Flame king refillable question

[Baetis62]

Last year I accidentally snapped off that little half moon plastic tab inside the flame king fill valve assembly. It is a fragile little piece.  At first I thought it was just a proprietary thing … lame attempt to prevent refilling the green bombs. Wondering now if that functions as part of the over fill protection or bleeder release when the bottle is full?   Anybody know for certain?

Tight lines!

I cut mine off.its so you can only use fk bottles.i can now fill any prop bottle.i got sick of trying to line that plastic piece with the bottle.

It doesn't affect the filling if your using flame king refill tanks.

I broke mine off before I got the actual refills from them because I used to refill the disposable tanks.

the flame king refill tanks work just fine.

I fill mine up, close the vent screw when gas starts coming out (as per the instructions), then I close vent screw just let if fill up the rest of the way. I end up with close to 2lbs of propane per tank. I am not too concerned about pressure, the flame king tanks are pretty stout and I checked the release valve, there is not too much pressure in tank after filling it that way.

This is NOT the way you are instructed to refill the Flame King tanks so proceed at your own risk.

Does your 2lbs include the weight of the tank, or is that the amount of propane?  I could see a few onces more, but double capacity seems like a lot based solely on volume limitations.

The ring is an o.e.m. fitting and can be removed.
To get max. fill in tanks, put them in the freezer overnight, the condensed air space in the can will allow you to top it of almost full.

If I were to guess, it would be maybe 1.75lbs of propane. I can weigh one when I fill them up this season. I know its definitely not 2lbs of just propane. I get around 8-9 hrs out of a tank on low on my small buddy, with these, I get over 12hrs, enough to run heat me for a full trip and use the rest the next trip.

  I question your math .
a gallon of propane weights 4.24 pounds,a 1 pound cylinder holds a quarter gallon
maximum amount of propane in a one pounder  no matter how you slice it  is 1.06 pounds

If I remember correctly the FK tank empty 1.8 lbs ..after proper refilling  its 2.8 . I think I burned more propane this season then in the past 10 yrs combined . Since getting the FK refillable tanks I no longer worry about the use of propane. If I get cold crank up the heat in my Portable Buddy in my uninsulated two-man Frabill . One of the best investments I have made .

The side of my tanks say TW 1.4lbs, which is tare weight.  WC, weight at capacity, is 2.5lbs.

I completely agree. I love being able to not waste propane and not lug around a 1/4 tank. I have 4 cylinders and I just keep them topped off. I end up carrying less and wasting less.
