An SAE ORB (O-Ring Boss) fitting is a type of hydraulic fitting defined by the Society of Automotive Engineers (SAE) standard, which uses a straight-thread design with an O-ring to create a secure, leak-proof seal. These fittings are commonly used in hydraulic systems for high-pressure applications. The O-ring sits in a groove on the male end and compresses against the flat face of the female port to prevent fluid leakage.
