Funny you should say that. I'm more qualified as an engineer than for IT.

Thanks Munsey, I'll be heading over that direction later so will have a looksie.
Its worked for me many times. If you a bit of research on the internet you will find that this is the way that most if not all do it.
Think about how you refill a 'refilable lighter', you plug in the nozle then flip up-side down and press to enable the transfer of liquid. Same principal here.
bivouac have some small MSR ones
Seems everyone sells them at roughly the $10 mark for the 110g MSR. The 230g version is only $6.50 at Mitre10. Go figure. :cave:
It's all good advice Mauser. I appreciate the warning. There's good reason why NZ don't sell them, they tend to treat everyone to be as stupid as the most stupid f&@k which is one way of dealing with things. If treated correctly I believe these units are safe. I agree using the weight to fill. If I suddenly stop participating in this conversation ignore everything I've said [emoji44]
Your local mega or hardware store will probably carry replacement lpg bottle connectors. Simply cut off n replace. Make sure your fittings are tight afterwards.
Remember that leaking lpg liquid will "burn" your skin as severely as the flame will. Gloves and goggles are minimum I'd say. And well ventilated too. LPG is heavier than air I think. If I'm correct it'll mean It can accumulate in low areas.
Having said all that I've bought one too and will be trying it out when I get back from this weekend's wallaby trip
Vietnamcan is right. I took the first few turns of the thread off with a bench grinder because the thread is not quite right and can't wind in enough to lock in. Also remove the rubber washer off the fitting that goes into the 9kg as it stops it getting in far enough. It still seals perfectly without leaks. Remember I'm not responsible if you do some numbnuts job and fry yourself.

I had an old regulator lying around that was faulty and id replaced, i cut the end off it to get the screw in piece, and you are able to screw apart the new adapter hose, and remove the fitting and replace it with the fitting i took off the old regulator.
There is some thread locker on the threads of the brass fittings on the adaptor hose, i needed to apply some gentle heat from gas torch to release it, then it came apart nicely.
So is the adapter that was linked the wrong thread or are they all the wrong thread? Or hit and miss?
What about the canisters themselves? Are they designed to be refilled? Will they fatigue and fail? How many refills might be considered safe? (If any)
I would think that only the seals in the valve would be liable to perish from the longer use than as designed, other than internal corrosion I wouldn't think the canister would fail, have ordered a couple for gifts
Makes a deafening sound when I sit down too quickly.
Mind you I'll need to buy new gas bottles very shortly and then they probably wont fit.
What a great idea. Always hated the idea of taking 2 cylinders on a walk just because I couldn't be positive of how much remained in the first one. Ill be ordering one or two myself.
Cheers
just picked up a few 250g cans from mitre10 mega, cost about $6 ea (not much more than wholesale price)...... hardly worth the risk of my face sluffing off over being a $6 tight arse.
If you use a remote canisiter and can invert it then you'll get the most out of it. But yeah the "how long will a half full can last? " question will still be there. unless you can weigh them?
The lightweight hiking guys in the US are getting 20-22 1liter full rolling boils using the remote burners/windscreen/Heat exhanger pots and 250g cans.

Pretty reasonable pricing on these too, while still being really light. full set up including a full 250g can is about 500g.

yeah mine doesn't fit, ordered it from the aliexpress link provided
The MSR cans I use have marks on the side which show how full the can is when floating in water.
My motivation for refilling my own canisters was not a "tight arse" move but more a way to reduce the amount of waste that is caused by the "disposable" nature most of our gear is these days. I can only imagine the many partial empty canisters clogging up the ever-growing landfills in this world, or even worse biffed in the bush as it was "dead weight" for the walk out... 1 step at a time.
Often see 2 or 3 or even 4 all but empty cans left in a hut...
Nobody wants your empty gas cans.
Carry them out ya lazy cunts you are not doing anyone a favor.

Ditto, And i can't keep collecting partially emptied gas canisters,
Just watch what you buy on Aliexpress, don't expect to get a refund if a package arrives with a poorly manufactured, rusty paperweight that slightly resembles the object in the photos.
I've now been burnt so going to stick to Ebay and Amazon as much as possible
Just a couple of .22 scope mounts, were covered in rust on all of the steel parts, threads were stripped on half of the screws and the scope tubes part was so poorly finished the 2 halves wouldn't even close up.
Also got an airsoft scope mount for a friend of a friend from different seller, same thing.
Both partial refund requests were rejected, and they made me take heaps od photos and videos.
I just don't think aliexpress is cheap enough for the minimal buyer protection it offers
I am going to buy that cooker as having it stand on the ground independantly of the gas can is much more stable. I tried the 28g micro cooker (screws to the top of the gas can) but it's just too lightweight for a big billy. I wasn't aware of the heat exchanger billy so thanks for posting that.
Bought 3 100g jetboil canisters from Macpac today, $6.45, the cheapest ive seen in a while for that size. Will have a go at the refilling thing.
Macpac have been running a special on the 100g, they were 5.81... I 've seen various 110g at Bunnings, plenty of places have the smaller cans... I've found the JetBoil to be better for my JetBoil, mix seems to be slightly different than Kovea, and the others...
My 2 adaptors arrived today, have taken 1,2 and 3 turns off the thread and taken off the rubber seal, mine still leaks gas out around the fitting. Do i need to take more thread off to screw it in further?
Yep must not be tightening up inside the female fitting of the cylinder.
Hmm..
Funny you should say that... Ive just had 3 wks in the Arctic Circle using a Jetboil on Jetboil branded gas.
Couldnt find a mix on the can, but Google says its 80% isobutane, 20% propane - so a normal mix
It was the BEST can Ive ever used!
Got 29 boils out of the 230gm can (tally on bottom) and left it behind with a mate with prob 7-10 left in it
Was left in the snow and on frozen ground most of the time.
FWIW
Brunton/Kovea: 0% n-butane, 70% isobutane, 30% propane
Coleman: 60% n-butane, 0% isobutane, 40% propane
Primus: 70% n-butane, 10% isobutane, 20% propane
MSR IsoPro: 0% n-butane, 80% isobutane, 20% propane
JetPower (Jetboil): 0% n-butane, 80% isobutane, 20% propane
60/40 to 70/30 is normal mix for lpg
It's normal (n) butane IIRC
