Parker 10656-8-8 Female Jic 37 Hydraulic Fitting 5000 Psi

Product Description

The PARKER 10656-8-8 is a female JIC 37-degree, 45-degree dual flare swivel straight hydraulic hose fitting designed for high-pressure hydraulic systems. Machined from steel, this Series 56 fitting connects an -8 hose (1/2 inch inside diameter) to a 3/4-16 JIC threaded port using a straight body profile. With a 5,000 psi pressure rating, it is built for demanding fluid power applications. The swivel design allows rotation during installation, reducing hose twist and simplifying routing in tight plumbing configurations. The overall length is 2.54 inches with a 1-inch body diameter and a 13/16-inch hex for standard wrench engagement. Licensed hydraulic technicians and fluid power specialists are the primary installers.

This fitting is suited for mobile equipment, industrial hydraulic circuits, and stationary power units where JIC 37-degree flare connections are specified. It is compatible with Parker hose series 510C, 518C, 540N, 548N, 560, 590, and D6R. Typical applications include construction equipment, agricultural machinery, and industrial press lines that require reliable, leak-resistant swivel connections at high operating pressures.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed the hydraulic system fully before disconnecting or installing any fittings. Use a calibrated torque wrench and follow the fitting manufacturer's torque specifications for 3/4-16 JIC connections. Inspect the flare seat and swivel nut for damage before assembly, and avoid over-tightening, which can distort the flare sealing surface.
