O ring size

[RBAZ]

Can someone tell me the size of o rings used in the foster quick disconnect fitting?

The female Foster uses a -010. 90 durometer will give the best longevity, same for polyurethane.

Is that a 010 x .90 size? U.S or metric, know nothing about how they are sized.

"Dash" sizes denote imperial / inch sizes (technically the AS568 standard).
