Parker 10356-6-6 Male Jic Straight Hose Fitting 3/8 in 5000 Psi

Product Description

The PARKER 10356-6-6 is a male JIC rigid straight hydraulic hose fitting designed for high-pressure hydraulic lines in industrial and mobile equipment applications. Machined from steel, this straight fitting accepts a 3/8-inch (hose size 6) hydraulic hose with a 0.375-inch inside diameter and uses a 9/16-18 JIC threaded connection. It carries a pressure rating of 5,000 psi, making it suitable for demanding hydraulic circuits. At 2.15 inches in overall length and 0.11 pounds, it is a compact, direct-replacement component installed by hydraulic technicians and equipment mechanics during hose assembly or field repair work.

This fitting is used in hydraulic hose assemblies on industrial machinery, mobile equipment, and fluid power systems requiring a reliable straight-end JIC connection. Parker specifies this fitting for use with the following hose series: 510C, 518C, 540N, 548N, 560, 590, and D6R. It is a Series 56 fitting suited for applications where a permanent, rigid straight end connection is required at the hose-to-port interface.

Key Features

• 3/8-inch hose inside diameter (hose size 6) compatibility
• Steel construction for durability in hydraulic fluid environments
• Straight rigid design with 5/8-inch hex for standard wrench assembly
• Compact overall length of 2.15 inches for tight routing applications

Compatibility

Designed for use with Parker hose series 510C, 518C, 540N, 548N, 560, 590, and D6R in 3/8-inch (hose size 6) configurations.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic. Depressurize and fully isolate the hydraulic circuit before removing or installing any fittings. JIC fittings rely on a 37-degree flare metal-to-metal seat — inspect the flare and fitting seat for nicks or debris before assembly. Use a backup wrench on the hose stem while torquing the nut to avoid twisting the hose assembly.
