Parker BD-1JS43-10-8-1 Female Seal-lok Swivel Fitting

Product Description

The PARKER BD-1JS43-10-8-1 is a female Seal-Lok swivel short fitting designed for hydraulic hose assemblies. Built from steel with a straight shape and threaded connection type, this Series 43 fitting accepts a 1/2-inch (hose size 8) inside diameter hose and provides a reliable swivel interface for routing hydraulic lines under pressure. The overall length is 2.89 inches (73 mm). It is installed by hydraulic technicians and fluid-power mechanics in industrial and mobile hydraulic systems where leak-free, face-seal connections are required.

This fitting is suited for use in hydraulic systems that use Parker hose series including 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 hoses in TC and ST configurations. The swivel design allows the hose end to rotate during installation, reducing torque buildup and simplifying assembly in tight or angled routing applications. Typical installations are found in both stationary industrial equipment and mobile hydraulic machinery.

Key Features

• Female Seal-Lok swivel interface provides a face-seal connection that resists leakage under dynamic hydraulic pressure
• Straight shape simplifies in-line hose terminations and direct port connections
• Steel construction provides durability in demanding hydraulic service environments
• Swivel design reduces hose twist during assembly and allows repositioning after installation
• Threaded connection type for secure, repeatable make-up
• Conforms to ISO 12151-1 face-seal fitting standards

Compatibility

Designed for use with Parker hose series 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 in TC and ST configurations with a 1/2-inch hose inside diameter (hose size 8).

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and drain the hydraulic circuit fully before removing or installing any fittings. Inspect the sealing face and O-ring seat for damage before assembly, as face-seal connections rely on clean, undamaged seating surfaces to prevent leaks. Torque to the fitting manufacturer's published specification for the thread size; do not rely on feel alone for Seal-Lok connections.
