Propane tanks, appliances and connectors?

I am in a propane nightmare! I am trying to connect a propane tank (5 gallon type that you get filled at the gas station) to an old propane stove that we're going to be using for canning. It's out on the porch.

I am totally confused by all the connectors, types, etc!

From what I can understand, I have a tank with a quick-connect 5LP-A valve.

My stove has a connector that is a female, threaded end (ie the threads are on the inside of the connection).

I have 3 hose / regulator setups from walmart, and I don't know which one to use. None seem to fit either stove or tank.

I have a TYPE 1 connector and regulator;
a POL connector and regulator;
and a 4 foot hose and regulator that connects to "most refillable propane tanks" - except I don't see a regulator on it at all!

I'm thinking I will need some type of adapter for this quick-connect valve on the propane tank (or just should go get a different tank from the 10 or so sitting in the shop), but even so, I can't figure out what should go in that connector on the back of the stove.

Both of the hose / regulator assemblies have a male end (threads on the outside) that LOOKS like it should fit, but it doesn't seem to screw in.

Is it me, or is this nuts???

Thanks for any clarification! I've been searching the web, but just finding parts houses and I'm not getting anywhere.

On the propane tank, the POL connector screws in counter clockwise.

On mine the threads are reversed. Try screwing it in reverse or counterclockwise. Daryll in NW FLA

Okay, just went and looked at the tanks in the shop, and every single other one has a valve with a female end (threads on the inside).

Is that POL or Type 1 or something else? What is the new kind that gas stations require? (I'm amazed ours filled up this one with the quick connect. I don't think they were supposed to!)

Do the terms POL and Type 1 also apply to the appliance end of things, or are there other terms for those connections?

Thanks!

Get a new tank or get a quick conect adapter to hook it up. Regulator 1 will hook up to any tank except the quick conect. Regular 2 wil hook up to any new stile tank . CAn't tell about the stove but if it is a 3/8 fiting it will hook up to either regulator 1 or 2. If it iis a 1/2 inch you need to get a adapter to reduce the diamater or bet a new hose on the stove. Regulator 3 doesn't hae a regulator so you should not use that one on a stove.

What kind of stove is it that you are trying to hook up to? If it is a regular kitchin stove It will probily have a 1/2 inch conecter. If that is what you are useing it will only burn one or two burners at full spead.

After thinking about it The quick tach one is probily not LP. It looks like a air tank. That is probily why you can get it filled at the service station.Quick tach is not used for flamible gas because they sometimes leak. If it is for LP then it is not legal in Arkansas.

To hook the hoses to the stove you need to remove the pipe that comes out of the stove and replace it with the one on the regulator. You may still need to buy an adapter to hook it up with.

Mousebandit,
For safety's sake, get rid of that bayonet fitting on the gas tank - it appears to be a Rylco fitting, used for air hoses. Theye are inclined to leak somewhat - not what you'd want with gas.
Can you post a photo of the stove and its connection? If your stove normally runs directly off a small gas bottle, you won't need that regulator.
Most male threads on gas fittings are anti-clockwise, to prevent them accidently being attached to air systems.

Fittings

I'll take a stab at identifying the fittings you have.

The photo you have labeled propane tank shows a quick connector. They were sold and used for propane back in the 1970s but were never recommended due to strong chances of leakage. They were typically used on portable BBQ grills. The 20# bottle you have should not be refilled (legally) until the valve is replaced with one that has an overfill protective device. I believe all OPD valves come with a three cornered hand wheel to open the valve as a means of identification. Home Depot and others sell 20# bottles typically for $24.95 so it might be time for a replacement. Valves can be a hassle to replace without the proper tool. OPD valves can be purchased online for about $7-$8 less shipping. You local company installing a new valve will probably charge more than what you can buy a new bottle for.

The photo you have labeled stove appears to be a flare fitting, but the Teflon tape residue in it indicates it to be a pipe fitting instead. Sorry, but I can't see the fitting to know for sure. I wouldn't use the flexible gas line the fitting is on unless it is inspected thoroughly for cracks. They are known to crack from the flexing from connecting and disconnecting. Not sure what the actual fitting on the stove is but the flexible gas line is basically an extender to make the connection before the stove is slid into position.

The photo you have labeled regulator #1 shows the perfect example of a POL fitting. That particular one has a rubber O-ring to help it seal. The fitting on the hose end appears to be a 3/8ths inch flare fitting, but that is only a guess without seeing it in person. I noticed the Made in Italy regulator, so who knows what it might be. lol.

The photo you have labeled regulator #2 is what is used on the the newer propane bottles instead of a POL fitting. The hose end appears to be a 3/8ths inch flare fitting, but as in the last ID that is a guess.

The photo you have labeled regulator #3 is an adapter. The propane tank end is the standard POL fitting. The other end has the threads and fittings of a small disposable propane bottle, often known as a Coleman bottle of about a quart size. These thread are used to connect replace the disposable bottle so that a larger tank can be used. They connect directly to propane lanterns, camp stoves, small BBQ grills that use the disposable bottles, small propane torches, etc. I use one so that I don't have to buy disposable bottles at greater cost per gallon of propane. Many stores also sell a distribution tree which is a pipe like device that connects to a 20# bottle and extends into the air. At the top is the aforementioned thread style so that a lantern can be placed. Along the side of the pipe is one or two fittings so that a camp stove can be run off of the same 20# bottle and another normally disposable bottle appliance.

Those are my best guesses on the fittings without seeing them in person.

Windy is right on, I'll add that the flex hose most likely has flare fittings on the end, but someone incorrectly applied teflon tape to the threads like they would on an NPT fitting. There shouldn't be any tape on flare fitting threads.

Okay, so bon voyage to the tank with the quick-connect fit on it. Will pick out one of the ones in the shop with a triangular handle and fill it up.

Now, to remove that flex-pipe thingy from the stove, do I have to remove the back or anything? It looks like it just disappears up inside the back of the stove somewhere. What should I get to replace it with?

Duh on the adapter - I should have recognized that, as we have one of those tree adapter things! You can see how often I set up the propane stuff at camp, LOL!

Hubby's back in town now, but I would LOVE to get this set up by myself today while he's at work and surprise him with some home-canned stew tonight!

Thanks! I'll get dressed and go look at the back of that stove again!
