Part Number: 6410

SAE ORB Male x SAE ORB Female Reducer/Expander

Product Overview

The Delphi Fittings Part 6410 is an SAE ORB Male x SAE ORB Female Reducer/Expander adapter. This versatile straight fitting is designed to connect two SAE O-Ring Boss (ORB) components of different thread sizes. It features a male SAE ORB thread on one end and a female SAE ORB port (with internal boss for O-ring sealing) on the other. Depending on the specific configuration, this adapter can function as a reducer (e.g., larger male ORB to smaller female ORB) or an expander (e.g., smaller male ORB to larger female ORB). Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 6410 provides a reliable, leak-proof solution for adapting ORB port sizes in hydraulic systems.

Key Features & Specifications

Material	High-Grade Carbon Steel
End 1 Configuration	Male SAE O-Ring Boss (ORB) (per SAE J1926-1 / ISO 11926-1)
End 2 Configuration	Female SAE O-Ring Boss (ORB) (per SAE J1926-1 / ISO 11926-1)
Function	Reducer or Expander (connects different ORB thread sizes)
Body Style	Straight Adapter with Hex Body for wrench tightening.
Sealing Mechanism	Male ORB End: O-ring (supplied with this end) seals against the boss in the mating female ORB port. Female ORB End: Seals via the O-ring on the mating Male ORB fitting against the internal boss of this adapter's female ORB port.
Corrosion Protection	Standard Zinc Plating for enhanced durability.
Primary Function	To adapt between different sizes of male and female SAE O-Ring Boss connections.
Working Pressure	Suitable for high-pressure hydraulic applications. Specific ratings vary by size.
O-Ring Material	Typically Buna-N (Nitrile) 90 Durometer. Viton® or other materials available upon request.

Note: This list shows examples of common reducing/expanding combinations. Many other size configurations are possible. Always specify the Male ORB size and Female ORB size required. For unlisted size combinations, please contact our sales team.

Applications

The Part 6410 adapter is essential for connecting ORB components of different sizes:

Stepping up or stepping down port sizes within a hydraulic manifold or on components like pumps, valves, and cylinders.
Integrating existing components with mismatched ORB port sizes into a new or modified system.
Use in mobile equipment, industrial machinery, and any hydraulic system utilizing SAE O-Ring Boss connections where size adaptation is necessary.
Providing flexibility in system design and component selection.

Installation & Usage Guidelines

Ensure all threads and sealing surfaces (O-ring grooves, mating port bosses, internal boss of the female ORB end) are clean, undamaged, and free of contaminants.
For the male ORB end of this adapter, ensure its O-ring is correctly sized, lubricated, and seated. Thread this end into the mating female ORB port and tighten to the recommended torque.
For the female ORB end of this adapter, ensure the mating male ORB fitting has its O-ring correctly sized, lubricated, and seated. Thread the male ORB fitting into this adapter's female ORB port and tighten to the recommended torque.
Use appropriate wrenches on the hex body of the adapter and on the mating fittings. Use backup wrenches as needed to prevent distortion.
Proper torque is crucial for achieving the correct O-ring compression and a reliable seal on both ORB connections.
