    Hi
    That is a Gaz 904, this is the full range.

    1262376164-images_other_gas_campingaz.jpg

    They are refillable but the exchange is expensive. The reason a lot of people use them is because they are available everywhere in europe. Unlike other systems which change from country to country.
    They are really more for car camping, motorhomes etc.

    So, you're filling the R904 with the "Asian" butane cans? That's cheaper? Interesting!!

    Hi
    I know ridiculous.
    The worst price wise is the 901 costs £15.00 exchange and only holds 500g of gas.
    Two asian cans nearly fills it for

    Hey Gary that's what you call improvization. Cheap refill right there!

    Well, all this talk of cheap gas has gotten to me, and I am now (pending shipment & receipt) the proud owner of:
    Bayonet-To-Screw_eBay.jpg

    I'll let you all know what it's like and how well (or not) it works when I get it. If it works well, I may try to get a refill adapter for Powermax and CV270/470 type Campingaz canisters.

    "Asian" 230g butane cans are $1.00. Similarly sized Campingaz, Powermax, and standard threaded canisters are all in the $5.00 range.

    I'm after filling a few screw top gas containers with cheap gas you can pick up in the supermarkets.
    Has any one got any links to buying the gear of Ebay?
    I have an idea what I need just need just an expert to point me in the right direction on getting the correct gear.
    Thanks in advance

    Not much I can add.
    Loads of different ways to achieve this now.
    Johns second link shows the best currently available connector for the bayonet cartridges IMHO.
    I still use this method regularly.
    If you can buy a stove like this, cheap you can use the hose for part of your adapter. stove
    Ages since I've looked at this topic, I'd forgotten how people basically called me a liar ](*,) :lol: .
    If you look here cartridge
    The info might help you get the most from your carts.
    If you need any help just let me know.

    Cheers

    Thanks for the links John and Gary and for the offers of help.
    I'll order some bits up and be in touch.
    I was walking around a cheap Camping outlet,Springfields at Hasslingden and could not get over the price of gas cartridges :shock: :shock:
    Thanks again

    Hi Tim. I've not outlined the process on that particular arrangement, but I cut the 'stove' connector of one flexi-hose off and instal the connector from the second hose in that, so you've then a flexi-hose with a screw-fitting control valve at either end. The screw-to-bayonet adaptor then simply screws into one of the valve fittings.

    Here's the way I crimp the connector fitting into the hose

    Hose crimping


    The refilling's done by cooling the receiving screw-fitting cartridge in the freezer for a few minutes (doesn't need to be caked in ice!) and popping the donor, bayonet-fitting cartridge in a jug of hot water (doesn't need to be boiling!)

    Connected up, the raised vapour pressure in the donor cart and the lowered vp in the receiving cart - already low because it's presumably empty or nearly so - ensure the gas transfer is quick (a minute at most). I open one control valve completely and control the gas flow with the other. It's possible to hear the gas flow, even more so if you put an ear to the donor cart.

    To establish how much gas the receiving cart should get, measure its empty weight on kitchen scales, read off the label on it what the net weight should be and measure it part-way through the gas transfer to match up the weight of liquefied gas you've put in with the net weight. That's the scientific way to check on refill charge weight, but in practice, overfilling's not a significant possibility. The warm 'incoming' gas soon raises the heat of the receiving cartridge to room temperature or above and a equilibrium of vapour pressure in donor and receiving cartridges results, the gas transfer slowing to an (audible, ear up against cartridge) trickle. When that's happened, I've always found that the recharge is near enough the specified net weight.

    John

    Hi Tim/John
    Not wanting to but in here but if you buy a length of threaded studding like this.
    You can cut a bit off and drill down the centre (pillar drill would do) and use this to join the two S9 hose assemblys using an o ring.
    That way you haven't altered the hoses in any way.

    Hey thanks, Gary, I can see that'd work. It'd be one O-ring for each end of the stud and presumably a blob of Araldite or Locktite to stop the joint from unscrewing.

    Cheers,

    John

    The way I did it was to make the stud short enough for the two hose ends to but up against each other. The o ring was just pushed over the stud so it was sandwiched between the two. I was going to use a flat piece of nitrile with a hole in but tried an O ring first and it worked so just stayed with that. I haven't had to lock it with anything but I may have just been lucky.

    hi all, first thread that popped up for "gas refill"

    when i bought my soto stormbreaker, like many modern multifuel stoves, it came with a mountaineering propane/butane gas can adapter that could plug into the burner fuel line
    soto2.jpg soto3.jpg

    for a long time i've used the much cheaper butane cans for; table home cooking, motorcycle touring and hiking

    so i've been looking for a way to run the soto burners on butane cans, the first cheap chinese adapter bought is poorly designed and doesn't fit onto the soto blend can mount, i might be able to lathe it down but it's a pain

    so i also bought a very cheap and tiny gas transfer adapter to allow cheap butane to flow into almost empty blend cans that the soto stand is designed for

    frustratingly it ALSO didn't fit the cans correctly due to either poor design or manufacture
    IMG_20231215_090830.jpg

    fortunately it has been easy to find and fix the problem by taking the tiny adapter apart and running a 4mm drill down the middle so the 4mm tip of the butane can is able to reach and seal on the internal o-ring
    IMG_20231215_090840.jpg IMG_20231215_090920.jpg IMG_20231215_091027.jpg

    once that was done the cans could pushed together and you could hear the warm butane flowing most of its contents into the frozen blend can

    pics of the recently refilled blend powering the muka burner, (generator tube cleaned out and new o-rings fitted)
