Parker PP-00389 Hydraulic Hose Swivel Fitting 3/8 Inch

Product Description

The PARKER PP-00389 is a steel swivel fitting designed for hydraulic hose assemblies. It uses a Seal-Lok face seal connection to provide a leak-resistant joint at the thread interface, making it suitable for high-pressure hydraulic lines where reliable fluid containment is critical. The fitting accepts a 3/8-inch hose diameter and threads to a 13/16-16 port. Licensed hydraulic technicians and fluid power specialists install this type of fitting when assembling or servicing hydraulic circuits on mobile equipment, industrial machinery, and related systems.

This swivel fitting is suited for hydraulic systems requiring a rotatable end connection that allows the hose to be positioned without twisting. The 13/16-16 thread size and Seal-Lok configuration are common in Parker hydraulic hose assembly applications. The swivel design reduces stress on the hose at the fitting junction during installation and during normal system operation, which is particularly useful in tight routing environments found on construction equipment, agricultural machinery, and industrial power units.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the face seal surface and O-ring for damage before assembly, and ensure threads are clean and free of debris. Torque to fitting manufacturer specifications using a calibrated torque wrench and a backup wrench on the mating port to prevent port distortion.
