Did yours come with spares? Also if you have your old plenum you can use that one for now until you get some others.

Hi Glem.chally.
I think is not matching from the old plenum .I tried it and is huge. Michal is using a different size. I emailed him before few min.
Thanks for your advice before few days.Finally the leak beside the power wheel was from this oring as you mentioned.
I managed to fix successfully the regulator and to reseal all the gun but I cant install the fx power plenum .Is impossible to fit inside the action clamp.I lube it I tried gently but nothing.
Is not fitting inside even without the orimgs .
The only possible solution I can think is with a special tool to try to open a little bit the clamp but again I hesitate because If I scratch the bore between the clamp I will destroy all the action.If I don't manage it I will wait news for the Poland oring size and I will replace it back .
My priority now is to learn about the oring size of the Poland pp.I tried 2-3 possible dimensions but I have leaks.
Thank you again

Haha you called him Michelle (a womans name). Thanks for posting, I did ask a member what size they were and they thought the same size as the mk2 plenum but yeah I have some and they seem too big.
*Ah it's the same oring as the C3 bumper in earlier MK2, and I definitely suggest the PUR variant because it seals against a moving part so it needs that abrasion resistance.
Grease it liberally and the valve rod it seals in the plenum.
Thanks again Chris!

Yeah you can use it, PUR means polyurethane and it's more resistant to abrasion. The NBR will work for a while but eventually a "flap" will tear from the inner part of the oring will tear and it'll leak like you have now.
It seals against the valve rod that moves slightly during every shot so that abrasion resistance comes in handy.
I've put a PUR one in and its been good for a long time now. But if you can only get nbr it'll work. Silicone grease everything on assembly.
PM me your address I have a couple I'll mail you one if you like.

Thanks Glem.
It was a headache in my country to find all the required sizes of nbr 90.Only in nbr 70 big availability.
I made a list and I have place an order from a European site including nbr 90 and pur as well all from 50 pieces.
I am trying to avoid same problems in the future.
Since day one a have a huge collection from all impact orings but unfortunately all are nbr 70.....
