Inlet: 3/8” Flare Fitting Male QCC (ACME) Fitting: 16.4 oz (1 lb.) Propane Tank Fitting Material: Brass Description: - Save Money and Reduce Waste by Refilling! - Made to Last with Hight Quality Brass - Air Tight Fittings for a Secure Connection - Useful in Emergency Situations! - Ready for Use Right Out of the Box Review: Order of operations is key. Great value for the cost! - Fantastic help during the recent snow event!! Great product. Refilling the smaller 4 pack of 1lb tanks even 1 time makes this pay for itself. Some lessons learned from our first uses - because common sense sometimes takes a few tries :) Step 1. Make sure the larger propane tank valve is shut off! Step 2. Screw in the large end of the adaptor into the 20lb propane tank and hand tighten. Step 3. Screw in the 1lb tank you intend to refill to the smaller adapter side and hand tighten. *You can weigh your canisters before and after filling, compare it to a new full tank, and bleed off any excess if needed.* Step 4. Turn on the larger propane tank valve, and refill your 1 lb tank. DO NOT OVER FILL. Step 5. TURN OFF the larger propane tank valve. Step 6. Unscrew the smaller 1lb tank FIRST. Step 7. Only then should you unscrew the large end adapter, and remove it from the larger 20 lb propane tank. Bleeding off excess propane = If you unscrew the large tank first, while the 1 lb tank is still screwed in, the 1 lb tank will immediately begin to release all of its propane. There are youtube videos that show this process from end to end, but it would have been nice to have them on a printed card in the package at the time. But overall, great packaging and product was the perfect size and worked fantastically in a pinch. I'm ordering another one. One for my permanent emergency supplies and one for the camping boxes. Review: Worked as it should with no headaches - Had the Black one years ago and it Worked fine a few times, no issues, then sold it. Years later then tried the Mr Hearer brand variety, and it always leaked one gust of propane out every time attaching it and required pliers, and the valve on my standard tank went bad and could no longer be refilled at the refilling stations, and I blame the Mr Heater brand one for breaking it. So I ordered a 2 pack of the red ones this time, 1 looked a little scuffed up in the threads as if it was used, and the other 1 looked fine so I used it, and on the first fill it worked perfectly, nice and full fill, no pliers, no leaks, no issues. Excellent device, I only needed 1 anyway and the 2 pack was the price of 1 anyway. I like how it does not insert inside the standard tank like the Mr Heater ones do. In the past I remember the black one did not fill my green bottles very well, and the Mr heater one did better in that regard, but this new two pack of red ones I got, they filled the green bottle I filled just as full as the Mr heater brand one was able to get them. Without doing any funny business techniques you hear/read about, they get about 2/3 full. I have tried putting the green bottles in the freezer 30 minutes prior to refilling them and it helps a little more go in, but not enough to go to the trouble. I would estimate you only get maybe an extra 1/6 fill by putting them in the freezer. I mean, if you're already leaving your standard tank out in the sun heating up anyway it's the same deal, as long as your green bottles are in the shade. ## Features - ✓ propane adapter that saves money - Gas one's propane refill adapters allows you to refill your traditional green 1lb propane tanks with the fuel from standard 20lb propane tanks.

A tank does not need to be 100% empty to refill it. I have a similar adapter where the instructions suggest putting the tank in the freezer for an hour before filling to get more in (as well as having the BBQ tank warm, perhaps in the sun). Then to fill the small one you connect up the adapter to the big tank first, screw on the small tank second, flip the big tank upside-down, then open the valve on the big tank where you should hear liquid propane flowing into the small one for about 1 minute. Then reverse that order to disconnect (close big tank valve, upright it, unscrew small tank and remove adapter). There are reasons for that order like if you connect the small tank to the adapter first, gas may be squirting out of it while you try to get it on the big tank (but that won't happen doing the order said). On any propane tank you only want it filled 80% of the actual capacity so there's room for the gas to expand even if out in the hot sun (as well as let the liquid vaporize since you want gas vapors to run most things, not liquid propane). I saw another person suggesting "You want to get all vapors purged out of the tank while filling" but then he had a tank deform like it was about to explode after he'd filled it. That was likely caused by his OVERFILLING it since as I said you only want 80% filled (not the "purge ALL vapors out"). So after you fill them shake it and see if there's some room left since you do want some space. If it feels rock hard like it is 100% full, then you may want to reconnect it to the big tank keeping the big tank upright and open it's valve to let some gas go back into it for 30 seconds, then close the big tank valve and unscrew the small tank again. **Q: I have a small heater with hose that runs off a 1lb tank but want to connect to a 20 lb tank. Will this work as an adapter? No refilling** A: No, this adapter connects a 20 lb tank to a 1 lb tank, both ends are female connectors. You will need an adapter with a female 20 lb connector and a male 1 lb connector. This hose should work: https://www.amazon.com/KIBOW-Connector-Appliances-Refillable-Cylinder-4Ft/dp/B072FS1BSL/ref=sr_1_fkmrnull_1?keywords=KIBOW+Type+1%28QCC+1%29+Propane+Tank+Hose+Adapter%2FConnects+1LB+Propane+Tank+Connector+Appliances+to+a+Refillable+Bulk+Propane+Cylinder-4Ft+Long&qid=1550336562&s=lawn-garden&sr=1-1-fkmrnull Or this adapter should work: https://www.amazon.com/Mr-Heater-Bulk-Adapter-Fitting/dp/B0050EFIIU/ref=pd_sbs_263_44?