Parker PP-00253 Hydraulic Hose Swivel Fitting 0.375 in

Product Description

The PARKER PP-00253 is a straight swivel fitting designed for hydraulic hose assemblies. It connects hose ends to hydraulic system ports using a metric threaded interface, allowing the hose to rotate freely and reduce torsional stress during assembly and service. Built from steel, the fitting accepts a 3/8 inch (0.375 inch ID) hose and uses an M18x1.5 metric thread. Overall length is 2.23 inches (57 mm). This is a Series 43 fitting and is installed by hydraulic system technicians and fluid power specialists working on mobile or industrial hydraulic circuits.

This fitting is suited for hydraulic hose assemblies in both mobile and stationary equipment applications. It is designed for use with hose sizes designated as 6 mm in Parker metric hose sizing. Compatible hose series listed by Parker include the 187, TC, and ST series, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 hose families. The straight configuration suits inline connections where hose orientation requires rotational freedom to prevent twist during installation.

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. Use appropriate torque per the system specification for M18x1.5 metric threads and confirm fitting orientation before final assembly to avoid hose routing issues. Inspect threads and sealing surfaces for damage before installation.
