Spare o-rings for O ring face seal fittings

[hosspuller]

When I take a hydraulic fitting apart, good practice says to replace the o-ring. Where can I find the various size and durometer for 1/2 and 3/4 inch fittings? Then I can purchase the rings in bulk, rather than an expensive kit with sizes I'll never use.

Thanks for any help...

JJ thanks .... I've been to similar sites. I'm looking for a cross over to standard or "trade size"

Then, we'd be able to buy in bulk ... A package of (50) trade size #018 1/16" 3/4 ID is $1.50 at Fastenal..

Another question ... Are these face seal "o" rings fractional or metric?
