Part Number: 6407

SAE ORB Male x SAE ORB Male Union

Product Overview

The Delphi Fittings Part 6407 is an SAE ORB Male x SAE ORB Male Union, designed as a straight connector for joining two female SAE O-Ring Boss (ORB) ports of the same size. This fitting features male SAE O-Ring Boss threads on both ends, each equipped with an O-ring for a superior seal. It is essential for creating a direct, in-line connection between components such as valves, manifolds, or pump ports that both feature female ORB connections. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 6407 union ensures a robust, high-pressure, and leak-free link within hydraulic systems.

Applications

The Part 6407 SAE ORB Male Union is essential for creating straight connections between two female ORB ports:

Joining two hydraulic components (e.g., valve to manifold, pump to filter base) that both have female ORB ports.
Extending a line where both connection points are female ORB.
Use in mobile equipment, industrial machinery, and hydraulic power units where ORB connections are standard.
Applications demanding high-pressure, leak-free in-line connections.

Installation & Usage Guidelines

Ensure all threads and sealing surfaces (O-ring grooves on the union, mating female ORB port bosses) are clean, undamaged, and free of contaminants.
Confirm that the O-rings are correctly sized for each male ORB end of the union, lubricated with system-compatible fluid, and properly seated in their grooves.
Thread one male ORB end of the union into a female ORB port by hand until the O-ring makes contact and the fitting shoulder is snug.
Thread the other male ORB end of the union into the second female ORB port by hand.
Use a wrench on the hex body of the union to tighten both connections to the recommended torque specification for the ORB size. Tighten evenly to ensure proper O-ring compression on both ends.
Use backup wrenches on mating components if necessary to prevent them from turning during tightening.
