Parker 1JS43-16-16 Female Seal-lok Swivel Fitting 1 in

Product Description

The PARKER 1JS43-16-16 is a female Seal-Lok swivel fitting designed for high-pressure hydraulic hose assemblies. Built from steel with a straight, threaded configuration, this Series 43 fitting accepts a 1-inch inside diameter hose (Size 16) and delivers a secure, leak-resistant Seal-Lok connection. At 3.62 inches overall length, it is engineered for demanding fluid-power applications where a reliable swivel end is required at the hose termination. Licensed hydraulic technicians and industrial maintenance professionals are the primary installers of this component.

This fitting is used in mobile hydraulic systems, industrial fluid-power circuits, and heavy equipment plumbing where hose assemblies require a female Seal-Lok swivel interface. It is compatible with Parker hose series 187 TC, 187 ST, 302, 304, 387 TC, 387 ST, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487 TC, 487 ST, 722 TC, 722 ST, 787 TC, 787 ST, 797 TC, 797 ST, and 881 hoses. Typical installations are found in construction machinery, agricultural equipment, and industrial presses.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed down the hydraulic system completely before removing or installing any fittings. Use appropriate torque tooling for threaded hydraulic fittings and follow the fitting manufacturer's assembly instructions for Seal-Lok face-seal connections. Inspect the sealing face and O-ring seat for damage before assembly to ensure a leak-free joint.
