Some time back I asked about an adapter for refilling the 1 lb propane bottles
used for lanterns. Allow me to summarize the responses.
I got 12 responses, three of which highly discourage it due to the danger and
illegality of the practice. Apparently, all canisters currently manufactured are
not designed to be refilled. In fact this is stated on the canister, as is the
DOT-39 NRC 232/290 M1110
Federal Law forbids transportation if refilled -
Penalty up to $500,000 fine and 5 years imprisonment (49 U.S.C. 5124)
Nine other individuals said they re-filled them routinely, but did so a limited
number of times AND were diligent about checking the canisters for leaks (which
seem to be the major problem). Even after leak checks they recommend NOT storing
them in an enclosed space, but I do not do this with the new ones personally
because I have had new canisters leak after removing the attached device (stove
or lantern). Buyer beware.
Anyway, here are the recommended suppliers:
Northern Tool and Equipment
Item # 1764-F717 $15.99
1-800-533-5545 or see their web page at http://northerntool.com
part #g13740 --- $16 each ---
They have an E-Z Propane Filler. Model # LK-51-2325. It fills a one pound bottle
in one minute. cost $16.99.
The standard method to refill is to freeze the canister for a couple hours then
attach it to the 20lb tank and invert. The valve on the 20lb tank is opened
until the hissing stops (about 1 min.), then closed. The canister is then
removed and checked for leaks. Everyone did this operation OUTSIDE and with
great caution, making sure that the connections were all good (as we should when
we connect any propane container to any other item (stove or lantern)).
ONE POINT THAT MUST BE REMEMBERED IS THAT PROPANE IN ANY FORM IS HIGHLY
FLAMMABLE AND A GAS (at normal temperature). I would rank propane MORE dangerous
that gasoline simply because it volatilizes so fast and collects in low spaces.
All our propane containers (1 lb & 20 lb) ride in the BACK of a well ventilated
pick-up truck and are stored in a well ventilated shed. NEVER INSIDE YOUR HOUSE
IN THE BASEMENT.
