Question:

I have a 2019 Grand Design 5th Wheel 295RL. I need to replace the propane pigtails and cant find the correct connection. The NPT 1/4 is too big and the 1/4 inch flare is too small... the original doesnt look like a flair. Any ideas on which part I need? Thanks!

Hey Jeff!

The pigtails that go from a propane tank to the regulator will either have the 1/4" Male NPT fitting like what we see with part # 100473-24-MBS or the 1/4" Male Inverted Flare fitting like part # 100575-24-MBS.

If your regulator has the adapter fittings on it already (see attached photo) then you need the inverted flare fitting. If those adapters aren't on your regulator then you need the standard Male NPT fitting.

Have you tried both options already?

Hey Jeff, Did you have a chance to try both the NPT and inverted flare fittings to see which one works with your setup? I'm eager to hear how it turned out, as it could help others facing a similar challenge with their propane connections.
