gass suplyers in the uk

[eggs]

and i assumed r290 would be abit purer, than the stuff youed get from b&q, what about the nitrogen though, i dont realy want to pressure test on propane.

(forum lack of edit button ftl)

From what i gather there is more gas in a cheap throw away fag (cigarette to our cousins across the pond) lighter ,than there is in a domestic fridge. Call it Butane or R600, it's the same stuff.

I wonder if all those lighters get pressure tested with nitrogen?
I am certain my lighter left on the dash of the van in summer withholds far greater pressures than a domestic fridge/freezer in normal operation.
