Charles - did not know these POL Fittings have a reverse "INNER" thread (counter-clockwise to tighten), while the "OUTER" thread is standard (clockwise to tighten). I used a thin set of vice-grips to lock down and loosen the quick-connect fitting - its shouldn't be that tight, if it is...may wanna check the bonnet packing within to see if it has been smashed/damaged from over-tightening...test for leaks with a spray bottle of soapy water (google it) - if its leaking replace the packing or replace the valve/tank.
