Valvestem-Oring

[sh0rt]

We had the problem that two of our Newton Kits killed the valvestem-orings. We changed it but didnt glued it in, after some shots it was jumping off....we then took an oring that was a little smaller from my matrix oring-kit. It seals perfect and does not jump off.

The problem i have with it orignial orings is when you need to change them at a tournament and have to glue them in you are screwed.

Is there another solution? Maybe a "real" Valveseal like on the angel valvestem...i think it would be a bit more durable.

I bought some 90 durometer urethane o-rings to try, but have not switched yet.
Anyone else tried this?

Btw the O rings we tried were 009 and 008 from the Matrix kit (black O rings, no urethane).

009 sits tight on one kit, on the other it jumped off after a few shots. 008 wasn't tight enough to withstand a tad more than a case of paint.

Just wanted to throw this information in :)

[Jason W..]

I think you have it backwards. 008 is the smaller ID. Are you sure the larger 009 worked better?

[speedfreakspb]

Yes I am 100% sure buddy.

the 009 worked good on one valve stem, the 008 didn't even stay on the other kit.

Manufacturing tolerances :(
