Whoever told you that did not know or understand about Teflon tape.... It is approved for LPG and generally the Yellow color tape is used, but you can use white as its the same chemical make up... Personally I hate the stuff, and use old style "Pipe Dope"....

I am wondering why not use a tank mount regulator and then rubber "flex connector" between tank/regulator and rigid piping.... Solves issue on whether to use vertical/horizontal regulators and mounting issues....

I looked it up last night to. But I'm old and I don't even remember if Teflon tape was around when I first helped with piping/plumbing. I saw it said Yellow I've never seen that at a Home Depot or that type of store. I do know that my local LP gas company friend isn't allowed to use tape. I'll stick with dope.

Rectorseal #5 is great stuff for a lengthy list of applications including LPG. product data sheet


There is a difference between the white and yellow tapes. Yellow tape is listed (approved) for natural gas and propane use. White tape is not. Yellow tape is thicker than white. I'm uncertain if that is the only physical difference, but an inspector will red tag a house with white tape.

Note, that ape and rectorseal are only for threaded pipe fittings

That occurred to me as well! I think this is the way I'm going to go. I was up late last night trying to find all the right parts online.

Here's my list:

• Camco 59323 Horizontal Two Stage Propane Regulator
• Camco 59344 Two Stage Regulator Cover - Pack of 2
• Camco 59923 Green Propane Acme Nut - 200,000 BTUs
• Mr. Heater 5-Feet Propane Hose Assembly, 3/8-Inch Male Pipe Thread x 3/8-Inch Female Flare Thread
• 1/2" MPT to 3/8" Male Flare Adapter (to insert into my 1/2" black pipe tee)
• 3/8" Flare Nut

Just ordered the parts. I'll post up pictures of the completed project later this week.

Got my regulator, hose, etc. and finished mounting the pipe under the trailer this morning. A thread is nothing without a few pictures - so here are some to wrap it up.







PS. I haven't pressure tested the system yet, so you may still hear from me yet.

NOt quite sure what you are showing here...



But if clamping bar of u-bolt is just resting on cross member to support pipe, it probably will not stay there... Concept of clamping is good, but u-bolt should also straddle frame crossmember not just resting on edge...

It is a little hard to see, but it looks like the frame is drilled and the u-bolt goes through the lip not just resting on it.

The u-bolt is drilled through the frame. It's at a slight angle so the ubolt plate extends a little beyond. I used two nuts to tighten and two lock nuts to keep it from coming loose. It's super solid.

Cool....

Well "Z" man I think it's about time we got a picture of that stove burning bright.

I know you are on teardrop time but we all want to see if we did well in assisting you.

You are right! I am on teardrop time. After getting the gas line plumbed, I shifted over to the ice box, sink and DC system. I really should go back and test the propane!

I'll be taking my trailer in soon to have the rooftop AC installed and can pick up a propane tank then.

I'm almost ready to hook up the stove to the tank and test everything out.

In the mean time, I've finished most of the kitchen area and have run into a problem. I had to resize the black pipe coming up into the trailer to place the shutoff valve on it where I could reach it easily. That made the length from the end of the valve to the stove input just a little longer than 24" and a little less than 36". Thus I'm reconsidering using the yellow flex tube.

I think perhaps I should use flexible copper for the last little bit as it will let me get exactly the length I want. Thoughts? Sources for tubing?

Realistically the only shut off valve you need it the one on the propane tank. I picked up flex copper tubing and flare fittings at a local HVAC supplier.
