If you change the valve knob on the old tanks, with the triangle knob from an OPD valve, no-one filling the tank would know any better. I find tanks with OPD valves at the local dump, some still have propane in them.
I sure wouldn't do this but some would.

They thought of this one. The knobs on OPDs can't be removed. If the cylinder appears to have a standard bolt or screw holding down the knob, then it's been tampered with.

Forgive me if I add some info here, but for safety's sake, do the following:

1. Check the collar of your aluminum cylinder for pound numbers following "TW" (tare weight, i.e., the weight of the metal cylinder alone) and "WC" (water capacity). Not all otherwise similar cylinders will have identical figures, especially for TW.

2. Multiply your WC figure by .42. The result will be the weight in pounds of the propane that you can put into the cylinder.

3. Add TW and WC(.42). This will be the maximum, total weight of the filled cylinder.

After you use your method to fill the cylinder, check the weight and make sure that you are no higher than the total, maximum above. If you are, then bleed; otherwise, you face the possibility of excessive expansion, allowing raw propane to escape, a very dangerous result.

I'v had tanks filled by people that wouldn't notice if the knob were put on with duct tape. At one flying J, I had to show the person how to fill the tank. I thought they were supposed to be qualified for the job

Actually, I was surprised to find that not all states require a license to fill propane. Boy, makes New Mexico seem like it joined the 21st century or something! But even here there's a loophole: An unlicensed person may fill cylinders if a licensed person supervises. Duh. So the person with the license sits inside someplace and drinks coffee while the filler does the dirty work outside.

It's not really that hard. Some basic, sixth-grade math and some middle-school science are all that one needs to understand the process. Oh, and the ability to put out a cigarette before in proximity. (You'd be amazed ...)

The opd knobs are easily removed- all you need is a tamper proof torx bit. I won't do this as I am responsible for my actions.
So um a well canadiens aren't smart enough to refill cylinders? I hope this to be a isolated incident- Shack- as I like the "Great White North". You do a lot of "diving" at the dump?
And eubank- that was a great post on tank markings and weight! (#16)
A scale is a must have especially when transferring to a smaller tank.
Still waiting for my putor.

I bought the little adaptor for my small camp propane tanks... So I need to invert the big tank to fill the little one??? won't the propane come out if it is right side up?? I haven't tried filling one yet....

Tried shooting one..Just hissed... disappointment.... Tried shooting a big one that was empty... even a 9mm wouldn't go through it.. not made of aluminum though... old style, it was junk...

I want to fill the small ones so I don't have to keep buying them,, Seems such a waste.....

Use a caliber that starts at least with a 4...

By inverting the tank, you transfer the propane in liquid form. Then as you use the appliances, the liquid converts to the gas you are burning. You wouldn't be able to transfer enough propane in the gas state to be effective.

More on propane filling

As a licensed person, I can't and won't recommend refilling a cylinder that is marked "no refill." That said, if you decide to do this, a little physics is needed:

1. Propane is heavier than air, so you have to invert the donor cylinder.

2. The propane that comes out of the valve under normal use is gaseous, not liquid. It is the result of the liquid propane inside the bottle boiling (that is, conversion from liquid to gaseous state).

3. Boiling points for propane (and for just about anything else you can imagine) are subject to atmospheric pressure (usually just elevation) and to ambient temperature.

4. The air above the propane inside the cylinder is also subject expansion with elevation/temperature and can, under certain cirmstanances, exert so much pressure down on the propane in the cylinder that the boiling point of the propane is adversely affected. In such a case, it is necessary to vent the excess air pressure. Please allow a propane filler that you trust to do this.

5. Always carry your propane cylinder, especially a newly filled one, in an upright position, and have it open to air (not in an enclosed vehicle, for example). This is so because propane can expand greatly with just a little heating, and propane can be released into the atmosphere via the relief valve as a result. A full propane cylinder on its side in an enclosed vehicle is a recipe for a very unwelcome event.

The propane guy down the road hooks it up, turns a screw, has it on the scale, when it's full turns the screw and shuts the valve... My 2.5 year old could do that..... Not that I would stand near him.....HA.

I will give one a try to see what happens....Later.... If you don't see me on here for a while you know it went bad.....

purman- put the small EMPTY cylinder in the fridge for 15 minutes, then remove it a screw it onto the adaptor most rickey tickey. Invert the donor cylinder and let 60 seconds pass. Upright the cylinder and shut the valve immediately, Unscrew the camp cylinder. It helps to weigh the cylinder when empty. FYI the small cylinders I have weigh 14.5 oz. empty.
So here's the pics.

I have an 85 Excella with the readout panel inside, but the valves on the tanks have been changed. Now the gauge for the propane tanks doesn't work because there is nothing to hook it up to on the tanks. Does anyone know if these sending units are available on the new style valve?
