Propane disconnect

[denk]

In my new to me Motorhome, there is a quick-disconnect propane fitting in one of my bays, what type and where do I find a hose to connect this fitting to my Coleman grille in place of the small gas bottle?

With that attachment, it is highly unlikely that was an OEM install. I DEFINITELY would follow the line to see if it is high pressure or low pressure.

Here's the set-up that came in my coach

If time permits, I'll go to the storage lot today and take a photo and try to trace the line. Thanks for ll the interest.

Only if you're certain that the T between the main tank shutoff valve and the regulator (if there is one) feeds the quick connect you found in the other storage compartment.
Trace the hose/line. Be certain.

Chuckle. If there IS a "T" in the high pressure line, you should follow the line to be sure it is what feeds your disconnect. If there is no "T" in the high pressure line, you have a definitive answer.

Ah yes, the infamous "they". 😉 I'm well aware "they" do make high pressure disconnects but not on RVs. I'll repeat - the OP's quick disconnect is low pressure - guaranteed. 😉 It will be just another tap off the post regulator feed that runs to the rest of the interior devices in his rig which by code must be low pressure. High pressure exterior feeds as used by some manufacturers in the past, Fleetwood Folding Trailers' Grand Tour series being one, were always terminated with a 1"-20 threaded male connector, the same fitting used atop 16 oz propane canisters. Code allowed the manufacturer to run a regulated high pressure feed (~ 16 p.s.i.) to these exterior mounted connectors which could then be used to run a separate high pressure stove supplied with those trailers or even a grill such as a Weber Q, without any need to remove the regulator. As a former FFT owner I'm well aware of the differences between low pressure, regulated high pressure, tank high pressure, and how each might be presented on an RV.

I'm glad you are certain that codes and standards are ALWAYS followed. Yours must be a very orderly world. In my world, it is sometimes necessary to actually check to see if something was done properly. Enjoy your world while I continue to check things in my world to be sure I don't have problems.

Have a nice day.

(BTW, I am 99.99% sure that you are correct and it IS low pressure. However, without checking, I am not going to "guarantee" that since I am not accepting responsibility in the unlikely case that it is not.)

If the quick connect looks like this photo, it's def. low pressure and what you'll normally find on RVs. They have a shutoff valve on them so you can't insert the male fitting without the gas being shut off. Note that quick connect fittings for propane on RVs are different than for natural gas as well as compressed air so don't buy the wrong parts. RV quick connects are usually plumbed directly off the line running fore/aft that supplies the fridge, furnace and water heater. You want to remove the regulator on the grill so you don't have two regulators in series.

I removed the regulator on our old Coleman Roadtrip grill and on our current Weber Q. The Coleman was harder to do because of the parts involved. I'd suggest getting a 3/8" diameter hose instead of 1/4" for better flow and also getting one with the rubber type jacket because the hose is much more flexible and easier to coil up than the vinyl/plastic jacketted ones.

My 2002 Roadtrek had a quick connect, factory installed, and it was plumbed into the mix right after the main tank valve, such that it was high pressure. It worked fine using a Napoleon TQ285 and a Weber Q2200 without removing their regulators.

If it is a screw connector like the top of a one pound LP bottle, it is high pressure. If it is a plug in connector, it is low pressure.

If so, all you need to do is remove the regulator and get a hose with a quick disconnect nipple at one end and a fitting at the other that will screw into your Road Trip where the regulator normally would be.

They DO make high pressure propane quick disconnects. There is a need to trace the line. Scroll down about halfway on this web page to find the high pressure stuff.

I'm using a Coleman LXE Road Trip which has a regulator that screws to the 'backside' to accept a 1 lb green bottle.

I'll have to trace my coach's propane line to determine if it's high or low pressure.

Trace the hose/line. Be certain.

Most likely is low pressure.
