LP hose check valve?

I carry a small gas grill with a 13’ hose and I hook it to the RV tank for cooking. I’d like to add a check valve at the point that it hooks to the tank so I do not lose the trapped gas when I unhook the hose but have not located one. I have tried shutting it off at the tank, but it continues to burn longer that it took to cook the food on the trapped gas. Any ideas??

The female ACME nut on the hose end has a check valve built into it to prevent gas trapped in the hose from escaping. If yours leaks when disconnected you need a new hose end. This applies to green, red and black ACME nuts.

Quoting from the Marshall Excelsior RV catalog, page 24 https://www.marshallexcelsior.com/si...%20Catalog.pdf

The Type I (QCC) connectors (ME517, ME518 and ME519 Series) are designed with a built-in excess flow feature and a positive shutoff that will not allow gas to flow until the connector is fully engaged. In case of a fire the built-in thermal protection on the QCC connector melts allowing the nipple to disengage from the tank connection and stop the flow of propane. These QCC connectors also provide a positive back check seal at disconnect to eliminate the propane in the hose from being released into the atmosphere.

To connect a Type I (QCC) connector to a cylinder, close the cylinder valve and the control valves to all connected appliances. Hand tighten the QCC onto the cylinder and slowly open the cylinder valve. If the valve is opened too quickly, the excess flow device will be activated closing the flow of propane to the appliance. If the excess flow device is activated, close appliance control valves and wait 60 seconds to allow pressure in the line to equalize. Additional equalization time may be needed depending on the length of the hose. Turn on appliances by following the manufacturer’s suggested lighting procedures.

I would like to help you but I’m not sure what you have. Are you using the 12-foot Amazon hose with a male acme fitting in your posted link? If so, you cannot use a check valve because a check valve only allows one-way flow. If you want to “trap” the unused propane in the hose you need to replace the acme male end of the hose with a valved female QD (quick disconnect) fitting and the acme female fitting on the grill with a male QD fitting. If the grill has its own regulator, use a high pressure QD fitting. If it doesn’t, use a low pressure QD fitting. Externally, they look the same. But the high pressure QD fittings have a smaller internal diameter.

If the gas in the line runs the stove for X minutes after the food is cooked, shut off the valve X minutes before the food is done cooking. Otherwise the QD works.. thats I use for the Wave III heater.
