Join ORFS Tubing With a Straight-Through Connection
The FS2403 ORFS Union is made for applications where two ORFS tube assemblies need to be connected directly. Its straight-through configuration keeps the hydraulic line running in the same direction without adding an unnecessary change in routing.
The available size combinations include equal unions as well as reducing unions, making FS2403 useful for a variety of hydraulic tube configurations.
ORFS Face Seal for Reliable Hydraulic Connections
ORFS fittings use an elastomeric O-ring positioned at the fitting face to create the primary seal. The FS2403 union works with the corresponding ORFS components to bring the sealing faces together and create a dependable hydraulic connection.
This sealing design is particularly useful in hydraulic equipment where vibration, pressure, and mechanical movement can place additional demands on fitting connections.
Steel Construction for Heavy-Duty Hydraulic Use
FS2403 ORFS Unions are manufactured with steel bodies, providing the strength required for industrial and mobile hydraulic applications. A clear zinc trivalent finish provides additional surface protection for demanding operating environments.
The combination of steel construction and ORFS sealing makes FS2403 a practical choice for high-pressure hydraulic tube assemblies.

Built for High-Pressure Applications
FS2403 ORFS Unions are rated for working pressures up to 6,000 PSI, with the actual pressure capability depending on fitting size, tube size, and complete assembly conditions.
They are suitable for systems exposed to:
- High hydraulic pressure
- Continuous mechanical shock
- Vibration
- Dynamic loads
- Heavy-duty operating conditions
For extreme-pressure applications, verify the pressure rating of the complete assembled system and all mating components.
Buna-N or Viton O-Ring Options
The standard FS2403 configuration uses a Buna-N O-ring with 90 Durometer hardness. Viton O-rings are available upon request for applications requiring additional temperature resistance.
The standard operating temperature range listed for the fitting is -30°F to 275°F.
