I have a cylinder with an A-clamp. It has a removable fitting. I have just tried t remove it and it won't budge! Any ideas? Also, should I remove the o-ring first? Thanks!

bit more force needed!

make sure you're using the correct allen key, then either use a ring spanner on it for extra leverage or some other object you have lying around that will extend the length of the allen key.
with a spanner / wrench attached to the allen key, close to where it goes into the insert, you can gently tap the spanner / wrench with a hammer to break the hold. once it's been loosened it's simple to remove.

if the thread is corroded, use a small wire brush to clean the thread and make sure there are no wire filaments left after doing this - they'll spoil your day if they sit on the o-ring.

**don't** spray release oil onto it (WD40 etc)

o-ring will make no difference as there's a captured 2nd one on the hidden face of the insert and the insert is not under pressure anyway (unless in use of course!).

Try pouring boiling hot water over pillar valve then use allen key as quick as possible.

just to are trying to remove the DIN plug insert from the pillar valve and not the pillar valve itself?
