Parker PP-00556 Sae Code 61 Flange 90 Elbow Fitting

Product Description

The PARKER PP-00556 is a steel hydraulic hose fitting designed as an SAE Code 61 flange head 90-degree elbow. It provides a right-angle transition at the hose end, connecting a 0.75-inch inside-diameter hose to a flanged port using a 3/4-inch threaded interface. This fitting is used in high-pressure hydraulic circuits where routing constraints require a 90-degree bend close to the connection point. It is part of Parker Series 77 and meets ISO 12151-3-E90M-L dimensional standards. Hydraulic technicians and fluid power specialists install this fitting during hose assembly or system repair on mobile and industrial hydraulic equipment.

This fitting is intended for hydraulic hose assemblies where an SAE Code 61 flange port connection is required at a 90-degree angle. Compatible hose series listed by the manufacturer include 387 TC ST, 487 TC ST, 787 TC ST, and 797 TC ST. These hose series are common in mobile equipment, agricultural machinery, and industrial hydraulic systems operating at elevated pressures. The 3/4-inch hose size and threaded connection make it a direct-fit component for those specified hose lines.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and lock out the hydraulic system completely before removing or installing any hose or fitting. Inspect mating flange surfaces and threads for damage or contamination before assembly. Torque to the hose and fitting manufacturer specifications using appropriate hydraulic assembly tools — do not use field-estimated torque values.
