SEAFLO Pump - O-Rings?

Question

Looking for a replacement o-ring for the intake and discharge fittings on a SeaFlo #41 12v water pump. I don't have the measurements of the old o-rings, they fell apart as soon as I started messing with them.

The ID is close to 1/2", and the OD is at least 25/32" ... I have tried a 9/16" x 23/32" o-ring and it is not big enough. I have tried a 9/16" by 15/16" o-ring and it is too big.

Suggestions?

take the pump off head for ace hard ware ,or call the factory.

Manufacturer only sells the o-ring with replacement fittings, won't disclose the size. So that means it's probably custom?

Maybe try metric sizes?Otherwise the fittings are cheap enough:  https://www.amazon.com/SEAFLO-MNPT-Elbow-Fitting-Ring/dp/B072W29ZKL
