Part Number: FS6403-SS

SAE ORFS Male x 37° Male JIC Adapter (Stainless Steel)

Product Overview

The Delphi Fittings Part FS6403-SS is a straight union adapter that connects a female O-Ring Face Seal (ORFS) swivel fitting to a female 37° JIC swivel fitting or flared tube. This adapter acts as a bridge between two different female-ended connections. Forged from high-grade 316 stainless steel, it provides a simple, reliable, one-piece solution for joining ORFS and JIC lines in corrosive, high-purity, or other demanding hydraulic systems.

Applications

The FS6403-SS adapter is a versatile connector for mixed-system plumbing:

Joining an ORFS hose assembly directly to a JIC hose assembly to extend a hydraulic line.
Transitioning from an ORFS-based system to JIC-based system components (or vice versa) in a straight run.
A vital component for repairs or modifications in corrosive environments where both ORFS and JIC female connections need to be joined.
Useful for creating inline test points between two different types of hose assemblies.

Installation & Usage Guidelines

ORFS End: Ensure the O-ring on the adapter's flat face is clean and lubricated. Connect the female ORFS swivel and tighten to its specified torque.
JIC End: Inspect the 37° flare cone on the adapter for any damage. Connect the female JIC swivel nut and tighten using the appropriate torque or FFWR method.
Use a wrench on the central hex of the adapter to hold it stationary while tightening the swivel nuts on either side, preventing transfer of torque.
