Parker PS810503-8-8 Male Orb Jic Swivel Fitting 1/2in 5000psi

Product Description

The PARKER PS810503-8-8 is a straight inline hydraulic hose fitting designed to connect male SAE O-Ring Boss (ORB) straight thread to a male JIC 37-degree flare swivel. Built from steel, this fitting handles hydraulic circuits operating up to 5,000 psi, making it suitable for demanding industrial and mobile hydraulic applications. It measures 3.09 inches in overall length with a 1/2-inch body diameter and a 3/4-16 thread size. The swivel design on the JIC end allows for easier hose routing and reduces stress on the connection during assembly and service. It is installed by hydraulic technicians and fluid power mechanics working on hose assemblies, manifolds, and cylinder circuits.

This fitting is used in hydraulic systems where an ORB port on a pump, valve, cylinder, or manifold block must be connected to a JIC-terminated hose assembly. The inline straight configuration suits applications where hose and port axes are aligned. Typical environments include industrial machinery, construction equipment, agricultural equipment, and mobile hydraulic systems. The 1/2-inch hose size and 5,000 psi rating cover a broad range of medium- to high-pressure hydraulic circuits commonly found in these fields.

Key Features

• 3/4-16 thread size compatible with standard SAE O-Ring Boss port specifications

Compatibility

Designed as a direct-fit hydraulic hose fitting for 1/2-inch hose assemblies terminating in a JIC 37-degree flare swivel end, connecting to male SAE O-Ring Boss straight thread ports rated for up to 5,000 psi. Part of the Parker PS series of hydraulic fittings.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. Inspect the O-ring seating surface and JIC flare for damage before assembly, and use only a properly seated, undamaged O-ring on the ORB thread end. Tighten fittings to the fitting manufacturer's specified torque guidelines using appropriate hydraulic fitting wrenches — do not use pipe wrenches on flare or ORB connections.
