For a 1.50 inch SAE O-Ring Boss straight thread fitting or adapter, this is the direct-fit replacement seal. It’s the Hercules 568-924 (also shown as C1CL37, MI-08748177, or MINO-00407X88007) and measures 1.72 inch ID, 1.956 inch OD, with a 0.118 inch cross section.

Will this O-ring hold up alright in a hydraulic system running around 2000 PSI?
Question by: Merle S on Jul 24, 2025, 7:36 PM
With a 90 durometer rating, this Buna-N O-ring is designed to resist extrusion under pressure, making it a good choice for hydraulic fitting applications where dimensional stability is important.
