Parker BD-139771212-1 Female Jic Swivel 90 Elbow 3/4 in

Product Description

The PARKER BD-139771212-1 is a female JIC swivel 90-degree elbow fitting designed for use in hydraulic hose assemblies. It connects to 3/4-inch (0.75-inch) inside-diameter hose and uses a 1-1/16-12 threaded connection. Constructed from steel, this fitting is built for the pressure and vibration demands common in mobile hydraulic and industrial fluid power systems. The swivel design allows for easier routing and torque-free assembly when connecting hose ends. Licensed hydraulic technicians and fluid power specialists are the typical installers for this type of fitting.

This fitting is designed for use with Parker 787TC and 797TC hose and belongs to Parker Series 77. The 90-degree elbow configuration is suited for installations where hose routing must change direction sharply, such as tight-clearance hydraulic circuits on mobile equipment, agricultural machinery, or industrial power units. The female JIC swivel end provides a reliable, leak-resistant connection when properly torqued to the mating male JIC port.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed down the hydraulic system fully before removing or installing any fittings. Use appropriate flare-seat torque values per the fitting manufacturer specifications and relevant NFPA or SAE standards for JIC connections. Do not over-torque the swivel nut, as this can damage the 37-degree flare seat and result in leaks.
