Propane One Pound Tank Refill Adapter

This adapter will allow you to refill the green 16.4 oz propane BOTTLES (Coleman, Worthington, etc) or the blue 14.1 oz BernzOmatic from a standard 20 lb (5 gal, well 4 gal if fitted with the 80% fill valve limiter) TANK. (I refer to the cylinders as bottles and tank for clarity below.) Some tips for a satisfactory refill: You DO NOT need to freeze or warm anything. The bottles DO NOT have to be empty. You DO need to wrap a couple turns of teflon tape around threads of the adapter and then tighten it onto the tank BY HAND until it seats - if it becomes hard to turn after a twist or two you are cross threading so back it out and start again. If you force it on with a wrench when cross-threaded it will leak and cause you needless frustration, so tighten by hand. Now take a wrench and give it another 1/2 turn or so. You want adapter tight on tank so that it doesn't come loose when screwing on and off your bottles. You DO want to transfer only the liquid propane from tank to bottles. This means you will have to lay tank on its side if more than 1/2 full and completely upside down if less than 1/2 full, otherwise you will just fill bottle with gas. You DO want to LOOSELY HAND TIGHTEN your bottle onto adapter. It DOES NOT need to be cranked on. It won't leak. Just snug it up using your thumb and a couple of fingers. Now open valve on tank. You will hear the liquid swishing into the bottle. Wait until you can't hear it anymore. If your bottle was completely empty this will take about 10 seconds and your bottle will be about 1/4 full (maybe 1/3 full if you heat tank and freeze bottle) but it doesn't matter. Now see that 1/4 inch hole with the pin in the middle on top of your bottle? That is a pressure relief valve. You can take a pair of needle nose pliers (the kind with the tangs bent at 90 degrees make this easy) grasp the pin and pull it up a tiny bit. Gas will vent out from bottle and the swishing sound of more liquid going into the bottle will resume. You can continue to let out gas until liquid spews out (careful, it's very cold). If you have the bottle turned so that the valve is at the top half of your horizontal bottle when the liquid spews out, your bottle will be about 90% full. Release pliers, close valve on tank, and unscrew the bottle. You will hear a little whoosh as it comes off adapter. Take a fingertip full of petroleum jelly or vegetable grease and wipe it into the relief valve hole. It should stay there. If not, you can wiggle pin to get valve to seal. If it takes a lot of manipulation to get it to seal, don't refill this bottle again, because you probably bent the pin. If it will not stop leaking, not to worry. You can either place bottle on a stump and from about 100 yds shoot it with your rifle or, if the kids or wife are around, you may want to mix up some JB Weld or Fix All, wait until it's almost set and stuff it into hole keeping your finger over it until hard (about 30 seconds). You should rarely, if ever, need to do this. I've refilled 1000's of bottles and only had to shoot two. :) I usually get about 14 full bottles per tank. The adapter paid for itself the first tank. Follow usual precautions about nearness to open flames, sparks, etc, or you will lose your eyebrows or blow yourself up.

Works great, helpful tip freeze the small bottle first that allows you to get more volume.

Turn the 5-gallon propane tank upside down to refill a 1-pound canister. Compare the recharged canister with a new one by weighing it, if you have an electronic balance. You won't fill the old canister as full as a new one, but you can get close, depending on how old the old canister is.

This little device is great if you want to save some money on propane. I use a lot of the one pound propane bottles and I usually spend about 6-8 dollars for a 2-pack at Wal-Mart, who consistently has the lowest price on propane. Compared to refilling a BBQ tank, the cost of the one pound dispoable bottles is double to triple the price. While this adapter is quite pricey (it's worth at least half the cost), it pays off in the long run, especially if you run through disposable bottles like I do. To ensure a good fill, the instructions say to chill the bottle first. Put the adapter on the 20 pound tank, then screw the chilled 1 pound bottle onto the adapter. Turn the larger tank upside down, and turn on the valve. The chilling creates a pressure differential inside the bottle compared to the tank. After about one minute, it should be full, but you can hear the flow, so just shut off the valve when you don't hear anything. Finally, remove the bottle FIRST. This is very important because if you remove the adapter with the bottle attached, you'll get a spray of liquid propane, which is extremely dangerous. A few tips: - Make sure the tank that you are refilling the bottles with is full. I tried refilling the bottles with a 1/4 full tank, and I could get no more than a half-filled bottle. - I find that purging a slightly empty bottle does a better job at cooling the bottle than freezing does. Of course, you're releasing propane into the atmosphere, so I'll let you decide if this is a better method for you. There has been a lot of debate regarding the legality of refilled and transporting the bottles. I thought I'd offer my thoughts on the matter: - Many argue that refilling disposable bottles is unsafe and the bottles may leak or explode. As long as you play it safe and avoid refilling damaged or leaky bottles, I can't see why it would be an issue. These disposable bottles are designed for pressures that are much higher than the propane can produce at normal temperatures. No one is going to sell bottles that are about to explode, unless their business model is bankruptcy. As long as you don't keep the bottles next to fire or other heat sources, you shouldn't have a problem. - Others argue that you can go to jail and face a fine for transporting the refilled bottles, citing various laws. If a police officer sees a propane bottle and asks you if it is refilled, are you really going to say yes? The laws are put forth to prevent people from selling refilled bottles. I doubt anyone is going to be knocking on your door asking if you've been refilling your bottles. Overall, this is a great product. As with all products, you should understand all the risks involved and act accordingly. As for me, I'm going to be keeping this handy adapter.

How can you dislike a brass fitting especially when it does what it's supposed to,refilling Coleman 1lb cannisters,the label inside folds out like a book and inside are the instructions for use ! If you shop around it can be found cheaper but with gas do you really want a knock off

I’m very satisfied thank you.

Exactly what I required. thanks

Makes the price of portable gas for small blowlamps affordable.

Could save me pounds!
