Attaching black attachments and undoing them from corny leg

[JockyBrewer]

The issues with this I've had in the past have been remedied by lubricating the post o-rings.

Otherwise just make sure you pull the disconnect collar up before pushing it down on the post.

If its too tough then something is wrong!

Innmy experience, grey disconnects fit both posts, black only the one without notches.
As well as silicone spray, sanitiser works well from a spray bottle I find

I think I have two gars inlet posts. Just tried a grey on it and goes on nicely.

I’ve experienced this and decided the cause was the little black moulding that sits on the spring and has the o ring fitted is fractionally too long and bottoms out before locking on. Filed a little bit (technical term) off the tip to fix.

I tried a grey one and it goes on fine. Probably both posts are the same inlet type.

The grey disconnect fits both as the gas post is slightly larger. If the black disconnect is connected to the gas post , it takes a fair bit of pulling to remove it. I use green and red O rings on the keg posts . G for Gas , G for green and G for Grey . So the grey disconnect goes on the gas post which has a green O ring . It saves a lot of messing when I'm hooking them up. Some second hand kegs have faulty posts fitted or they've had a hard life and picked up a few knocks over their lives if you can identify the keg , you could pick up a replacement liquid post . There's a lot of different brands and they're not all interchangeable. It can be difficult to remove the posts as stainless on stainless can cause galling , in other words they can bind todether. You may need to shock the spanner with a hammer to get them separated.
Apologies for repeating the last two previous posts we were all typing together at the same time

Yep. Tried the grey on it and it works fine. I’ll just use grey in future. The corny has a mark fir in and out so I can differentiate that way. Cheersc

Gas posts have small notches around the post, if you can't see them then you can feel them with your fingernail, liquid posts don't have these notches, easiest way to tell them apart.

It would be interesting to see if taking the centre pin from a grey connector that fits the post and transferring it to a black connector that doesn’t fit to see if it fixes the problem.
