OLD TT. propane hook up question
« on: July 19, 2017, 02:55:19 PM »
I have a 1973 TT that has a very old type propane connection. Question is do they make some kind of retro fit adapter or something to get the propane hooked up? Thanks Chris

Do you have real old portable tanks? If you do, they will probably need to be certified. It may be cheaper to just replace them. Is this what you were asking about as far as a adapter?

Look inside the valve body of the tank valve. You'll probably going to see some female threads. Will your male fitting screw into that? If my memory serves me correct, they'll be left hand threads I think.

Two answers.
1: Yes
2: or you can replace the hose with a new one

Most Propane WHOLESALE places or RV dealers can fix you up.

I believe the newer tanks do both male and female

The old POL-type screw-in gas fitting were the standard for 50+ years, so almost surely what you have. Trailer (male) side looks like this:

New tanks with the Acme thread fitting most always are dual-purpose and also have internal threads that will accept the old POL male as well.   Since the new standard tank valve accpets the older style, there is no need for an adapter.

You can also change the old POL fitting to the new Acme-thread type. It's just basic plumbing and any hardware store will have the replacement part.

DOT-spec LP bottles were the same in the 70's as they were back in the 50's and stayed that way thru the late 90's.  The standard LP bottle valve used a POL fitting that screwed into internal threads in the tank valve. That didn't change until 1998 when the NFPA 58 gas code changed to require Overfill Protection Device in portable LP bottles. The revised NFPA 58 went into full effect on 4/1/2002.

If yours doesn't fit that, you have either an oddball tank or an oddball fitting on the RV. Need photo or measurements.

Your LP system also requires a pressure regulator, and the connection to the regulator is typically a 3/8" flared brass fitting. Maybe what you are looking at is a flare fitting and you need a regulator in between the gas tube/pipe and the tank. Here are some photos of a basic single stage LP regulator:

I would probably just replace the pigtails and maybe the regulator too. If it's original it may not work.
