Eaton 12E-112 Male Pipe Rigid Hydraulic Hose Fitting

Product Description

The EATON 12E-112 is a male pipe rigid hydraulic hose fitting designed for high-pressure fluid transfer applications in industrial and mobile hydraulic systems. Built from steel with a straight configuration, this fitting features an NPTF threaded connection at 3/4-14 thread size, providing a pressure-tight seal without additional sealant tape when properly installed. It accommodates hoses with a 0.75 inch inside diameter and 0.75 inch outside diameter, rated for a maximum working pressure of 5000 psi. Licensed plumbers, hydraulic system technicians, and fluid power specialists are the typical installers of this fitting in both OEM and service environments.

This fitting is suited for use in industrial hydraulic assemblies, mobile equipment hydraulic lines, and high-pressure fluid conveyance systems where a rigid, leak-free male pipe connection is required. It belongs to EATON Series E and is compatible with specific hose series commonly found in demanding hydraulic circuit applications. The straight shape simplifies routing in tight or linear plumbing layouts where angled or swivel fittings are not needed.

Key Features

• NPTF threaded connection at 3/4-14 thread size for pressure-tight sealing
• Maximum working pressure of 5000 psi for demanding hydraulic circuits
• Steel construction for durability in high-pressure and high-cycle environments
• Straight shape supports direct, in-line hose-to-port connections
• 1-1/16 inch hex size for standard wrench installation
• Hose size 12 designation for consistent system specification

Compatibility

Compatible with EATON hose series H009, H209, H243, H265, H275, H277, H285, H435, and H436 as specified by the manufacturer. Verify hose inside diameter and thread engagement before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist familiar with NPTF thread standards. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. NPTF threads are designed to seal on the thread form itself, but inspect threads for damage before assembly and apply appropriate thread sealant only if required by system specifications. Use a calibrated torque wrench sized for the 1-1/16 inch hex to avoid over-tightening, which can crack the fitting or distort the port.
