Propane Pigtail, NPT or flare?

I saw "DeadMentally" as your name for some reason.

That's not very nice.

Not copper! Brass!

I would stay with the copper tube and brass fittings with the flare.

RV history:

Here is parts from a 1972 Winnegabo.
It uses solid copper to connect the tanks to the RV. What a nightmare, though if careful it should work fine.


This is the line that ran from the tank to the reg.


This is the adapter to let a flare fitting fit into an NPT.
The copper pipe goes through the nut and flares out at the end.


This is a fuzzy pic, I was trying to show the inverted male flare that is inside the nut. You can't see it but the smaller hole is the tip of the flare.

You are not missing anything. Get what you need and move forward.

I would never use google, goodness with all the hate stemming from those people... there are many many other internet search options that do not hate our country.

so, problem solved, but why would a two tank system need to add an adapter and have a flare hose fitting vs having the NPT fitting? Both styles have the NPT on the regulator it seems, just that one has an adapter thread into the NPT so you can thread in a flare hose instead of threading an NPT hose directly in. What am I missing?
I have a very old reg that prob has the adapter in it.

This seems to be a left-over from ages past when the dual tanks used solid copper lines to go from tank to regulator instead of rubber hoses. These copper lines/tubes were flared so needed to have a flare adapter to fit into the NPT of the regulator.

It is not the regulator that is different, it is the pigtail.

The official description is that single tank systems use NPT and dual-tank systems use flare, but this is misleading... Both tank systems use NPT regulators but the dual-tank regulators have flare adapters already screwed into them so are called "flare" not NPT. You can unscrew those and use two NPT pigtails just the same. What am I missing (as in RV companies are stupid)?

All this sounds about right for the backwards thinking RV industry.

Yes google "rv propane regulator" and there is clearly an adapter for the pigtails.

I highly recommend moving to two cylinders and an automatic regulator for your RV. Never mind... I now see you have a MH with a single mounted tank.

Either way the fittings need to match. Do not put a NPT into the flare or a flare into the NPT.

Standard non-switch-over regulator are set up to go directly onto tank connection. Mounted straight to tanks.