_encoding=UTF8&pd_rd_i=B0050EFIIU&pd_rd_r=67e43239-320e-11e9-a6c1-83a6775f2fe5&pd_rd_w=GxgnR&pd_rd_wg=HJo0o&pf_rd_p=588939de-d3f8-42f1-a3d8-d556eae5797d&pf_rd_r=AJKRFZCK308S4EPEA64X&psc=1&refRID=AJKRFZCK308S4EPEA64X Ort you can search for 1lb to 20lb propane adapter, or check with a propane gas company like Blossman. **Q: Ours did not come with directions. Are directions available?** A: It’s against most local laws to refill 1lb tanks, so just youtube the instructions **Q: I bought 2 and neither works. No matter how tight the black ring, it won't seal. Gas and liquid leaks. 2 different tanks.** A: All Propane tanks have a built in safety devices to prevent leakage at the adaptor connections. There will be no gas flow if connections are not properly seated. If your tanks are leaking they should be examined by professionals or exchanged, They might be older versions that do not comply with newer safety requirements. Either the tanks are faulty or there is some other problem that needs correcting ASAP ## Customer Reviews ### ⭐⭐⭐⭐⭐ Order of operations is key.

Here's the science, without math. When a tank is half full, half the contents are liquid (LP=liquid propane) and half are gas. The liquid turns to gas until a certain gas pressure is reached inside, equalibrium. Opening the valve lets gas out, reducing pressure in the tank causing more fuel to turn from liquid to gas as fast as you use it. When you burn all the fuel, the gas pressure inside becomes that of air, well below that of a tank still having liquid inside. An empty little tank will partially fill from an upside down big tank, because the little tank's gas pressure is lower than the big tank's pressure. But, as soon as some liquid gets into the small tank, it starts to turn to gas because the little tank's pressure is low. For all gases, PV=nRT where nR is a constant and thus Pressure times Volume is proportional to Temperature. When you put your little tank in the freezer, you lower the temperature without changing the volume (i.e tank size) so the pressure must go down. If the small tank was empty to start with, the pressure was already low, that of air, and now it becomes less than air. If the little tank wasn't quite empty, its pressure starts high and goes down some, but not as much as if it were empty. Connecting the big tank to the little tank, you want the little tank to have as little pressure as possible. It is thus best if it emptied and then chilled. The big tank's liquid is at the bottom when it is inverted. The big tank pressure is higher than the empty and/or cold small tank, so liquid goes from the big to small until both tanks are at the same gas pressure. The little tank's pressure goes up as liquid transferred to it turns to gas while the volume for that gas is being reduced by the entering liquid's volume. Because it is chilled, that pressure is not as high as in the big tank. At some point, the little tank's pressure reaches the big tank pressure and liquid stops transferring. With regards to overfilling a small tank, the physics seem to indicate that is not possible, but there's a catch, so keep reading. Here's what might be happening. The small tank is chilled and then mostly filled with liquid, leaving just a bit of space for the non-liquid gas. The two tanks are equal pressure so the small one is fully pressurized. It gets disconnected and then starts to warm up. Remember, PV=nRT. With the volume constant, when the temperature goes up, the pressure must go up. Since it was at full pressure when it was cold, it is now over pressurized and thus could cause tank bulging. Without doing the math, it's not clear how much overpressurization will occur. There are a lot of variables here, like how hot was the liquid from the big tank and how long filling took and how much warming of the small tank occurred during filling. Some reviewers suggest poking the valve with an Allen wrench to let the gas out to fill with more liquid. It will reduce pressure temporarily or overpressurization as it warms. After you poke it you need to quickly reattach it. Now, back to the catch about overfilling. If your stove runs with the tank not fully upright but the tank is 99% full, what will come out? Liquid. Will it turn to gas before it gets to the burner and what will happen if it doesn't? I don't know and don't want to find out firsthand. Best to use the scale and let some out if you've overdone it. ## Frequently Bought Together - GasOne 50180 Refill Adapter for 1lb Propane Tanks & Fits 20lb Tanks, Black - Masterbuilt Portable Propane Gas Grill with Folding Legs, Chrome-Coated Warming Rack and 288 Cooking Square Inches in Stainless Steel, Model MB20030819 - SHINESTAR Propane Hose Adapter & 5 FT Braided Hose for Buddy Heaters, Coleman Stoves, Blackstone 17" 22" Tabletop Griddle, Char-Broil Portable Grills, Weber Q Grills- Converts 1 lb to 20 lb Cylinders --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/62271007-gasone-50180-refill-adapter-for-1lb-propane-tanks-and-fits](https://www.desertcart.tn/products/62271007-gasone-50180-refill-adapter-for-1lb-propane-tanks-and-fits) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-19*
