L/P quick disconnect

The 25,000btu LP quick disconnect is not putting a lot of gas out to run my Blackstone grill anybody have any issues with the LP Quick disconnect?

Works just fine if I disconnect the valve at the tank and run it that way.

Your grill may have its own regulator. This is the problem from what I'm reading from your description....


What happens is that the Airstream regulator is reducing tank pressure from 150 pounds per square inch (PSI) to something like 9-11 inches Water Column (WC) for the Airstream appliances. This is what the Airstream regulator and propane system is designed to do. The quick connect port is on the low pressure side of the Airstream regulator...so you get only that very low pressure to the grill.

Your grill has a regulator designed to input 150 PSI or so, and regulate down to whatever the pressure the grill needs. That's why its not working properly off the propane port--not enough pressure to get your grill regulator flowing enough gas.

Your best bet is continuing to hook up to the tank directly. Otherwise, you need to know the output pressure of the regulator on the grill, and bypass it if it is in the right range to use the Airstream regulator directly. See if your grill offers a "low pressure port" accessory. If it does, get one...

If not, if the current grill regulator delivers 9-12 inches WC to the grill burners, you could take the grill to a propane supplier with a full-service shop, and get the correct parts to bypass the grill regulator and hook direct to the Airstream regulator.

You could do it yourself, but you best know exactly what you are doing--being in the center of a rapidly expanding propane fireball can ruin your whole day if you get it wrong...

Rmkrum, thank you for the very informative post, I learned a lot. I think I will stick to using the small portable tank for the moment.

You are quite welcome...glad you found it useful!

The similar discussion on how to hook up a Champion Dual fuel Inverter generator went on for pages and pages...

Using the quick connect on an Airstream is not a simple subject, apparently.
