Eaton 12Z-512-BG Jic 37 Male Rigid Straight Fitting

Product Description

The EATON 12Z-512-BG is a JIC 37 male rigid straight fitting designed for hydraulic hose assemblies. Manufactured from steel, it features a 1-1/16-12 threaded connection and a 0.75 inch hose inside diameter with a matching 0.75 inch outside diameter. The fitting measures 2.94 inches in overall length and accepts a 1-1/8 inch hex for installation. It is built to SAE J1176 standards and belongs to the Eaton Z series, making it a direct-fit option for a range of hydraulic hose assemblies used in industrial and mobile hydraulic systems. Licensed hydraulic technicians and fluid power specialists are the primary installers of this component.

This fitting is suited for use in hydraulic systems requiring a secure, leak-resistant JIC 37-degree flare connection. The straight body geometry makes it appropriate for inline hose termination applications where a rigid, non-swivel connection is preferred. It is commonly installed in industrial machinery and mobile equipment hydraulic circuits where the hose assembly must terminate at a fixed-angle port. The hose size designation is 12 mm, and the thread size is 1-1/16-12.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize the hydraulic system completely and relieve all stored pressure before removing or installing any fittings. Use a properly sized open-end or combination wrench on the 1-1/8 inch hex to tighten the fitting; avoid pipe wrenches that can deform the body. Follow SAE J1176 assembly guidelines for JIC flare fittings to ensure a proper metal-to-metal seat and leak-free joint.
