Parker BD-1JS4312-10-1 Female Seal-lok Swivel Hose Fitting

Product Description

The PARKER BD-1JS4312-10-1 is a female Seal-Lok swivel short hydraulic hose fitting designed for high-pressure fluid conveyance systems. Built from steel with a threaded connection type and straight shape, this fitting accepts hoses with a 0.625-inch inside diameter (hose size 10) and uses a 3/4-inch thread size. The Seal-Lok interface provides a face-seal connection that reduces leak points compared to conventional flare or compression fittings. It is installed by hydraulic technicians and fluid power specialists working on mobile equipment, industrial machinery, and related hydraulic circuits.

This fitting is engineered for use in straight-run hose assembly configurations where a swivel short end is required to ease routing and reduce assembly torque. The Seal-Lok face-seal design is well suited for medium- to high-pressure hydraulic applications where fluid cleanliness and leak-free performance are critical. It is a Series 43 fitting rated for use with a wide range of Parker hose series including 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 hoses in TC and ST configurations.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and fully isolate the hydraulic circuit before removing or installing any fittings. Ensure mating surfaces are clean and free of debris before assembly, as the Seal-Lok face-seal design depends on surface condition for leak-free performance. Follow the hydraulic system manufacturer and applicable industry guidelines for assembly procedures and system re-pressurization.
