Eaton 12Z-P12-BG Hydraulic Hose Fitting Male Straight Orb

Product Description

The EATON 12Z-P12-BG is a male straight thread O-ring boss (ORB) hydraulic hose fitting machined from steel. It connects a 12 mm hose to a port with a 1-1/16-12 thread and seals through a face O-ring seated against the port boss, eliminating the need for thread sealant. The 1-1/4-inch hex allows for standard wrench engagement during torquing. This fitting is used in mobile and industrial hydraulic systems where a leak-free, straight-thread connection is required. Installation is typically performed by hydraulic system technicians and fluid power specialists.

This fitting is suited for hydraulic hose assemblies in mobile equipment, agricultural machinery, construction equipment, and industrial power units where ORB port connections are standard. The straight-thread O-ring design is common in systems requiring reliable sealing under high-pressure cycling. It is compatible with hose ends and port bosses conforming to the 1-1/16-12 straight thread ORB standard.

Key Features

• Male straight thread O-ring boss (ORB) design seals at the port face, not the threads
• 12 mm hose size with 1-1/16-12 thread for direct port engagement
• Steel construction for durability in high-pressure hydraulic service
• 1-1/4-inch hex size for wrench access during assembly
• Single-piece construction — no additional adapters required for standard ORB ports

Compatibility

Designed as an OEM-style replacement fitting for hydraulic hose assemblies using 12 mm hose ends and 1-1/16-12 straight thread ORB port connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed down the hydraulic system fully before removing or installing any fittings. Inspect the O-ring for damage before assembly and lubricate it lightly with clean hydraulic fluid prior to installation. Follow the equipment manufacturer and applicable fluid power standards for proper assembly torque and re-torque procedures.
