Parker BD-11743-12-8-1 Hydraulic Hose Fitting 45 Elbow

Product Description

The PARKER BD-11743-12-8-1 is a steel 45-degree elbow hose fitting designed for hydraulic system assemblies. It connects hydraulic hoses to ports or components at a 45-degree angle, reducing hose stress and improving routing clearance in tight installations. The fitting features a 0.5 inch inside diameter, a 3/4 inch threaded SAE connection, and is built from steel for durability under hydraulic system pressures. It belongs to Parker Series 43 and meets ISO 12151-3-E45S-L standards. Licensed hydraulic system technicians and industrial maintenance professionals handle installation in mobile and stationary hydraulic applications.

This fitting is used in hydraulic hose assemblies where a 45-degree offset is required at the hose termination point. It is compatible with a wide range of Parker hose series, making it a practical replacement or assembly fitting for both mobile equipment and industrial hydraulic systems. Typical installation scenarios include construction equipment, agricultural machinery, and industrial power units where hose routing geometry demands an angled connection rather than a straight fitting.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with hose assembly practices and applicable system pressure ratings. Depressurize and lock out the hydraulic system completely before removing or installing any fittings. Use calibrated torque tooling appropriate to the thread size and fitting material to avoid galling or undertightening. Verify hose and fitting compatibility by confirming hose series and inside diameter before final assembly.
