Eaton 04Z-106-BG Hydraulic Hose Male Pipe Rigid Fitting

Product Description

The EATON 04Z-106-BG is a male pipe rigid fitting designed for hydraulic hose assemblies. It provides a fixed, non-swivel connection between a hydraulic hose and a threaded port, maintaining a leak-resistant seal under high-pressure hydraulic system conditions. The fitting is machined from steel and uses an NPTF thread form, which relies on thread interference to seal without requiring a separate sealant. With a 3/8-18 thread size and a 4 mm hose size, this fitting suits compact hydraulic circuits where a straight, rigid connection is specified. A 11/16 inch hex allows standard wrench installation. Licensed plumbers, hydraulic system technicians, and industrial maintenance mechanics typically install fittings of this type.

This fitting is suited for use in hydraulic hose assemblies on mobile equipment, industrial machinery, and fluid power systems requiring a rigid male pipe end connection. It is applicable where NPTF-threaded ports are used and a non-rotating, straight-line hose termination is required. The compact steel construction makes it appropriate for moderate to high-pressure hydraulic circuits in both stationary and mobile applications.

Key Features

• NPTF thread form provides a pressure-tight mechanical seal through thread interference
• Rigid (non-swivel) design maintains fixed hose orientation after assembly
• Steel construction for durability in hydraulic fluid environments
• 3/8-18 thread size compatible with standard NPTF female ports
• 11/16 inch hex for torque application with standard open-end or box wrenches
• Sold individually, one fitting per package

Compatibility

Designed as an OEM-style replacement rigid male pipe fitting for hydraulic hose assemblies using 4 mm hose with 3/8-18 NPTF threaded port connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with fluid power system service. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fitting. NPTF threads are designed to seal on thread engagement alone, but inspect threads for damage before assembly and apply thread sealant only if specified by the system manufacturer. Do not overtighten, as this can crack ports or distort the fitting body.
