CP250 canisters adaptor for Cadac

[jimmywease]

Has anyone successfully run a Cadac from a cheapo CP250 canister?

For shorter trips, I am trying to facilitate leaving my 907 cylinder at home, in favour of canisters.

Until now, I was using a Campingaz Camping Chef, plus a Cadac Safari Chef 2 LP. They were connected to the 907, via a quick-release splitter, thus allowing one or both appliances to be connected.

To replace the Camping Chef, I bought a Bistro2 type single stove and CP250 canisters. To run the Cadac from canisters, I purchased the Cadac regulator:

Cadac Threaded Cartridge Regulator QR | Cadac UK

Negating the need to have a bulky gas cylinder, the Threaded Cartridge Regulator with QR connection is the perfect lightweight alternative for picnics, camping and trips to the beach. Enabling low pressure appliances to operate off EN417 gas cartridges, just simply screw onto the cartridge...

cadacuk.com

All well and good, except this means I need two types of canisters on board: the cheapo CP250 for the Bistro and the C500 for the Cadac.

Luckily amazon is awash with cheap adaptors, to convert a CP250 for use with C500 type fittings:



Sadly, the recess in the amazon adaptor is 22mm dia while the Cadac regulator seems to be 23mm dia, so they won’t connect.

Anyone found an adaptor out there, that fits?

You can run the cadac off of the threaded en417 type gas cans quite easily. They come in all different sizes and infuse one for my jetboil when out walking. I do this using a different regulator. As you say. Iit saves on taking the 907 out or using your spare 907

Yes, but I was hoping to dispense with the en417 cans, In favour of the cheaper and more widely available CP 250 cans, as I already have to hav in favour of the cheaper and more widely available Campingaz CP250 cans, using an adaptor. That way I would only need one type of can, for both the Cadac and the Bistro.

The adapter I already purchased is slightly the wrong size for the Cadac regulator:

My question is: Has anyone found an adapter that will fit the Cadac regulator?

You can refill EN417 canisters but you do so at your own risk.

Thanks for that advice, but refilling canisters is not going to be the answer. I’m trying to save space, time and money.

My question is specifically about whether a Cadac can be fuelled by a Campingaz CP250 Canister, as these are cheap, widely available and are the same canister as my other stove.

Yes, I could understand it if there was a suggestion that it takes more than one cheapo CP250 can to power a Cadac. Instead, they advertise the fact that one can is sufficient, but don’t offer a simple one-canister adaptor.

I’m mystified!

You can’t get much cheaper than these 0.227kg EN417 canisters at £3.85 a kilo of gas compared with £6 a kilo for CP250

This link appears to be for a cheap version of the Campingaz CP250 canister, with the same bayonet fitting. This is the type that I want to use for my Cadac, but can’t find an adaptor to fit.

The two different fittings are ‘bayonet’ or ‘threaded’. At the moment, I need to carry bayonet cans for my Bistro2 and threaded cans for my Cadac. The threaded cans are less widely available, more expensive and more bulky.

Those canisters are en417 threaded like this (not bayonet).

@jimmywease , see if any of these work - https://mercatorgear.com/product-category/kovea-gas-canister-adapters/ . Sorry, not read the complete thread to determine your needs correctly/completely.

I thought those were en417 sorry: you’d need one of these to convert then.

Jimmywease, thank you for raising this thread. I bought one of those adapters because, like you, I wanted to use the cheaper CP250 cartridges on a cadac regulator. I hadn't tried it up until now, because I still have a few en417 bottles. Just been out to try it and the adapter doesn't attach to the Cadac regulator as you point out!

Please post back if you find an adapter that does work. Or a regulator that attaches directly to the CP250 cartridges. Cheers.

Thanks. Will do. Just back from a sunny week in Brighton UNTIL it rained continuously throughout this morning’s decamp!

Will do. It’s becoming a bit of a quest but I’ll let you know if something fits.

I did consider getting a friend to use a lathe, to open out the aperture in the adaptor by 1mm. But then I thought again. Using an adaptor is already a bit of a bodge. Two bodges might make a gas explosion!

Don't be worried about gas leaks as that aperture does not have a role to play in stopping gas flow and hence no gas leak can occur.

The bottom part that attaches to the canister is the one that needs to fit snug - which you are not messing around with.

The top part is the screw cap in which the part that will attach to this will have a rubber gasket to direct gasl flow.

The first time you mentioned this, my thought was also for machining the aperture to make the part fit. Unless someone finds a correct fitting part, that may be the best option. It is aluminium and you could even increase the aperture with a Dremel with steady hands.

 

[jimmywease]

I’m going to have to admit defeat on this one and continue to pack two types of canister, for the Bistro2 and the SafariChef. My handy friend came back with concerns over my plan to get the adaptor to fit:

“Hmm, I took a look at the parts and I am a bit concerned. I can probably do the machining but the adaptor external part is threaded all the way to the end. Looking at the regulator, there is an internal o-ring that should bear against the adaptor forming a gas seal. The end of the threaded part of the adaptor should be machined to bear against the o-ring. I am concerned that if I machine as requested it will leak .. lots
I could try machining the threaded part flat but I have no specification as to the degree of compression required for the o-ring. Too much or too little and we are in the leaking gas / bomb zone”

 

[jimmywease]

Speaking of gas bombs, here’s a video to demonstrate the perils of inadvertently overheating the canister, by using an over-sized pan on the Bistro2 type stove.

Apparently some Butane canisters now come with a safety pressure-release system, called CRV (countersink release vent), which reduces the explosion to a manageably awful fire. If you bulk-buy 28 cans, they’re still pretty cheap:

I think the choice is either the Cadac Trio Power Pak or switch to en417 stove as well. We have a Primus Mimer that works a treat. I have to say though that the LP Cadac is not very powerful when using with the en417. Maybe that’s why the Trio Pak uses 3 canisters to boost the power. If so, the economic gains may not be as good as you would expect.

 

[a892374923874]

I bought the Trio pak but returned it because you shouldn't leave the canisters in it connected up to the regulator, and you can't leave them in there loose. So you have to take them out which means pak + canisters take up double the space.

I've resorted to the duo pak because I feel safe leaving the en417 canisters connected up to the regulator.

Could you not simply get hold of another Bistro or similar and cannibalise the canister fitting then use some O clips to attach to the Cadac hose?

 

[Eber123]

We decided to get a small BBQ for the camper. So we looked into this to see what is on the market. To make a long story short we decided to go for the Cadac Safari 2.

My problem was that I am not that familiar with all the gas connection, so I looked it up. Wow, there are so many. But, of course, we wanted to ensure that we get gas cylinders in the countries we plan to travel in. So which was the most widely spread connection?

The gas cylinder based on the EN417 seems to be the one that is widely available in Europe. But the EN417 does not necessarily describe the valve / connection (so I believe based on my research). The connection the cylinder need to have is the "Lindal Valve".

I believe that this is a kind of adapter that could help to use the smaller and cheaper gas cartridges.



But I am not 100% sure. I still look into it.

Regards,
Eberhard

I did consider this, since the Bistro2 type stoves are almost as cheap as adaptors. The awkward thing is that the cartridge housing includes a mechanism that pushes the canister base into the connection. Again, any workaround would be a bit of a bodge, so I’m happy to throw in the towel and use EN417 Lindal Valve Threaded type canisters for the Cadac. I don’t think I could bear the withering look from my wife, as my hair caught fire from leaking gas!
