How to Identify and Replace the Correct Propane Pigtail Hose

[Kirk]

I agree with the previous replies, but the existence of the Teflon tape does make me wonder who/why it is there? It obviously has been worked on, probably replaced by a previous owner. Since the hose is showing cracking, I would probably replace it and get rid of the unnecessary tape.

I'm not seeing inverse flare adapters on either side. I see a hose screwed directly into the regulator on the left and a short brass pipe nipple joining the T to the regulator on the right.

I would not mess with them unless you are replacing the hoses or they are leaking.

If you zoom in on the pigtail on the left you can see that it is badly cracked. I'd say it needs to be replaced.

To me, the one on the left looks like there is an adapter directly threaded into the regulator, then the pigtail is threaded into it. I will be replacing it. Once I get it off I'll figure out what I have and just replace it with the same.

I've removed the pigtail and adapter. The pigtail is indeed the inverted flare style. I had a spare. It also had the white tape on it. I've cleaned it all off since it isn't required. The adapter also had the white thread tape. I will clean it up and use the correct yellow type. Generally speaking, how many wraps of the yellow tape should be good?

Oatey, a manufacturer of teflon seal tapes, says 3-5 wraps. But the more common advice from pipe-fitter pros seems to be 2-4 wraps. Maybe Oatey just wants to sell more tape?

Also to not wrap any tape on the 1st thread. If you cover that thread, there is a good chance that a piece will fall off and go into the regulator.
There is a right and a wrong way to wrap the tape. Looking at the end of the fitting, wrap it in a clockwise direction. If you wrap it in a counterclockwise direction, the tape will peel right off as you screw it in

OOPs, you are correct, I see two separate hexes on it. One for the adapter, and one for the inverse flare on the hose, my bad.

Thank you everyone for all of the help. The adapter is re-wrapped with the correct yellow tape and the the new pigtail has been installed. Once I re-install the propane bottles I'll check for leaks to ensure all is well. If the hose on the right ever goes, I'll remove that "T" that was installed. I'll never use it. There is already a hose on the other side of the trailer that I haven't had a need for yet.
