Part Number: 6400L

37° JIC Male x SAE ORB Male Adapter Long

Product Overview

The Delphi Fittings Part 6400L is a specialized straight adapter designed for connecting JIC (Joint Industry Council) 37° flare systems to SAE O-Ring Boss (ORB) ports, particularly where extended reach is necessary. This fitting features a male JIC 37° flare on one end and a male SAE O-Ring Boss thread with an extended length on the other. The extended ORB end is specifically designed to engage with recessed or hard-to-reach ORB ports often found in compact hydraulic component arrangements. Like the standard 6400 adapter, it is used to connect a hydraulic hose with a female JIC swivel nut or a flared tube to components like pumps, valves, or manifolds, ensuring a secure, leak-free transition. It is manufactured from durable carbon steel and zinc-plated for corrosion resistance.

Applications

The Part 6400L adapter is particularly useful for:

Connecting hydraulic lines to ORB ports that are recessed within component housings or located in areas with limited wrench clearance.
Situations where standard length adapters cannot adequately reach or seat the O-ring in the ORB port.
Mobile equipment hydraulics where components are often tightly packaged.
Industrial machinery with deep-set ports or manifold blocks.
Ensuring proper O-ring compression and seal integrity in challenging installation scenarios.

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, confirm the O-ring is correctly sized for the fitting, lubricated with system-compatible fluid, and properly seated in its groove.
Carefully guide the extended male ORB end into the recessed female ORB port, ensuring it threads smoothly 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.
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.
Use backup wrenches where appropriate to prevent distortion of lines or components during tightening.
