Cooking Gas, Purple, Green, Orange, What's The Difference?

[Phil Conners]

I see these different color cooking gas cylinders around, but nobody is able to explain me what's the difference. Anyone know? (Just curious).

[kennedy]

None, just the color. Thais use many colors.

different vendors?

[Phil Conners]

Don't ask me, I don't know, that's why I asked

Yes probably different brands, but is that all? Some places sell (replace) both green and purple tanks, but will not replace for example a purple with a green. The orange I only think I've seen at markets, maybe it's a "pro" or "commercial" edition.

Color denotes origin supplier, some are "inter-changeable" for the re-seller some are not.

Even with Oxygen they just refil their tanks whether they say oxygen or NO2 or whatever. They do not care about the colour codes at all.

I think this is correct, not all the fittings on the top of the bottles are compatible.

Indeed, as I found out the hard way. Bought a new gas-oven and had to buy a new bottle with the appropriate pressure valve and tubing.

After many moves I've somehow ended up with both a green and a purple bottle, and they are certainly interchangeable.

Maybe you should mix the green and Purple gas and see what happens

In the UK the different colours indicated different gases - propane or butane.
