filling butane cylinder

This is going to be a certified adventure, Peter. You might find yourself cutting the red rubber hose in half, putting a US fitting and regulator on the end to adapt to the US propane tank you might have to buy. Sounds like you are on your way to an Adventure™. Welcome to US! Hope you have a great time on our side of the pond.

Propane btu per gal @60deg 21548 butane 21221, btu per cuft propane 2488 butane 3280, max flame temp in air propane 3595 Deg F butane 3615. Butane is hotter but has a higher boiling point propane -44deg f butane 15 deg f. Due to boil point you are not going to find butane north of the mason dixion line if then. If this is a full time move convert to Propane and buy a DOT approved tank,Your stove should run on propane but you may need to adjust air to the burners to get a good flame consult the manufacturer of the stove. Most if not all LP dealers are going to look at your tank and say they can not fill it do to liabilty (this is the world we live in)
Good Luck

Butane and Propane are the same thing. The difference is Butane is for warmer climates as its boiling temp is higher. Propane is for colder climates. Filling with Propane will not cause any problems in the USA. Doug

Odds are you can use propane instead of butane, Very slight difference in the amount of heat produced, major difference is the vapor temp, Where as butane is not much use when the temps drop below freezing, Propane is good to about minus forty.. But in this country, it is not uncommon for greedy dealers to sell butane as propane in the south, less you get real cold, you will never know the difference.. Should work both ways. (Butane is less expensive you see so the dealer pockets the extra profit when he sells Butane at propane prices).

Hello Peter,
I think that it will be very difficult to refill your Campingaz 907 butane canister in the United States. However the smaller Campingaz disposable "Valve Cartridges" like the CV-470 Plus are available in camping supply stores across the whole country.

I think that you should be able to purchase an adapter in Germany like this one so that you can use the small Campingaz canisters.

There are two REI Stores very close to Baltimore that should have canisters of Butane.

Note that the adapter shown in your picture is called a "POL" and it is commonly used for filling Propane cylinders in the US (sometimes we have a propane/butane mixture), but we do not use it for only butane.

Cheers,

Propane burns at lower temperature (I think), but you can always turn the regulator higher, if needed. I converted my backpacking Primus stove to accept green Coleman 1-pound propane canisters because they are cheaper and easier to find. Any hardware store in the US and most stores in Mexico, Central America and Caribbean will have green Coleman propane canisters, or sometimes - long blue canisters with same propane - those are used for welding.

The fuel in Primus or MSR canisters is a mix of butane, isobutane and propane. Green and blue propane canisters are pure propane. No problems with running Primus stove on propane. The only strange thing is that the propane canister makes clicking sounds from time to time and then flame flickers, as if something is boiling inside the canister or in the hose :)

Check into converting to propane. I would research on some sailing forums to see what others have to convert to propane. Because that is the only way I see it. I think you only have to change orifice because one runs so much hotter than other, forget which one is hotter. But I understand getting the orifice is hard sometimes.
The only reason I know that much is because of a conversation with the dryer folks back when we thinking about changing the house natural gas to propane and he told me of the sailing crowd.

Here is one but very old...http://www.sailnet.com/forums/gear-maintenance/11656-butane-propane-conversion.html

I'm not sure, but I guess that all RV stoves are good for propane.

Do you think I need a different regulator? My GOK EN61 should work with propane or butane at a pressure of max 16 bar = 232 psi

I think you will have trouble finding butane in the U.S. specially in northern areas. I can find no supplier in the Baltimore area for Butane. Is the stove rated for propane? If so buying a small propane cylinder on arrival with a propane regulator may do the trick.

You can buy a portable portable propane stove upon arrival, and a 20-pound cylinder in the closest Walmart. And rubber hose with adapter for 20-pound cylinder (those stoves are usually made for a small 1-pound cylinder). Total cost ~$150, with full cylinder. Or don't buy 20-pound cylinder and adapter, and use disposable 1-pound cylinders instead. 1 pound lasts one week.
