Parker PP-00538 Seal-lok Swivel 45 Elbow Fitting -12 Steel

Product Description

The PARKER PP-00538 is a female Seal-Lok swivel 45-degree elbow fitting designed for high-pressure hydraulic hose assemblies. Manufactured from steel, it accepts a -12 hose size with a 0.75-inch hose diameter and is rated to 6,000 psi working pressure. The 45-degree elbow geometry allows for directional routing in tight installations where straight fittings cannot clear adjacent components. This fitting is installed by hydraulic technicians and fluid power specialists assembling or repairing hydraulic lines on mobile equipment, industrial machinery, and related systems. The Seal-Lok design provides a face-seal connection that minimizes leakage risk under sustained pressure and vibration.

The PP-00538 is suited for hydraulic hose assembly work in industrial and mobile equipment applications. It is compatible with a broad range of Parker hose series including 187/TC/ST, 302, 304, 387/TC/ST, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487/TC/ST, 722/TC/ST, 787/TC/ST, 797/TC/ST, and 881 hoses. It is commonly used in construction equipment, agricultural machinery, and industrial hydraulic circuits where reliable, leak-resistant connections are required at routing angles.

Compatibility

Compatible with Parker hose series 187/TC/ST, 302, 304, 387/TC/ST, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487/TC/ST, 722/TC/ST, 787/TC/ST, 797/TC/ST, and 881. Confirm thread engagement and hose crimp specifications against the assembly datasheet before 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 the appropriate crimping equipment and tooling specified for the hose series and fitting combination. Torque the swivel nut to the assembly specification listed in the applicable Parker catalog for this fitting series — do not overtighten or use thread sealant on Seal-Lok face-seal connections.
