Parker 1JS43-8-8 Female Seal-lok Swivel Fitting 0.5 in

Product Description

The PARKER 1JS43-8-8 is a female Seal-Lok swivel fitting designed for hydraulic hose assemblies requiring a secure, leak-resistant threaded connection. Built from steel and configured in a straight shape, this Series 43 fitting accepts a 1/2-inch hose inside diameter and uses a 1/2-inch thread size for attachment. At 2.65 inches overall length, it is a compact, purpose-built component for high-pressure hydraulic circuits. Licensed hydraulic technicians and industrial maintenance professionals install this fitting when assembling or repairing hydraulic lines in mobile or stationary equipment.

This fitting is rated for use across a wide range of Parker hydraulic hose series in both residential and commercial or industrial applications. It is suited for straight-run hose terminations where a swivel end is needed to prevent hose twist during assembly or service. The Seal-Lok interface provides a face-seal connection that reduces the risk of leakage compared to tapered thread designs, making it a preferred choice in high-cycle or high-vibration hydraulic systems.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with Parker Seal-Lok assembly procedures. Always depressurize and bleed down the hydraulic system before removing or installing fittings. Use appropriate hydraulic fitting tools and torque wrenches; refer to Parker assembly specification documentation for torque values applicable to this fitting series. Inspect the face-seal surface and O-ring seating area for damage before assembly to ensure a leak-free connection.
