Pardini SP Oring
I just took apart my SP bolt to replace the O rings for the first time. I've never had the bolt apart. There are 11 rings. I've read that there are 13…. Any ideas? I am positive that I didn't lose any. Interestingly the diagram at Pardini shows 14…..

Maybe your gun was assembled on a Wednesday? The 11th, rather than on Friday, the 13th.
Sorry, no help at all, but I could not resist

Sir the last 2 must still be in the gun! If it only has 11 then there would be a huge gap between the black buffer and the stack of o- rings!
One good thing is if you took out 11 and put 11 new ones back in it’s going to be ok.
Call Alex today and ask him
Did you insert a small Allen wrench all the way in the bolt

Oh really? They look black in the pic. Well good mine was clear and hard and when stacked next to 13 new ones the old stack was noticeably shorterorpheoet wrote:Nope.

Re: Pardini SP Oring
Has anyone taken said O rings to an industrial supply and
found a direct replacement??
I doubt Pardini had their own rings molded and would guess
you can purchase a 100 bag for the same price as they will charge
for 13-14 of them.
A durometer gage should tell if the rings are neoprene or viton.
I expect neoprene as there is no high heat exposure requirement.

Try a search. Somebody already posted a McMaster-Carr substitute that is really inexpensive.

Re: Pardini SP Oring
As noted above:
Mc Master Carr O rings:
Part number 5308T113, Buna-N, Durometer Hardness (90A), 0.07” Width, 0.070” ID, 0.201” OD
I've been using them in my 22 LR unit for almost a year and the wear cycle and functionality seems to be the same as the factory o rings so far. think I have 5K on my current set. I have not tried them yet on my 32 ACP unit since that is not shot as much as my 22 unit.

I tried ordering o rings from McMaster but since I live in Canada they don’t want to ship them over here.Any chance you would send them to me in a small envelope? It would be greatly appreciated.
I would need 26 rings, for my .22 and .32 cal.
I tried locating them here in Canada but without success.
Thank you
