Parker BD-1JS771212-1 Female Seal-lok Swivel Hose Fitting

Product Description

The PARKER BD-1JS771212-1 is a female Seal-Lok swivel short hydraulic hose fitting designed for use with high-pressure hydraulic hose assemblies. Built from steel, this straight fitting features a 0.75 inch inside diameter and a 1-3/16-12 threaded connection. The Seal-Lok interface provides a leak-resistant face seal connection, reducing reliance on thread sealants and minimizing leak points in hydraulic systems. It belongs to Parker Series 77 and is intended for use in industrial and mobile hydraulic circuits. Licensed hydraulic technicians and fluid power specialists install this type of fitting during hose fabrication and hydraulic line routing in equipment and machinery applications.

This fitting is suited for hydraulic hose assembly work in both mobile and stationary industrial equipment where a swivel short female Seal-Lok end is required. The straight configuration supports inline routing without directional adapters. Per the supplier specifications, this fitting is compatible with Parker 787TC and 797TC hose. The ISO 12151-1-SWSB standard governs the dimensional and performance requirements for this connection style, making it appropriate for systems where standardized face-seal hose ends are specified.

Installation Notes

This fitting is installed by qualified hydraulic technicians during hose assembly or field repair of hydraulic lines. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Use proper hose assembly tooling to ensure correct insertion depth and swage or crimp specifications are met per the hose manufacturer guidelines. Inspect the face seal surface for nicks or contamination before assembly, as Seal-Lok connections rely on the face seal for leak-free performance.
