Eaton 12Z-510-BG Jic 37 Male Rigid Hydraulic Hose Fitting

Product Description

The EATON 12Z-510-BG is a JIC 37-degree male rigid hydraulic hose fitting manufactured from steel. It connects a 7/8-inch hydraulic hose to a JIC 37-degree female seat using a 7/8-14 UNF straight thread. The rigid body style means the fitting does not swivel after assembly, making it suited for fixed-orientation plumbing where the hose line does not need to rotate at the connection point. Hydraulic technicians and fluid power mechanics install this type of fitting in mobile equipment, industrial machinery, and hydraulic power units where JIC flare connections are specified.

This fitting is used in hydraulic systems that require a leak-resistant JIC 37-degree flare interface. It is appropriate for fixed hydraulic plumbing runs in construction equipment, agricultural machinery, material handling equipment, and stationary industrial hydraulic circuits. The 7/8-inch hose size and 7/8-14 thread make it a common size in mid-range hydraulic circuits. Installation is performed by fluid power technicians or mechanics working on hydraulic assemblies that call out JIC 37-degree male straight fittings.

Key Features

• JIC 37-degree male rigid fitting for fixed-orientation hydraulic connections
• 7/8-14 UNF thread size for standard JIC female seat engagement
• Designed for 7/8-inch hydraulic hose (12 mm nominal hose size)
• 1-1/8-inch hex size for wrench installation and torquing
• Steel construction for durability in hydraulic fluid service

Compatibility

Designed as an OEM-style replacement rigid hose fitting for hydraulic systems using JIC 37-degree flare connections with 7/8-inch hose and 7/8-14 UNF thread ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize the hydraulic system completely and relieve any stored pressure before removing or installing fittings. Clean all mating surfaces and inspect the JIC 37-degree flare seat for nicks or damage before assembly. Tighten using a backup wrench on the port to prevent component damage; do not overtighten, as JIC fittings rely on metal-to-metal flare seat contact.
