Parker BD-1J0431212-1 Male Orfs Swivel Fitting 0.75 in

Product Description

The PARKER BD-1J0431212-1 is a male ORFS (O-Ring Face Seal) swivel fitting designed for hydraulic hose assemblies. Built from steel with a Seal-Lok shaft type, it provides a leak-resistant threaded connection at a 3/4 inch thread size for hoses with a 0.75 inch inside diameter. The straight profile and swivel design allow technicians to orient the fitting during installation without stressing the hose. With an overall length of 2.9 inches, it is suited for tight routing situations in mobile and industrial hydraulic systems. Hydraulic technicians and fluid power specialists are the primary installers of this fitting.

This fitting is rated for use in hydraulic hose assemblies where an ORFS swivel connection is required. The straight configuration makes it a common choice for inline hose terminations on mobile equipment, construction machinery, agricultural implements, and industrial hydraulic circuits. It is compatible with Parker hose series including 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 hoses across TC and ST configurations. The 12 mm hose size designation corresponds to the 3/4 inch inside diameter classification under SAE standards.

Compatibility

Designed for use with Parker 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 hose series (TC and ST configurations) with a 3/4 inch inside diameter and 12 mm hose size designation.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed the hydraulic system fully before removing or installing any fittings to prevent injury from pressurized fluid. Inspect the O-ring face seal surface for nicks or debris before assembly, and ensure the O-ring is properly seated to achieve a leak-free connection. Follow SAE J516 torque guidelines for ORFS fittings of this thread size when making final connections.
