MORE DETAILS

Cuts off gas flow automatically when pressure is reached.

Pay attention to :
1:You need to turn your bulk tank upside down so liquid flows out of it.
2:You need to chill your empty tanks so that there is a lower vapor pressure in the empty tank than the bulk tank.
3:Your refilled tanks will not be totally full, but this is good because over filling can cause them to vent gas if left in a hot place.

Ordered for my daughter and her fiance who have a gas grill at their apartment that only allows 1 lb cans to be used. Works well. Note that when you remove this adapter from the 20 lb tank, it might back out the inner ring inside the 20 lb tank valve. The o-ring on the male side of the adapter seemed to grip the inner ring on the valve of the 20 lb tank unscrewing the inner ring as the adapter was removed. Then when you attempt to attach the grill regulator to the 20 lb tank, the regulator won't seat correctly and won't allow the plastic outer screw to engage the outer threads of the 20 lb tank valve. If the you have the other type of grill regulator that screws into the opening of the 20 lb valve, it won't go in either. It also depends on how far out the inner ring backs out. You need to use needle nose pliers to grip the inner ring and screw it back into the 20 lb tank valve. Then either type of grill regulator will go back onto the 20 lb tank valve. It worked well enough that we bought a second one.

5.0 out of 5 stars Best $8.59 I ever spent!
Reviewed in the United States on February 18, 2020

So if you are reading this, you are already familiar with the cost and necessity of these little 1lb propane canisters. We live 40 miles out of town up in the Cascades, it takes no less than 4 gallons of gas to drive to town and back to find cans which I can usually get for around $3 a piece, up on the hill here they cost $7.99 each!

When our power bill hit over $250 last month, I decided to break out the propane heater we had to buy last winter cause the one I already had decided it was done working when the power went out for over a week during some major, freak snow storm we had.

I Immediately ran into an issue though. First the power bill drained me, I am on a fixed income, I had two little 1# canisters, one empty 20# tank, one full 40# tank. The 40# tank only has inside threads so the regulated hose only fits the empty 20# tank. Now, I can drive 30 miles for $2.99 propane or 12 miles for $3.99 propane and fill the 20#. The cost of gas kinda makes the choice pretty much equal in cost...about $20 bucks either way.

Living up where we do, I find Amazon Prime is so much more cost effective than having to drive to town any time I find I need something. I remembered hearing something about refilling these little 1# cans so I checked it out.

Now the Coleman cans do say to not refill BUT if you do, the DOT says it is only illegal to transport re-filled bottles. You can legally refill and use these canisters at home or camp. They also sell DOT approved bottles for under $20 you could use to transport legally.

For $8.59 I decided to give this a try and boy am I happy I did. I couldn't even get to town and back on less than $12 right now. I ordered the adapter Saturday afternoon, nursed my two cans through the weekend and received the product Monday. During that time I began reading all these "horror" stories of people taking hours and even days sometimes to get a can filled only partially most times. Freeze the little one, heat the big one etc etc...

Much simpler and quicker to just release some pressure from the little can as you are filling it just like they do when you fill your bigger tanks duh. Two ways to this. Push down on the pin inside the male connector, but this requires you to remove the bottle and will freeze your hand off pretty quick if your not careful or the easier and way quicker is to use the built in pressure relief valve.

This adapter works on either sized propane tank, if you get the quick fit style you will likely only be able to use the 20# tank so you should get this style because you will not be limited to only one style of tank. Screw it in (backwards threaded) and turn the big tank over, screw in the empty 1# can. Reach under and open the valve on the big tank and you will hear the swooshy sound of the liquid transferring over to the small can....when it stops making noise you will want to pull up on the relief valve with either some bent needle nose pliers or hemostats. It is just a round pin in the hole next to the bottles screw top. I find with the valve at about the ten o'clock position is perfect. You want it higher than lower, you want the liquid in, the pressure out. Just give it little pull, tss tss,until you see it spray out some mist. Maybe one minute per bottle once you get comfortable with the process.

I weigh my empty tanks and then I weigh them when they are filled again. A 1lb tank actually holds 1# of propane. This method will allow me to overfill by about 2.5 oz's, If I am going to use it right away, I won't bother to bleed off the excess, but if I plan to store it I will by either pushing down on the inside pin in the screw top ( at an angle and upright or the relief valve or even the adapter it's self you can take off the big tank, put on the little can by itself and the excess will come right out the other end as you twist it in. be ready to untwist and PLEASE don't try this inside the house.

I am now heating my house for around $1.50 day, @ apx 75 cents per bottle. Paid for itself on the first day. I will be hitting the campground dumpsters this summer to collect me a stash of free empty cans for next winter. I suspect I will buy some of those brass caps with the rubber seals so I will be more comfortable stashing some in the house. Be careful, be smart, do it outside only and just be mindful of what you are doing. My heater just finished up another bottle, so I will swap out bottles, take a shower and go refill my empty one. Boo Yeah!

4.0 out of 5 stars tough handy cost efficient adapter.

Rugged construction and very handy for refilling 1 lb propane bottles for camping gear. Used with other adapters can even refill the small iso-butane canisters for lindel valve stoves and lanterns. Very cost efficient for those appliances. Use a scale and be careful not to overfill any canister. A propane explosion is not pleasant, so get greedy and try to over fill to canister to get more fuel in it. Remember as temperatures rise, so do pressures and iso-butane canisters and quickly become fragmentation grenades if overfilled! Be smart and be safe, weight the empty canister, zero out your scale and then turn the large cylinder upside down to force liquid into the canister your filling. weight the canister after filling to make sure a 1 lb. propane cylinder weighs 1 lb or less. DO NOT OVERFILL ANY CANISTER. If you take an over filled canister into a cabin the warmer temp can raise pressure to dangerous or explosive levels!!!!!!

This item worked great once I figured it out. Mostly you just need to follow the instructions, but there were a couple things not mentioned. First, I didn't find any need to put the empty bottle in the freezer. My bottles filled just fine to full capacity at room temp. Second, you absolutely must not open the valve on the big tank until after it is turned upside down. This is mentioned in the instructions, but not emphasized. I just couldn't get them to fill at all when I opened the valve before I turned the tank upside down. So: use adapter to mate the two cylinders, turn the big cylinder upside down, then open the valve. Next, wait several hours. The little cylinders do NOT refill quickly. It's just a slow process. After about 6 hours, mine are full. I figure this adapter will pay for itself after the first 4 fills.

3.0 out of 5 stars Must remove the pressure lock to work properly
Reviewed in the United States on July 10, 2016

Very frustrated with the item. Tried to refill many times. For a while, it was able to fill a tiny portion into some 1lb cans. Followed all instructions and even froze the bottle for several hours. No luck at all. The most weird thing was that it seems working for semi-empty cans. For those completely emptied, no matter how long I put them in the freezer, it will not refill.

It turned out to be the safety pressure lock. It was intended to avoid overfilling by ensuring some pressure differences. However, it severely restricted the flow especially for empty ones. Just bought another adaptor without safety lock. It worked really well. Within 1 min, all my empty cans were refilled to 70%.

It turned out, this one can be converted to non-pressure protected one easily. Simply unbolt the center pin toward 1 lbs bottle. The small cap in the orifice can be knocked out from the other side using a punch and hammer. There is nothing but a spring and ball to ensure the pressure gap.

The pressure protection is really a bad idea as overfill can still occur. Just make sure the small bottle never exceed nominal fill. It should be all good.
