propane furance out again

[GlennWest]

Oh, I agree about the bowl. Used that a lot on tractors. Still never seen on propane.

I think it would work , as long as it was sealed proper .

Your insurance agent would disagree. That bowl is in no way gas rated. Dead leg does the same thing, and is gas rated.

It takes a long time for Black Iron pipe to rust enough on the inside to cause issues. If it took 17 years on the Teton, plus whatever it laid around after it came out of the mill, I'd just go back with the black iron pipe.  Clean it good inside, like with a brake cleaner before assembly.

The only thing I can have is aspirin . One 81mg per day . And multiple self adjustments daily .

The sediment bowl has a filtering screen incorporated and is easy clean . Also lets you see what's being filtered  .

 It's a good thing you are joking. LP fittings must be rated for such, a gasoline sediment bowl (cast pot metal) would not be a good choice IMO, they are not designed to be pressurized..

I'm going to ask you to prove that^ . In all my browsing , I have never seen or heard of such .

It seems to me that all the metals used to make such a fitment are impervious to gasoline , let alone propane .

And , at about 10 pounds pressure , it should easily stand up .

The only change I might consider is the gasket for the bowl . I think a silicone gasket might be a bit better .

I don't have to prove anything. Fittings that are rated for gas (not gasoline) will be clearly marked. Often the abbreviation "WOG" is used, for water, oil, and gas. Your pressure estimate is also way high. Sediment bowls only see the pressure of the fuel above them. Our old Case DC 4 tank was 12" deep, so approximately 11" WC. Sound familiar? The propane piping system should be around the same pressure, but a much smaller molecule. You go ahead with your sediment bowl, I'll be standing back a bit.

So right . You don't have to prove anything . The result is called opinion . 

I don't ever recall seeing WOG on any black pipe or so very many other fittings associated with propane . In fact , the only place I've seen 'WOG' was on a ball valve . And , I had to look closely for that .

So , you're saying that these propane systems will have even less pressure than I speculated . Making it even less likely to be detrimental . 

Anyway , no offense meant by any of this . Just thinking of options .

We have had copper tubing on all of our trailers including one that was a 2005 and we sold it in 2018 with over 100k miles on it. Never had an issue with the tubing getting damaged. If it is a concern try running the tubing in a piece of oversize PVC tubing to help protect it in areas that are exposed under the trailer.
