Flame King Refillable 1LB Empty Propane Cylinder Tank - Reusable - Safe and Legal Refill Option - DOT Compliant-16.4 oz (2-Pack), green (YSN164-2)

Both tanks are leaking. The small o-ring and nylon sleeve fell out of both tanks. i am using the Flame King refill apparatus to fill.Edit: I returned the defective tanks and purchased another pair as I bought the refill valve for flame king tanks. Happy to report the 2 replacment tanks are working great!

Filled these from a 20lb propane tank with the Flame King stand and fill apparatus. Watch a video for how-to and voila! A safe way to have heater or stove bottles on hand always. Tape that hex wrench back on the top so it doesn't get lost.

Fantastic. These ones are legal to refill and saves so much money. I refill them from my 20 lb. tank with the special adapter.

Easy to refill with the relieve valve. Best to weight the empty weight of the tank before refilling as it can be easy to overfill even with the relieve valve.

Great bottles, easy to refill. However the Allen wrenches that come with it and or the set screw are not of great quality and strip easily. No extra set screws come with it. I honestly have no idea if they sell them, or if they can be easily changed out. They seem to be locked in , so the set screw can not be backed all the way out by accident. Which is understandable. So the set screw doesn't become a tiny projectile while filling ; or blowing out with no way to turn off the propane bottle.

I use them with my Flame King heater, and there is a world of difference from refilling throwaway cans. These can threads are brass (not steel), and mate perfectly with the heater brass fittings. Little danger of cross threading (from rough steel threads) and leaks. Also, they don't leak from either valve, when in storage. Refilled throwaways always leave propane scent in storage, after being bubble tested. These do not.................I bought two more of these because I have to use portable propane indoors for heat (Calif utility rates are unbelievable). I now refill them, 8 at a time, because setup takes most of the refill time. Please note that parts subject to leak on these are made of brass, which needs to be sprayed with a soap solution every time.Refilling throw-away cans is only for the foolish. Their orfices are made of steel, that rusts and corrodes. Their steel can is thin gauge, and rusts easily. Please do your homework on this.............I have a lot of Flame King products, and they are quality. They are also overpriced, and a lot cheaper at the mart store. I deducted two stars because it cost me too much.After using them more, and watching videos of cutaways of disposable and Mr Heater tanks, I like Flame King tanks a lot more, and give them 5 stars. It is all about safety, and disposable tanks not only leak with valves intended for short life, but also rust, and have thin walls. Mr Heater is better, but it has a secondary venting pin needed to vent, when refilling; simple is good, and I have no use for idiot-proof extra hardware, when Flame Kings simple Allen wrench does the same job, and is less likely to fail.

Bottles are fine much safer than the green ones that are not safe to re-fill contrary to UTube videos. The hex key can be stored in the plastic cover by drilling a small hole in plastic cover and inserting to keep from getting lost, see picture.

Love the refill bottles
