   Hi Folks,

Any suggestions of where the best place is to source Orings from?
Specifically the little ones for breech/probe seal for PCP’s.

Thanks,
Pete.

	If you know the size and material then Seal Imports Ltd. There's a branch here in Wgtn, plus another crowd called Pacific seals. I get the feeli ng breech ones are slightly harder. Typical seals are "70" breech might be "90".

	Cool thanks. I know nothing about Orings. Can’t believe I’ve been playing with PCP’s for so long and so far have never needed to change an Oring!

	To measure use OD x thickness of O ring.

	just to clarify pauly's post. it is the OD of the part that the oring goes around you need to measure not the OD of the oring itself. I normally use as a guild .5mm for compression. Another thing to take note is metric v imperial. Metric orings always are 2.0 3.0 4.0 ect...imperial orings are always 2.5 3.5 4.5 ect.. in thickness. so it is best to take the oring off. measure the thickness and the height of the oring and you can work out what it is from there as orings do go out of shape due to the compression they are under.

	Having said all that. You should now know how to identify the type of oring you have. You can now find the size oring you need. You can go here https://deltaflex.com/home/products/seals-%26-o-rings/o-rings and find the size you are after. Then go look at bunnings or mita 10 and have a look at their oring kits they have. if you cant find the size you are after try NZ seal services in onehunga auckland. I used to work there back in the day. I was their service manager. They will have the oring you are after. Edited by nunga - 07 Oct 2024 at 7:58pm

	Thanks Nunga, all good info. The breach of my .22 wildcat is puffing slightly. Still accurate and usable, but I suspect after a few thousand pellets, it’s probably time to replace it anyway. Before I try and dig it out and probably damage it before I can measure it, I’ll try find the correct size on an exploded FX barrel diagram somewhere 🤔 They try source some.

	A tip for replacing it is to get a wooden dowel (5 mm) push it in from muzzle end up to O ring groove, then push O ring in. It'll stop it going past the groove and seat it. And Nunga is quite right, my apologies I always get that wrong. Now let me work on that gun for you.
