Parker 1C977-16-8 Hydraulic Hose Fitting 9000 Psi

Product Description

The PARKER 1C977-16-8 is a straight swivel female hydraulic hose fitting with a metric S 24-degree cone end configuration. Manufactured from steel, it is designed to terminate hydraulic hose assemblies in high-pressure fluid power systems. The fitting accepts a 1/2-inch (8 mm) hose inside diameter and is rated to 9,000 psi maximum working pressure. With an M24x1.5 metric thread and a swivel design, it allows rotational positioning during assembly without twisting the hose. Licensed hydraulic technicians and fluid power specialists install this fitting in industrial, mobile, and off-highway hydraulic circuits.

This fitting is intended for use in straight-run hose assembly applications where a metric threaded female port connection is required. It is compatible with Parker 387 TC ST, 487 TC ST, 787 TC ST, and 797 TC ST hydraulic hose series. The straight body geometry suits installations where hose routing runs axially from the port without requiring an angled adapter. Applications include mobile equipment, construction machinery, industrial hydraulic power units, and other high-pressure fluid systems requiring reliable metric connections.

Key Features

• 9,000 psi maximum working pressure for high-demand hydraulic circuits
• M24x1.5 metric thread for compatibility with metric port configurations
• Swivel body allows hose alignment adjustment without inducing torsional stress
• Steel construction for durability in high-pressure environments
• Conforms to ISO 12151-2-SWS standard

Compatibility

Designed for use with Parker 387 TC ST, 487 TC ST, 787 TC ST, and 797 TC ST hydraulic hose series with a 1/2-inch (8 mm) inside diameter.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic system completely before disassembling or installing any fittings. Inspect thread condition and sealing surfaces prior to assembly, and use appropriate tooling to achieve proper torque without damaging the swivel or cone sealing surfaces. Verify system pressure rating does not exceed the fitting maximum working pressure of 9,000 psi before returning the circuit to service.
