Parker 1C543-28-16 Swivel Elbow Hydraulic Fitting 1 in 1000 Psi

Product Description

The PARKER 1C543-28-16 is a female Seal-Lok swivel short elbow hydraulic hose fitting designed for metric hydraulic systems requiring a reliable angled connection point. Constructed from steel, this fitting accepts a 1-inch hose diameter and is rated to 1,000 psi working pressure. The swivel design allows the hose to be oriented during installation without twisting the line, while the short elbow configuration provides a compact 90-degree transition where space is limited. The M36x2 metric thread ensures a secure, leak-resistant seal. This fitting is installed by hydraulic technicians and industrial mechanics on fluid power equipment, mobile machinery, and industrial hydraulic circuits.

This fitting is suited for metric hydraulic plumbing applications in both mobile and stationary equipment. The Seal-Lok face-seal thread form minimizes potential leak paths compared to tapered thread styles, making it a common choice in industrial and off-highway hydraulic assemblies. It is appropriate for use anywhere a short-radius elbow transition is needed at the hose-to-component junction. Technicians select this style when routing hoses away from obstructions in tight engine bays or hydraulic manifold installations.

Key Features

• Female Seal-Lok swivel connection reduces hose twist during assembly
• Short elbow body provides a compact 90-degree transition for tight routing
• 1,000 psi pressure rating suitable for medium-pressure hydraulic circuits
• M36x2 metric thread for compatibility with metric port connections
• Steel construction for durability in demanding hydraulic environments
• 1-inch hose diameter accommodates standard large-bore hydraulic hose

Compatibility

Designed as an OEM-style replacement or new-installation fitting for metric hydraulic hose assemblies using female Seal-Lok swivel end connections on 1-inch hose with M36x2 port threads.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and fully de-energize the hydraulic system before removing or installing any fittings. Inspect the face-seal O-ring seating surface for nicks or contamination before assembly; a damaged seating surface will prevent a proper seal. Torque the fitting to the hydraulic system manufacturer's specification for the thread size and do not over-tighten, as over-torquing can damage the face-seal seat.
