Eaton 04Z-102-BG Hydraulic Hose Male Pipe Rigid Fitting

Product Description

The EATON 04Z-102-BG is a male pipe rigid fitting designed for use with hydraulic hose assemblies in fluid power systems. Built from steel with a straight shape and NPTF threaded connection, this fitting provides a pressure-rated, leak-resistant seal at the hose-to-system interface. It carries a 1/8-27 thread size, an inside diameter of 0.25 inches, and an outside diameter of 0.125 inches. At 1.84 inches in overall length and weighing 0.1 pounds, it is a compact, single-piece rigid connector suited for tight routing applications. It meets SAE J1176 standards and belongs to the Eaton Z Series fitting line, making it a traceable, spec-grade component for professional hydraulic technicians.

This fitting is intended for use in hydraulic hose assemblies where a male pipe rigid end connection is required. It is commonly installed in mobile equipment, industrial machinery, and fluid power circuits that require NPTF threaded fittings at hose termination points. Eaton specifies this part for use with several hose series, including EC110, EC115, EC118, EC210, EC215, H0105, H0106, H104, H115, H116, H145, H145R, H1571, H1776, H1777, H1812, H190, H190H, and H1981, among others, within the noted size ranges listed in Eaton compatibility documentation.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power systems and SAE fitting standards. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. NPTF threads rely on thread-form interference for sealing — inspect threads for damage before assembly and follow SAE J1176 assembly guidance for proper engagement. Do not over-tighten, as this can damage the dry-seal thread form and compromise the fitting.
