Tuning MK2 Power Plenum orings?

[bigHUN]

I am noticing some wear on the white "oring thingy" (B25.2) inside PP End Cap,

I remember I could not find anywhere this white PUR90 oring, but in my eyes look more like a sleeve or bushing and most likely some teflon material (or silicon or similar ?? ). Or there are two pieces of B25.2 inside?

I have a same size oring (B25.2) in NBR90 a full bag. Would that rubber work over a prolonged time and under heavy load ?

Last year I made the peek valve poppet and I remember high polishing the long valve rod for a purpose of minimizing any friction between parts, but still that white oring shows some signs I don't like.

If I could pull the original out in a decent way...

It seals on a moving part I'd get the PUR ones. McMaster and Carr has some maybe someone in the USA will relay you some.

Thanks, I sent an email to Travis if he can give me some from he's Service kit. Also emailed oringsandmore to advise for material.

For now I will just leave it there inside a pocket, tomorrow a friend of my will rework the peek valve poppet on a lathe.

{This was my mistake designing the OD 9.1 mm instead of 8.1 mm. I would never notice a difference if I would stay with pellets, but just recently I converted the Impact to shooting slugs and here it shows for first time that the air path is restricted.}

I got every o-ring for the impact MK2 PP except that one from Orings and more. That one he said he never carried and doesn’t have it. If you find a source for it let us know.

While I’m ordering from McMaster, anyone know the part number for the Impact MK2 PP AMP regulator Belleville spring washers. With $22+ in shipping need to make the order worth it?

I removed them, deburr the ID and OD, polish these edges, IPA wash and put the same back. I don't think anything is wrong with the washers. I had a stupid scba fill ones somewhere in the hottest summer and a lot of moisture got into the system and it was full of mud.

Did the polish the edges while I was chasing a leak between the bottle and regulator. Through Oringsandmore I have already purchased 5 or 10 of each Oring in the impact MK2 PP. just don’t to pay $22+ in shipping for just one bag of 5 PUR90 orings so just thought I’d grab the Belleville washers at the same time.
