Lrp x20 oring snapping

[Lee24h]

Running lrp x20 stock spec and the oring keeps snapping under full boost
I have gone through three and put a heavier duty slightly thicker oring and it seems fine but why are the originals snapping

[PaulRotheram]

What O-ring are you referring to?

[Lee24h]

The one on the end of the rotor before the front bearing

[Matt Butcher]

very strange! I have afew x20's and x12's and have never had an issue with the o-ring, is there a sharp face on the bearing or rotor causing it to eat into the o-ring?

[Lee24h]

It wont occur on a x12 as it used shims no oring

[Matt Butcher]

X12s do have a o-ring also ;-)

We'll all mine have.
