Parker 10343-6-4 Male Rigid Hydraulic Hose Fitting

Product Description

The PARKER 10343-6-4 is a male rigid straight fitting designed for hydraulic hose assemblies. It connects a size 4 hose with a 0.25 inch inside diameter to a mating port using a 9/16-18 threaded Male JIC 37 degree flare interface. The fitting is made from steel and measures 1.84 inches in overall length. It is intended for use in hydraulic plumbing applications and is typically installed by hydraulic technicians, maintenance mechanics, and industrial service professionals working on fluid power systems.

This fitting is suited for straight-run hose terminations in hydraulic systems where a JIC 37 degree flare connection is specified. The 9/16-18 thread size is a common standard in mobile equipment, industrial machinery, and fluid power circuits. It is part of Parker Series 43 and is compatible with a broad range of Parker hose products. Typical install scenarios include fabricating or replacing hydraulic hose assemblies on presses, lifts, construction equipment, and similar systems.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic familiar with fluid power system assembly. Always depressurize and bleed the hydraulic system before disconnecting or installing any fittings. Use the correct 11/16 inch hex wrench to avoid rounding the fitting body. Torque to the fitting and hose manufacturer specifications for the thread size and connection type; do not overtighten a JIC flare fitting as this can damage the sealing surface.
