The FS2403-04-04 ORFS Union is a straight hydraulic adapter designed to connect two 9/16-18 Male O-Ring Face Seal (ORFS) (-04) connections. Its straight union design provides a secure, leak-free connection between ORFS hydraulic components while maintaining full flow efficiency.

Manufactured from high-strength steel and built to SAE 520101 compliance standards, this fitting is engineered for demanding hydraulic applications where reliable sealing and high-pressure performance are essential. The ORFS sealing system utilizes an O-ring at the face of the fitting to create a superior leak-resistant connection, making it ideal for systems subject to vibration, pressure spikes, and harsh operating conditions.
