O-ring size for SAE #8 ORB

[Mechanos]

I need to replace the o-rings on a couple of SAE #8 ORB fittings. Can someone tell me the correct dash number of the o-rings for these fittings?

Part # is 568-908. It is not a size found in your common o-ring kit and is 90 durometer, common o-ring kits are 70 durometer.

Is this not the same thing from Discount Hydraulic?

ARP 568 uniform dash no. is -908, inside diameter is 0.644 o-ring thickness of 0.087, hope this helps.

Yes... that is what I was looking for. There is a rubber company here in town that has just about every size of o-ring you can imagine. However, I ended up not needing the specific dimensions. Today, I found a local hydraulic adapter shop that has excellent prices. I was able to pick up some SAE #8 o-rings for ORB fittings for pennies.
