PMI regulator removal

[Liam92]

looking to remove the reg from my PMI 4500 tank, just wondering if its possible to do this at home or if i need to send it to you guys to get it off?

This is something i have never had to do so not too comfortable in my knowledge of these sort of things, how do i reattach the reg once i have the bottle back? (this is for taking the bottle onto a flight)

I would say put the reg in a vice with wood shims so not to damage the reg. Get a rubber strap wrench and secure round the tank and undo. It will depend on how hard it is to undo if pmi put loctite on the reg threads. To put the reg back on just do the same.

If your unsure or can't get it off let someone else do it that is experienced in these matters.

The most important thing is make sure there's no air in the bottle first.

If the reg is not loctited on it is a simple matter of unscrewing it. But it's probably loctited on and that means you'll have to soften the loctite before making any attempt to remove the reg. Or send it off to get it removed.

Hey,

You can check with the airline, a few I have used in the past did not care as long as it was not under pressure, ie filled.

Otherwise, dump the fill and wrap a rubber strap wrench around the bottle. Wrap a towel around the reg and unscrew.

The loctite, if present, is usually easily broken.

I have seen folk put a 10mm ring spanner on the fill valve to give you some extra leverage too..

yeah its pretty well loctited in. heard a few ways of loosening this up, but i'm assuming the hairdryer will be the best way? after that brute strength should get the job done

i held it over a boiling kettle, then got bored so poured the water into a dish and put the reg in.

i wasnt to bothered about the reg tho

 

[Liam92]

my worry about the boiling water is that since theres no pressure the fill nipple will let the water in right through the reg =\

edit: ignore, never read the 'not bothered about reg' bit

or just put a cover on it
