Parker 20620-4-4 Hydraulic Hose Female Swivel Fitting

Product Description

The PARKER 20620-4-4 is a straight female swivel fitting designed for hydraulic hose assemblies in fluid power systems. Built from steel and featuring a Female JIC threaded connection at 7/16-20, this fitting accepts hose with an inside diameter of 0.188 inches, which corresponds to a 1/4-inch nominal hose diameter (Size 4). The swivel design allows the hose end to rotate during assembly, reducing installation torque and minimizing hose twist. At an overall length of 1.94 inches, the fitting is compact and suited for tight routing applications. Licensed hydraulic system mechanics and industrial maintenance technicians are the typical installers for this type of component.

This fitting is rated for use in hydraulic hose assemblies where a JIC 37-degree flare connection is required at the female threaded end. It belongs to Parker Series 20 and is compatible with a defined set of Parker hose products. Straight-body geometry makes it appropriate for in-line terminations where no angular offset is needed. Applications include mobile equipment hydraulics, industrial machinery, and fluid power plumbing in both OEM and service-replacement contexts.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed down the hydraulic system fully before disconnecting or installing any fittings. Inspect the JIC seat and threads for damage before assembly, and ensure the mating male JIC fitting is clean and free of burrs. Torque to the hose and fitting manufacturer specifications using a calibrated torque wrench, and leak-check the assembly before returning the system to service.
