If you need to remove the valve from your 400 or 500 buddy bottle and want to do it without damaging the bottle.....
You need a stauff hydraulic pipe clamp
It grips the bottle tightly without marking the finish and allows you to remove the valve easily
Pipe clamp sizes required
200/280 50mm
400/500 60mm
Thought id pass on this tip
I like this idea 👍
Just tried doing an old 280 with shrader valve .. can't get it to budge even with a little bit of heat
This one
I'm using the clamps in a vice .. with mole grips any advice how to get it off
Cheers
Assuming it has no air left ;D
Grind a couple of flats on the valve and get a spanner on it
failing that cut the 1/4bsp thread off, hammer in a torx bit and use an impact driver..comes free so easily you wonder why you wrecked the valve ???
The early valves can be a pain to remove, they went a bit mad with the loctite.
As you won't be using the valve again you could clamp onto the threaded part tightly with your vice grips then shock it with a hammer, but before that get the valve hot to kill the loctite
At this point...
There is no saving the valve.
So Good Stillson pipe wrench and some heat!
Good Luck,
Stuart
Thanks will give it a go this weekend and report back 👍
2 nuts on the thread to turn the valve & 5-10 mins in a pan of boiling water to heat it through
Hi I read a thread about. Putting the valve in boiling water for a while worked to loosen locktite
I ground some spanner on flats on mine, tightened the spanner up in a vice with the bottle valve in place.
Twisted the bottle off the valve with a boa strap thingy.
Was a doddle.
Make sure the bottle is empty.
I've got a feeling I showed the valve a little heat before doing so with a gas torch.
Hi i know this sounds daft but what way dose it screw off is it Ant clockwise or Clockwise ?cheers ATB . :)
