Parker BD-1J543-8-6-1 Seal-lok Swivel 90 Elbow Fitting

Product Description

The PARKER BD-1J543-8-6-1 is a female Seal-Lok swivel 90-degree elbow fitting designed for hydraulic hose assemblies. It connects to hoses with a 3/8-inch (0.375 inches) inside diameter and uses a 1/2-inch threaded Seal-Lok interface to create a leak-resistant, face-seal connection. Constructed from steel, this fitting is built for the pressure demands of industrial and mobile hydraulic systems. The swivel design allows the hose to be positioned without twisting during assembly or service. Hydraulic technicians and fluid power specialists install this fitting when routing hoses through tight angles in equipment such as construction machinery, agricultural equipment, and industrial hydraulic circuits.

This fitting is suited for hydraulic hose assemblies where a 90-degree change in hose direction is required at the connection point. The Seal-Lok face-seal design reduces the risk of leakage compared to tapered-thread fittings, making it appropriate for both high-cycle and high-pressure applications. It is sized for hose size 6 (3/8-inch ID) and is commonly used by fluid power specialists assembling or repairing hydraulic lines in mobile and stationary equipment across industrial, agricultural, and construction sectors.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed down the hydraulic system fully before disconnecting or installing any fitting. The Seal-Lok face-seal design requires the mating port to have a clean, undamaged flat seating surface; inspect the port face before assembly. Follow the fitting manufacturer's recommended assembly procedure for Seal-Lok swivel fittings, and do not over-torque, as damage to the face seal surface will result in leakage.
