LP Quick Disconnect

Have purchased quick disconnect fittings to outfit a weber small gas grill and Coleman stove. Leak tested and yellow taped.

Problem. Im not getting any gas flow.

Tanks are both full. Using stove inside. Both bottles opened.


Thoughts?

Did you buy mating pairs? I bought some allegedly low pressure QDs from camping world that were, in fact high pressure and they didn't mate properly with my stove.

If you bought mating pairs, were they for propane gas use? The ones I bought had shutoff valves on them. If you got high pressure QDs they may not work on the very low pressure trailer gas line.

Is the valve on the low pressure outlet open (lever parallel to the direction of gas flow)?

I am having the same problem with my 2018AS27-FB. I have connected the supplied LPG hose to the outlet which is supposed to supply up to a 25,000 BTU service. When connected to my 7500 BTU grill the flame is very low and not adjustable to high. The outside valve is open parallel to the line. When you get some guidance please advise. Thank you, Trinity

Also note that the AS regulator and gas system runs at 11 inches of water column (11" WC) pressure, which is about 1/2 pound per square inch (PSI) or less.

Some grills and other devices have pressure regulators inside that expect about 100 PSI of propane tank pressure directly from the tank, and regulate it down for their internal burners.

Check to see if the appliance has it's own regulator, and if so, you will need a bypass kit or replacement parts to properly work with only 11" WC pressure input.

The super-low flame is a tip-off that you have an extra regulator in the system somewhere. Regulators that are designed to drop tank pressure down to the pressure needed for the burner typically do not flow much gas, if at all, if the pressure is below their normal input rated pressure...

We went through this on the forums when a few of us adapted Champion 3400 watt Inverter dual-fuel generators to hook up to the AS gas system after the built-in regulator. It required removing the Champion-supplied high pressure regulator that is normally fed from the propane bottle directly, and feeding the quick connect flow from the AS built-in regulator directly to the Champion low pressure engine regulator to make them work correctly.

I think this is the same type issue...

Thank you! Each appliance has its own regulator. I have purchased a hose capable of going from my AS tank to the 1-pound tank connection on the appliance. For now this will solve my problem. I will work on removing the appliance regulator followed by a test run. Thanks again.

Some appliances do offer conversion kits.

I purchased the WeberQ conversion kit from MBSturgis (same supplier as the external quick disconnect at the front of the Airstream). After the kit install—which requires removing the WeberQ regulator—mine tested fine. The kit install is easy, just follow the video—most difficult step is unscrewing the Weber Q regulator which has some loctite holding it very stiff. It takes a few minutes to be sure the longer hose fills with LP gas after opening the valve. ��

As others have said, you cannot use the stove or grill if they have their own regulators when connecting to the already regulated quick disconnect fitting on the AS.

Another option would be a propane tee connected to one of the two main tanks, similar to this one from eTrailer: https://www.etrailer.com/question-157464.html

This might be your best option depending on the grill and stove you have. Our grill has the control knob integrated in the regulator. So I can't just remove the regulator without also removing the control for the grill.
