With Simply Bearings, you can just take your old O-ring in, and they'll measure it for you and give you a big bag full of O-rings in the exact same size as the original one you provided.

which white O-ring seals?

If you mean the original metal exhaust valve seals, then no they haven't been available for decades??

Or the white/beige urethane buddy bottle O-rings ( BS111 ) sold as 'heavy duty'?
I don't rate them tbh, cost more and don't seal as well as NBR 90.
