SAE (Society of Automotive Engineers) fittings and ORB (O-Ring Boss) fittings are both types of hydraulic fittings, but they differ primarily in their sealing methods and applications. SAE fittings typically use a 45-degree flare or a straight thread with an O-ring for sealing, making them versatile for various automotive and industrial applications. In contrast, ORB fittings use a straight thread with an O-ring in a recessed groove to create a leak-proof seal, often preferred in high-pressure hydraulic systems due to their reliable sealing capability.
