Eaton 12Z-516-BG Jic 37 Male Rigid Hydraulic Hose Fitting

Product Description

The EATON 12Z-516-BG is a JIC 37-degree male rigid hose fitting designed for use in hydraulic fluid power systems. Built from steel, this fitting connects a size 12 hydraulic hose to a 1-5/16-12 threaded port using the standard 37-degree flare seat geometry. The rigid straight configuration holds the hose end in a fixed position, making it suited for installations where hose routing does not require an angled adapter. Licensed hydraulic technicians and industrial maintenance professionals typically install this fitting when assembling or repairing high-pressure hydraulic lines on mobile or stationary equipment.

This fitting is appropriate for hydraulic hose assemblies that terminate at a JIC 37-degree male thread port. The size 12 hose designation corresponds to a 1-5/16-inch hose inside diameter. With a 1-3/8-inch hex, the fitting accepts standard combination wrenches or open-end wrenches available in most hydraulic service kits. It is commonly used in agricultural machinery, construction equipment, and industrial hydraulic circuits where reliable JIC threaded connections are specified.

Key Features

• JIC 37-degree male rigid fitting for straight, fixed-position hose termination
• Designed for size 12 hydraulic hose with 1-5/16-12 thread specification
• Steel construction for durability in high-pressure hydraulic service
• 1-3/8-inch hex size for wrench access during assembly and torque application
• Single-piece rigid body with no swivel — maintains hose orientation after assembly

Compatibility

Designed as an OEM-style replacement fitting for size 12 hydraulic hose assemblies using JIC 37-degree male rigid end connections with a 1-5/16-12 thread size.

Installation Notes

Installation should be performed by a qualified hydraulic technician following applicable industry standards for hydraulic fittings and hose assemblies. Relieve all system pressure and depressurize the hydraulic circuit completely before removing or installing any fittings. Inspect the JIC 37-degree flare seat on both the fitting and mating port for nicks or contamination before assembly. Do not over-tighten; follow the fitting manufacturer torque specifications appropriate to the thread size and material.
