Parker PP-00220 Hydraulic Hose Swivel Fitting 1/4 in Steel

Product Description

The PARKER PP-00220 is a straight swivel fitting designed for use with hydraulic hose assemblies in fluid power systems. Machined from steel, this fitting features a 1/4 inch (0.25 inch) inside diameter and an NPSM threaded connection at 1/8-27 thread size. The straight swivel design allows the hose end to rotate freely during assembly, reducing torsional stress on the hose and making tight installations easier to complete. Overall length measures 1.69 inches. It is installed by hydraulic technicians and industrial maintenance professionals working on mobile equipment, industrial machinery, and fluid transfer systems.

This swivel fitting is suited for medium-pressure hydraulic hose installations where a straight, threaded NPSM connection is required. The 0.25 inch ID corresponds to a hose size 4 designation. Compatible hose series listed by the manufacturer include 187, TC, ST, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 hoses. This fitting is typically used in both stationary and mobile hydraulic circuits where hose routing requires swivel capability at the termination point.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system assembly practices. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Use appropriate wrenches on the fitting flats only — do not grip the swivel body in a manner that could damage the swivel mechanism. Follow applicable industry standards for hydraulic fitting torque and assembly procedures as outlined by the system manufacturer or recognized fluid power standards.
