90 degree propane fitting?

I have a Dickinson 2 burner non-gimballed stove I'm installing. The propane fitting comes from the bottom, vertically. I'd like to have it come off horizontally instead. But I can't find a 90 degree propane fitting, at least a marine quality one.

Is this against AYBS standards? I can't figure out how it would hurt anything if it's a solid connection. It would save space. Can't find one from Trident or in the WM catalog or online. I do see some generic ones online but pretty sure they would not be appropriate?

The fitting shown is a brass 1/4" street el which you can get for about $4.00 in a big box hardware store. They're approved for land based industrial gas fitting so the ABYC may approve them as well.

When you assemble the fittings, be sure to use "teflon gas tape" or a pipe dope like Permatex 2. Best not to use the standard white teflon tape.

you can always go to any propane gas store/jobber (yellow pages or internet search) and get whatever you need there.
they will have the 90 degree fitting that will screw into the bottom of the appliance that the 3/8" flare fitting on the hose will screw directly onto, which will be one less connection that you will have using the street el...

and what you get at the propane store will be all quality stuff, but I have found no propane fittings or propane hoses that has an ABYC stamp on them....
In my research, I havent found any propane hose manufacture that will say or claim their hose is rated for, or ok to use in a boat, yet boat manufactures still install the hose....

as for onboard propane systems, there seems to be more regulation on HOW its installed, rather than what is installed.

I thought that non marine brass was a no no and that it was very corrosion prone.

For items like propane and fuel fittings brass is ok. It is underwater that it is a problem.

The fitting you showed is wrong I think. You need a 3/8 female flare to a 3/8 male flare in a 90.

Yes, be much tidier if you can find such a fitting easily. Otherwise, it just means one more fitting to adapt to the flare fitting.

No reason to adapt. They are commonly available and easy to find. First hit on google. http://www.plumbingsupply.com/flarefittings.html
5th item down the page. We sell them in Victoria as well as most any plumbing supply.

The fewer connections the better.

Just ordered one...I was trying to understand all these different threads and finally just gave in and bought the one you mentioned. Hopefully it fits.

Confused what "NPS" thread is, can't find mention of it online.

And you won't find them. ABYC is a standards organization but not a certification organization. For example, the NFPA (National Fire Prevention Association) will develop rules that are addopted into regulations, they will require UL, APL, and similar certified equipment, because those organizations operate testing services.

I suspect a UL 21 stamp is what you will find.

So I got the fitting but I'm not sure that it fits correctly. It's a lose fit and then seems to bottom out on the body of the fitting versus the thread itself. Additionally it ends up putting the hose against the bottom of the stove.

Is there another fitting that would give me free 360 rotation so i can take the hose away from the stove?

Here's a video of the fitting getting tightened down.

after watching your video i can tell you that is not the correct thread size...it may be a pipe to tube fitting ...you may have to find fitting that goes into your stove and on the outside end is a pipe thread in order for the 90 degree
to work

Definitely the wrong fitting. I would have liked to have seen the inside of the threaded part.

..................... which will NOT go unchallenged. We're going to solve this thing even if it kills you :eek:.

I'm almost, maybe, possibly sure that the 90 deg. adapter you're holding in your hand is a female iron pipe thread (FIP) X male flare adapter. And yes, I can see how it may well not be pointing in the correct direction when finished tightening. New pipe threads and tape will give you lots of choice as to where the fitting will be facing when complete.

The fitting which you have attempted here would ideally be a 90 deg. female flare X male flare adapter. Rare as chicken's teeth but available from somewhere I'm sure ?

From the comfort of my armchair here, I'd suggest removing the existing flarerd fitting from the stove if possible. Be VERY careful that you hold on to the female iron pipe (FIP) fitting on the stove as you're removing the existing, fitting. You will now be left with an FIP fitting which is attached to and part of the stove. The ideal fitting you now want is a 90 deg. MIP X male flare adapter. Don't sweat it if you can't find one and just use nipples, 90's and adapters. They'll go together perfectly for what you want.

Make sure all fittings and nipples are brass. Use gas teflon tape and you should be fine.

Please BE SURE to keep us updated on this. I don't know about others, but I WILL NOT REST until this job is successfully completed, regardless of your cost.

PS. your attention to detail with the video is perfect for detailng the mismatch.
