Hello,I am searching for orings for my Fx impact and i found almost all on one German web shop ( where i am living for most of the year) but there are no way that I can find this 2:
2,9x1,78 PUR 90
2,84x2,62 PUR 90
I mean i found those but in NBR 90 but not in PUR 90.
Can somebody tell me ist so important for those 2 that they have to be PUR 90 or I can use instead NBR 90.
I know i can order complete set from Uk or USA but from this shop i can order much more for less money.
