I have a couple of non-standard butane cylinders that I think I will struggle to swap for Calor ones, not to worry I want to use one as a res for a vacuum pump.
Does the valve just thread into thte top? how do I purge the residual gas - water. carbon monoxiode or just throw a match at it.. he he he
Any ideas on the thread form if it is threaded
Any thoughts on a manual valve for it ?
Thanks

I just fill them with water, to the brim, and drain them off. Then I attak them with angle grinders.

Perfect - thanks.

youd be better purging with nitrogen than using water. theres no way of removing the residual water from the inside of the tank and then vac it out. (steel tank?)
-
Yup - steel tanks.
No nitrogen - cept in the atmosphere but I have a source of air with all the oxygen removed - car exhaust. Mind if the water proves to be a problem I guess I can put the tank on the bonfire for a bit - having purged it and removed the top....

Drop in some dessicant bags? iirc you find them in new trainers, could maybe blag some free from a shoe shop if you pass one?
edited to add, I mean for getting rid of the water not the gas!!

As Butane and Propane are both heavier than air, why not remove the valve( make sure it's empty first!!) and stand it upside down, a few inches off the ground outside for a couple of days, should save messing around with water and having to dry it out.
