I would try nose pliers.To remove,one jaw pushing against the opening of the clip the other on the top of the valve.To replace,holding the nose pliers vertically one end of the jaw to the valve ,the other to the clip to push the clip in place.

Hello:
Preferably for a silicone one.
It should not be removed until you have taken out the valve or you will lose the plunger inside.
And that will stay that way till you open the boiler to fish it out. 8^/.
Just a question of manual dexterity and some patience.
BUT ...
From what I can see, to take off the valve (obviously with the machine cold and unplugged ) you will need a long tube wrench the size of the nut you see at the bottom.
Try maybe a spark plug removal tool?
Seems the same or approximate size.
Check with the machine's OEM or dealer about the size if the spark plug removal tool does not work.
Rinse, inspect and repeat if necessary till it is clean.
Then change the 'o'ring, reassemble and refit on the boiler.
Let us know how it went.
Cheers,
CIV

That clip keeps the valve plunger from diving inside the boiler.slipchuck wrote: ... but it has this tiny clip.

You can pull it out the retainer ring and get it back in place with a pair of pliers, no big deal.slipchuck wrote: How do I remove and replace it?

Thanks
Is there a gasket that goes between the boiler and the valve?
No matter how much pipe tape I put on it won't stop leaking when it's up to pressure!
It looks like it might have been one there but it was so worn out it's hard to tell

I recently did the same job, cleaning was enough to revive the vac valve on my Urania. From what I found, but I did not search too long as I needed to take the valve out to see what dimensions it has, there are only a few variants and mostly 1/2" and 3/8". If the threading matches thread tape ought to be enough, but apparently not in your case. Does the thread match?

Yes they match and screw in well

too much thread tape can work against you too, 2-3 windings in the right direction should be enough

BTW: I managed to lose the circlip and replaced it with some shrink tube, my vac valve sits horizontally so it works well enough to secure the stem.

Hello:
A photo of the valve and catch-cup as they were when off the boiler would be helpful.
Unless I am mistaken (apart from the teflon pipe tape) if there was a gasket it would have been between the catch-cup and the boiler and not between the valve and the catch cup.
Like this:
|||
|||
=== <--- valve
|||
| | <--- catch-cup
|_____|
******** <--- gasket
=========== <--- boiler body/valve catch-cup seat
I can't get the ASCII symbols above centered on the same axis, but you get the idea.
Check to see that the valve catch-cup seat is clean and maybe try a teflon/EPDM or even red fiber washer the same size as the valve thread.
Please post photos to illustrate what you are doing.
Cheers,
CIV
