Midland Industries 6410O2016 Reducer Expander Steel Adapter

Product Description

The MIDLAND INDUSTRIES 6410O2016 is a steel SAE O-Ring Boss reducer/expander adapter used in hydraulic plumbing systems to transition between a 1-1/4-inch Male O-Ring Boss (MORB) port and a 1-inch Female O-Ring Boss (FORB) port. It is rated for a maximum operating pressure of 1800 psi and a maximum operating temperature of 375 degrees F, making it suitable for demanding industrial and mobile hydraulic applications. The MORB connection carries a thread size of 1-5/8-12 and the FORB connection carries a thread size of 1-5/16-12. Hydraulic technicians and fluid power mechanics install this fitting when upsizing or downsizing port connections on cylinders, manifolds, pumps, or valves without modifying the host component.

This adapter is designed for hydraulic systems found in mobile equipment, industrial machinery, and fluid power circuits where SAE O-Ring Boss porting is the specified connection standard. The 6410 series MORB-to-FORB configuration allows a technician to connect lines of differing sizes at a single port location, eliminating the need for additional tees or custom fabrication. Its compact body dimensions make it a practical choice for installations where space around the port is limited. It is appropriate for use in both stationary and mobile hydraulic applications operating within rated pressure and temperature limits.

Key Features

• 1-1/4-inch Male O-Ring Boss inlet transitions to 1-inch Female O-Ring Boss outlet
• 1800 psi maximum operating pressure for demanding hydraulic service
• 375 degrees F maximum operating temperature
• MORB thread size 1-5/8-12 and FORB thread size 1-5/16-12 per SAE standard
• Steel construction for durability in industrial and mobile hydraulic environments
• Compact body at approximately 1.2 inches in length suits tight-clearance installations

Compatibility

Designed as an OEM-style SAE O-Ring Boss adapter for hydraulic systems utilizing standard MORB and FORB ported components such as pumps, motors, cylinders, manifolds, and valves with compatible SAE O-Ring Boss thread specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Before installing or removing any hydraulic fitting, fully depressurize and de-energize the hydraulic system and verify that stored pressure has been relieved. Inspect the O-Ring Boss seat and sealing surface for damage before assembly, and use a new, properly sized O-ring lubricated with system-compatible fluid. Follow applicable industry standards and equipment manufacturer specifications for port thread torque requirements.
