Part Number: FS6400L-SS

SAE ORFS Male x SAE ORB Male Straight Adapter Long (Stainless Steel)

Product Overview

The Delphi Fittings Part FS6400L-SS is an extended-length straight adapter designed to connect a female O-Ring Face Seal (ORFS) swivel to a female SAE O-Ring Boss (ORB) port where extra reach is required. As a long-body version of the standard FS6400-SS, this fitting is perfect for accessing deeply recessed ports or clearing obstructions. Manufactured from 316-grade stainless steel, it provides a reliable, leak-proof connection with maximum corrosion resistance for challenging hydraulic applications.

Applications

The extended reach of the FS6400L-SS makes it a crucial problem-solver in specific situations:

Accessing deeply recessed ORB ports on hydraulic pumps, motors, and manifolds that are difficult to reach with standard fittings.
Providing necessary clearance to route a hose assembly around a nearby obstacle without kinking or stressing the hose.
Simplifying connections in complex plumbing arrangements by extending the connection point to a more accessible area.
Ideal for use in corrosive environments like marine and chemical processing where reliable connections must be made in challenging locations.

Installation & Usage Guidelines

ORB End: Inspect and lubricate the O-ring. Thread the fitting into the recessed ORB port and tighten to the recommended torque.
ORFS End: With the adapter now securely installed, connect the female ORFS swivel nut. Ensure the O-ring on the adapter's face is clean and lubricated.
Use a wrench on the adapter's hex body to hold it stationary while tightening the ORFS swivel nut to its specified torque.
