FS2403-16-12 ORFS Union

FS2403-16-12 ORFS Union | Steel Straight Hydraulic Adapter

The FS2403-16-12 ORFS Union is a high-performance straight hydraulic fitting designed to connect a 1" (1 7/16-12) Male O-Ring Face Seal (-16) port to a 3/4" (1 3/16-12) Male O-Ring Face Seal (-12) port. Its precision-machined straight union design ensures a secure, leak-free connection while maintaining optimal hydraulic flow and system integrity.

Manufactured from high-strength steel and engineered to comply with SAE 520101 / SAE J1453 standards, this adapter is built for heavy-duty hydraulic applications where reliability, pressure resistance, and long service life are essential.

The ORFS (O-Ring Face Seal) system uses a flat-face sealing surface with an elastomer O-ring, delivering excellent resistance against leaks, vibration, and pressure spikes commonly found in demanding hydraulic environments.
