Part Number: 6400

37° JIC Male x SAE ORB Male Adapter

Product Overview

The Delphi Fittings Part 6400 is a straight adapter designed for high-pressure hydraulic systems, facilitating a reliable connection between a JIC (Joint Industry Council) 37° flare connection and an SAE O-Ring Boss (ORB) port. This fitting features a male JIC 37° flare on one end and a male SAE O-Ring Boss thread on the other. It is typically used to connect a hydraulic hose with a female JIC swivel nut or a flared tube to a component with an SAE ORB port, such as a pump, valve, cylinder, or manifold. Manufactured from durable carbon steel and zinc-plated for corrosion resistance, the Part 6400 adapter ensures a secure, leak-free transition between these two common hydraulic connection types.

Commonly Available Sizes (Part #6400 Series)

Delphi Fittings offers the 37° JIC Male x SAE ORB Male Adapter in a wide range of common JIC and ORB size combinations. Sizes are typically denoted by dash numbers (e.g., -04 for 1/4", -06 for 3/8") or corresponding thread specifications.

Examples include (Male JIC x Male ORB):

6400-04-04: 1/4" (7/16-20) JIC Male x -04 (7/16-20) ORB Male
6400-06-06: 3/8" (9/16-18) JIC Male x -06 (9/16-18) ORB Male
6400-08-08: 1/2" (3/4-16) JIC Male x -08 (3/4-16) ORB Male
6400-10-10: 5/8" (7/8-14) JIC Male x -10 (7/8-14) ORB Male
6400-12-12: 3/4" (1-1/16-12) JIC Male x -12 (1-1/16-12) ORB Male
6400-16-16: 1" (1-5/16-12) JIC Male x -16 (1-5/16-12) ORB Male
Reducing configurations also available, e.g., 6400-06-04: 3/8" JIC Male x -04 ORB Male

Note: JIC and ORB threads can share the same UNF thread size for a given dash size, but the sealing mechanisms are different. Always ensure compatibility. For unlisted size combinations, please contact our sales team.

Applications

The Part 6400 adapter is essential for integrating JIC and ORB components within hydraulic systems:

Connecting hydraulic hoses with female JIC swivel ends to pumps, valves, cylinders, or manifolds with SAE ORB ports.
Adapting rigid flared tubing with JIC connections to ORB ports.
Mobile equipment hydraulics (construction, agriculture, forestry).
Industrial machinery and hydraulic power units.
Applications where high-pressure, leak-free connections are critical between these two common fitting types.

Installation & Usage Guidelines

Ensure all threads and sealing surfaces (JIC flare, ORB O-ring groove, mating JIC seat, and ORB port boss) are clean, undamaged, and free of contaminants.
For the ORB end, ensure the O-ring is correctly sized, lubricated with system-compatible fluid, and properly seated in its groove on the male ORB fitting.
Thread the male ORB end into the female ORB port by hand until the O-ring makes contact and the fitting shoulder is snug. Then, tighten with a wrench to the recommended torque specification for the ORB size. This compresses the O-ring to create the seal.
Connect the male JIC end to the female JIC swivel nut. Ensure the 37° flare surfaces align correctly. Tighten the JIC nut to the recommended torque. The JIC connection seals on the metal-to-metal flare.
Use backup wrenches where appropriate to prevent distortion of lines or components.
