Parker BD-1J977-8-8-1 Hydraulic Hose Fitting 0.5 in

Product Description

The PARKER BD-1J977-8-8-1 is a short drop female Seal-Lok swivel 90-degree elbow fitting designed for hydraulic hose assemblies. Machined from steel, it connects to 1/2-inch (0.5-inch ID) hydraulic hose using a 13/16-16 threaded interface with a Seal-Lok face seal configuration. The swivel feature allows the elbow to rotate during installation, reducing hose twist and simplifying routing in tight or angled plumbing runs. This fitting is built to Series 77 specification and conforms to ISO 12151-1-SWES90. It is installed by hydraulic technicians and fluid power mechanics working on mobile or industrial hydraulic systems requiring a compact, leak-resistant elbow transition.

This fitting is intended for use in hydraulic hose assemblies where a 90-degree directional change is required at the hose termination point. It is rated for use with Parker 787TC and 797TC hydraulic hose. The short drop profile keeps the assembly compact, making it well suited for equipment with limited clearance around ports and manifolds. It is commonly found in mobile equipment, industrial machinery, and agricultural hydraulic circuits where threaded face-seal connections are specified for leak-free performance.

Key Features

• Parker Series 77 fitting — compatible with Parker 787TC and 797TC hose

Compatibility

Designed for use with Parker 787TC and 797TC hydraulic hose. Accepts 1/2-inch ID (Hose Size 8) hose with a 13/16-16 threaded Seal-Lok port connection.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit completely before disconnecting or assembling any hose fittings. Inspect the Seal-Lok face seal surface for damage before torquing; a compromised sealing face will result in leakage under pressure. Follow Parker and applicable industry torque guidelines for the thread size — do not over-torque, as this can damage the face seal or fitting body.
