Mr. Heater F276140 1"-20 Male Throwaway Cylinder thread x 1/4" Female Pipe Thread Fitting,Multi

This does everything you'd expect, with no hassles or "oops, forgot the <whatever>". Of course, it's part of an overall connectivity solution, so you still need whatever quarter-inch connector you need to connect up to your propane source, but this acts like a throw-away bottle, without the cost of those wretched (but nicely portable) bottles. So, if you have an RV or travel trailer or a big propane tank with some sort of way to attach a hose, and you want to run your small propane appliance, grill, heater, fire pit, or whatever that has a "portable throw-away propane bottle" connector, this is what you need to do propane in bulk and avoid using the bottles unless you are far from any bulk propane sources.

I bought this along with a Mr. Heater Male Pipe Thread fitting to fix a problem with the propane regulator on an old camp stove I have. The threads on the old regulator were stripped so I couldn't properly screw on a propane cylinder. This adapter solved the problem perfectly. It screwed in tightly (I also applied some thread locker to make sure it stays in place). Then I screwed the male pipe thread adapter into it which accepts a disposable propane cylinder and the setup works perfectly.

I don't understand why a plastic plug has not been made to protect the fitting where the throwaway Cylinder screws in. Take one of these, install a 1/4inch pipe plug into it and you have a heavy duty protection plug.

Does what God intended it to do. Doesn't stray from its purpose, and doesn't alter its form. I'm highly confident it will still be the same shape in ten years, and still doing the same thing.

I purchased this to plumb in a portable grill into a 1/4" NPT line from a 20lb tank. This little piece made everything so easy as it easily connected to my two connections. I would highly recommend this for this type of use. Just note, there is no pin in this so when you disconnect your appliance you WILL have gas come out unless you first turn off at tank (or another valve) and burn off the extra fuel in the line prior to disconnecting.

If you want to hook a gas heater, grill, or lantern to 20# tanks on your camper, this is the necessary connector. Good quality brass. Nicely machined. Fit my Mr. Heater perfectly. We're warm and happy not having to worry about the tiny tanks running out in the middle of the night.

In my case, I wanted something without the check valve. I made a bulk can adapter for a golf cart heater that is designed only for use with disposable cans. When everything is connected properly, trying to start the heater using a 10 foot hose takes a long time and quite a few depressions of the start button to get gas to the heater. So, what I do is unscrew the heater (while outside and away from any ignition sources) just enough to allow unrestricted gas to flow through the hose, then tighten down the heater. Disconnecting is no problem because the hose does have the check valve, although I typically close the valve on the bulk tank so the hose doesn't have any residual gas in it.

Did not fit. Best to get the hose converter.
