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

I am calling today....

Keep us posted!

So the diagram shows 14, many say 13, mine had 11, and there’s a Pardini video in Italian that shows 10....

Update. My .32 bolt has 13

Bingo and they are still black so I would wipe them off and reuse them

Nope. Clear and hard.

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 shorter

What picture? The pic above is a screen shot of the Pardini video where he removes 10 rings and replaces with 10 rings.

My bad I thought that was from you

Take a q tip with some Clp and clean out the 3 tubes in the bolt the black on my bench it what came out . Must be the black coating

Curious where you found the last 2?

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.

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.

Mr. Mark your o rings are in the mail

John, If you still have some orings available I’ll take some. Thank you.
