Replacing a propane pigtail

The pigtail to one of my propane tanks has cracks in the hose, so I want to replace it.

When I put in the new one, it flunks the soap bubble test. There are bubbles between the brass fitting on the end of the hose and the brass fitting on the regulator.

The new one’s package reads “RV Thermo Pigtail 1/4” Inverted Flare”.

If I switch back to the old one, it works fine.

Is there some trick to changing these?
  • There are at least two different type fittings. Years ago I replaced my high pressure regulator valve and the old pigtail would not fit it. Had to take the fitting from the old regulator and install it on the new one. You might be able to buy an adapter. Check your local well equipped hardware store.
  • Instead of a 'flared fitting' I would imagine your LP Reg needs an 'Inverter' fitting
  • Not sure. Why not take it to your local Blue Flame or other propane shop and ask them? I've used the BF shop guys before to make up custom hoses and parts for me. They're great.
