butane bottle to bottle

[jsl2]

I know this subject has been dealt with, so I am sorry for boring you - but I can't find any supplier of butane-nut-to-butane-nut connectors. Suggestions, please. Perhaps I am looking for the wrong thing? I can see POL-to-POL connectors, but they don't look at all right. Or do I just grit my teeth and go over to Flogas?

It's a bit around-the-houses but I do it with a (readily available) POL-POL pigtail and 2x propane-butane-adaptors as below.

Or
Calor 20" Propane/Butane Gas Pigtail Butane Nut x W20

That isn't butane nut to butane nut though, W20 being the regulator fitting

No need to mess about with POL fittings

A Gasboat ( WillHayward) 4017 hose ( M20 fittings each end ) Available in various lengths
and
2x 4012 LH 21.8mm ( butane nut) to M20 adapter will do the job neatly

Thanks everyone. Exactly what I needed to know. Now I just need a set of bathroom scales and a bit of patience.

If the full bottle is upside down does it deliver liquid gas?

Yes. The gas is stored as liquid in the bottle; it's just the same as filling a lighter from a container of gas.
