Parker 10656-4-4 Female Jic Swivel Straight Fitting 6000 Psi

Product Description

The PARKER 10656-4-4 is a female JIC 37-degree, 45-degree dual flare swivel straight hydraulic hose fitting designed for high-pressure fluid power applications. Machined from steel with a threaded connection type, it accepts a 1/4-inch (4 hose size) hydraulic hose and is rated to 6,000 psi working pressure. The straight body measures 2.05 inches in overall length with a 9/16-inch hex and a 7/16-20 thread size. Licensed HVAC technicians, hydraulic system mechanics, and industrial maintenance professionals install this fitting when building or repairing hydraulic hose assemblies that require a reliable JIC swivel connection at the hose end.

This fitting is suited for use in mobile hydraulic systems, industrial fluid power circuits, and equipment requiring a low-profile straight swivel end. The swivel design allows the hose to be positioned without twisting during installation, reducing assembly stress. It is part of the Parker Series 56 fitting line and is listed under California Proposition 65 standards. Its compact steel construction makes it appropriate for tight-routing applications where both pressure integrity and joint articulation are critical.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with JIC fitting assemblies. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Use a backup wrench on the fitting body when tightening to avoid twisting the hose or damaging adjacent components. Verify thread engagement and seating of the JIC 37-degree flare before returning the system to operating pressure.
