SAE ORB fittings are widely used in hydraulic systems to create secure, leak-proof connections between components, suitable for high-pressure applications in industries like automotive, aerospace, and agriculture.

SAE ORB fittings incorporate an O-ring seated in a groove on the male fitting. When connected, the O-ring compresses against the female threaded part, forming a tight seal that prevents fluid leakage.

These fittings are commonly manufactured from steel, stainless steel, or brass, depending on the application’s requirements for strength, corrosion resistance, and compatibility with hydraulic fluids.

Yes, SAE ORB fittings can be reused as long as the O-ring and the fitting itself are not damaged. It is recommended to inspect and possibly replace the O-ring to maintain a secure seal.

SAE ORB fittings are available in a variety of sizes, typically ranging from -2 (1/8″) to -32 (2″), allowing for their use in different hydraulic systems and applications.

Installation generally requires standard hand tools for tightening. However, it’s important to use torque wrenches to avoid over-tightening, which can damage the O-ring.

Choosing the right material such as stainless steel or applying protective finishes like zinc plating can help prevent corrosion, especially in harsh environments.

The pressure rating can vary depending on the fitting’s size and material, but generally, these fittings are suitable for high-pressure applications, often capable of handling up to several thousand psi.

The O-ring must match the specifications of the fitting, typically defined by its material and dimensions. It’s crucial to consult the manufacturer’s specifications or a compatibility chart to select the appropriate O-ring.

Common failure modes include O-ring damage due to improper installation or material degradation, thread stripping from over-tightening, and corrosion-related failures.
