Parker BD-1J74312-10-1 Hydraulic Hose Fitting 45 Elbow

Product Description

The PARKER BD-1J74312-10-1 is a 45-degree elbow hydraulic hose fitting designed for use in high-pressure fluid conveyance systems. Built from steel with a Seal-Lok end connection, this fitting provides a reliable, leak-resistant interface between hydraulic hose and equipment ports. It is sized for a 0.625-inch (5/8-inch) inside diameter hose in the size 10 designation, with a 3/4-inch threaded connection. The Seal-Lok design uses a face-seal mechanism that reduces the risk of leakage common with tapered thread fittings. Hydraulic technicians and fluid power specialists install this fitting during hose assembly or system maintenance across industrial and mobile hydraulic applications.

This fitting is suited for mobile hydraulic equipment, industrial machinery, and fluid power systems where a 45-degree elbow routing is required to manage hose bend radius or to clear obstructions. The threaded connection type allows for field assembly with standard hydraulic fitting tools. It is compatible with a wide range of Parker hose series and is appropriate for both OEM builds and aftermarket hose replacement in shop or field environments.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic system completely before removing or installing any fittings. Use appropriate hydraulic fitting tools and follow the Seal-Lok face-seal assembly procedure; do not over-tighten or substitute thread sealants not rated for hydraulic service. Verify hose and fitting compatibility and confirm the system has been bled and inspected for leaks before returning to service.
