Parker BD-11943-1612-1 Hydraulic Hose Fitting 90 Elbow

Product Description

The PARKER BD-11943-1612-1 is a 90-degree elbow hydraulic hose fitting designed for high-pressure hydraulic line assemblies. Built from steel with a threaded SAE connection, this Series 43 fitting accepts hoses with a 0.75-inch inside diameter and uses a 1-inch thread size. It is used to change direction in a hydraulic circuit without bending or stressing the hose. Installation is typically performed by hydraulic system technicians and fluid power mechanics working on mobile equipment, industrial machinery, or stationary power units. The fitting meets ISO 12151-3-E90S-L standards and is compliant with California Proposition 65 disclosure requirements.

This fitting is suited for hydraulic systems requiring a 90-degree directional change at the hose-to-port connection. It is commonly installed in applications where straight adapters would create tight bends or routing conflicts. The 0.75-inch ID matches standard 3/4-inch hose assemblies used across a wide range of industrial and mobile hydraulic circuits. The threaded SAE connection style is a widely used standard in North American hydraulic equipment, making this fitting a practical replacement or new-build component for qualified hydraulic technicians.

Installation Notes

This fitting should be installed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before disconnecting any lines or fittings, and drain residual fluid to prevent spills. Use appropriate wrenching flats and do not over-tighten threaded connections, as this can damage sealing surfaces. Follow applicable fluid power standards and equipment manufacturer torque guidance when completing the assembly.
