Tight liquid post removal

[Applesnmore]

After some advice please. Have a keg, which is Italian made, ex soft drink. Can remove the gas post but the liquid side is solid. Have tried a 22mm spanner and a box spanner but can't get any movement, difficult to hold keg and apply purchase.

For a stuck nut usually spray wd40 as a penetrating fluid. What food safe materials do folk use to ease stubborn posts and are there any tips to removing stubborn posts?

Many thanks.

A few options:

A little bit of warmth might help soften up any gunk that might be holding - and I mean 60C hot water, not a blow torch that will melt all the o-rings. Put the water in a bucket and dunk the top of the keg in it.

Alternatively if you have a 22mm spanner with a ring end, you can hook something else through the ring end to create a longer lever to use.

An impact wrench is ideal if you can borrow one.

It also helps if you get someone else to hold the keg while you do the wrenching.

Had this before, ended up laying it on the ground between a wall and a lawnmower on the path outside my house, tyre iron slid through the handles to stop it rolling and then stood on the wrench like you would taking out a wheel nut and it opened in one go.

Thank you, I suspect it's been attached with an impact wrench. All my sockets are just for nuts rather than accommodating the length of the post.
Shall try the hot water trick later.

A hair dryer might be a less messy way of heating it gently.

Soak it in cheap cola.. upside down in a bucket for 24hrs

Sit on it long ways down and wack the ring spanner with a hammer

I wouldn't do that. Lots of accidents just waiting to happen in that scenario. Better to add a long bar to the spanner for extra leverage. But warming it would be the best option. The post is probably bound on to the rubber, so softening it should release it.

Where’s the danger? It’s not a propane bottle.

How do you think us spanner monkeys get nuts off? Good luck holding the keg with a 1m extension on.
