Mr. Heater Propane Refill Kit for Fuel Keg 1 lb. / 16 oz. Refillable Propane Tank

Very happy with this product. If you live in CA, this is a must if you use 1lb propane bottles as they are being phased out. This product makes this fairly easy to fill these 1lb tanks, but it's best to READ THE DIRECTIONS to optimize filling. Or, you can be like me and weigh your empty refillable tank and the re-weigh to ensure your tank is completely filled. Although this product is not unique, the combination of this product and their own refillable tanks makes this process as easy as it can be. Please be sure to follow all (commonsense) safety processes as propane does escape during the filling process.Overall, I recommend this product. Note, I do recommend this product with the manufacturers refillable bottles.

The fuel savings alone will more than pay for the initial investment for everything you need to use these refillable bottles!

It is simple to use and seems to work well. The instructions are not overly helpful, but they get you close enough.

I love this! If you frequently use disposable 1 Lb propane bottles this will save you money, time, and keep some disposables out of the landfill. The ring on the bleeder valve makes this so easy for me. I also bought the flame king refill kit but it requires the use of an Allen wrench to open & close the bleeder valve. I've only got a half a finger on my left hand so the fuel keg is much easier to operate. I really liked that the flame king kit came with a stand. The clamp on feet that come with the fuel keg kit require you to lift the propane tank on to a suitable surface like a workbench or tailgate. I deducted 1 star for the clamp on feet & 1 of the fuel kegs had a bad bleeder valve rendering it useless.

This works very well with the Mr Heater fuel kegs (only). Quick and easy filling at less than $1 per fill, with no wasteful disposable cylinders to place in the landfill. Also the Fuel Kegs are DOT compliant for transport. What’s not to like?

I've only used it once, to fill 3 Fuel Kegs, but it worked as advertised. I filled from a full 20 lb tank. It filled each of my three 1 lb Fuel Kegs in about 1 min and 17 sec. To get a sense for how much propane is lost from the vent valve (which is kept open during the fill, per instructions), I weighed my 20 lb tank before and after with a digital luggage scale (which I've found to be accurate in that it matched the airline scale). Filling 3 tanks used about 3.3 lbs from the 20 lb tank (so about 1.1 lb to fill a keg). Weighing the tank a 2nd time showed 3.2 lbs used (so the venting loss might be less than 0.1 lbs per Fuel Keg).I weighed my 3 Fuel Kegs before and after filling. They all weighed between 1.9 and 2 lbs empty. The first one I filled weighed 0.9 lbs more after filling (but I stopped filling within a couple seconds after the white mist appeared from the vent). The second and third kegs weighed exactly 1 lb heavier after filling (I filled them a bit longer, waiting for the mist to be more continuous before ending the fill).After removing the Fuel Kegs from the fill apparatus , I made sure each retained its plastic sleeve and o-ring (as other reviews have noted that these can get stuck to the filll nozzle). I also used a brass cap with rubber seal (purchased separately) instead of the pastic cap that comes with the fuel keg. I figure this is an added safe guard in case the Fuel Keg leaks.I tested one of the filled kegs in a "Big Buddy" heater. It fit just fine (allowing the heater door to close) and worked (on low, medium, and high).I got this setup for emergency prep, since I have several of the Buddy indoor-safe propane heaters (in case we can't run our furnace). So I likely won't be able to comment on how it holds up under frequent use, but I'm very satisfied for my purposes. The Fuel Keg seems sturdy and well-constructed.

Already had the el cheapo adapter but when I saw this I opted for safety first. Easy to use & safe. Stop buying one pound cylinders and start refilling.

excellent investment for anyone using 1kg fuel bottles. The build quality is solid, and the kit works flawlessly, allowing for quick and efficient refills without leaks.One of the best parts is the cost savings—refilling your own propane bottles is significantly cheaper than constantly buying single-use ones. Over time, this kit pays for itself while also reducing waste. If you use 1kg propane regularly, this is a must-have tool for you.
