Eaton 12Z-108-BG Hydraulic Hose Male Pipe Rigid Fitting

Product Description

The EATON 12Z-108-BG is a male pipe rigid fitting designed for hydraulic hose assemblies. It connects hose ends to threaded ports in hydraulic circuits using a straight MPT (male pipe tapered) thread configuration. Made from steel, this fitting is built for the pressure and vibration demands of industrial and mobile hydraulic systems. The thread size is 1/2-14, the hose inside diameter is 0.75 inches, and the overall installed length is 2.78 inches. It is installed by hydraulic system technicians and fluid power specialists working on equipment maintenance or hose assembly fabrication.

This fitting is suited for straight-run hose terminations in hydraulic systems where a rigid male pipe connection is required. It belongs to the EATON Z Series and is compatible with a range of EATON hose part numbers across EC and H series lines. Typical applications include mobile equipment, industrial machinery, and fluid power circuits requiring a reliable threaded end connection. The hex size of 1-1/8 inches allows for standard wrench installation without special tooling.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed down the hydraulic system completely before removing or installing any fittings. Use the 1-1/8 inch hex and a calibrated torque wrench to seat the tapered pipe thread properly — follow EATON assembly guidelines and applicable industry standards for MPT thread engagement. Avoid cross-threading and do not overtighten, as tapered pipe threads are susceptible to fitting damage with excessive torque.
