Parker BD-1J5431212-1 Seal-lok Swivel 90 Elbow Fitting

Product Description

The PARKER BD-1J5431212-1 is a female Seal-Lok swivel 90-degree elbow hose fitting designed for hydraulic hose assemblies. Built from steel with a threaded connection type, this Series 43 fitting accepts hoses with a 0.75 inch inside diameter and a 3/4 inch thread size. The 90-degree elbow geometry allows routing hydraulic lines in tight spaces or around obstructions without bending the hose itself. Licensed HVAC, plumbing, and fluid-power technicians working on hydraulic systems rely on Seal-Lok fittings for their face-seal design, which provides reliable leak-resistant connections under pressure. Compliant with ISO 12151-1, this fitting is suited for demanding hydraulic service environments.

This fitting is intended for use in hydraulic hose assembly applications where a 90-degree change of direction is required at the hose end. It is compatible with a broad range of Parker hydraulic hoses, including the 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 series hoses in TC and ST configurations. Typical install scenarios include mobile equipment, industrial machinery, and any hydraulic circuit requiring a female Seal-Lok swivel termination at an angled hose end.
