Avid exlixr R bleed port o-ring size?

[02GF74]

As per title, anyone know the size of the o-ring used in Avid exlixr R bleed port reservoir? (I think the bleed screw is M5)

Failing that, an e-mail for SRAM.

thanx.

Any shop worth there salt should have them in stock, failing that you could contact fisher outdoor leisure who deal with all avid stuff though thay may not deal direct but point you in the direction of a dealer, which bleed port caliper and lever o rings are different sizes.
