FS2403-20-20 ORFS Union | Steel Straight Hydraulic Adapter

The FS2403-20-20 ORFS Union is a heavy-duty straight hydraulic fitting designed to connect two identical 1 1/4" (1 11/16-12) Male O-Ring Face Seal (ORFS) (-20) ports. Its precision-machined straight union body ensures a secure, leak-free inline connection while maintaining smooth hydraulic flow and system efficiency.

Manufactured from high-strength steel and compliant with SAE 520101 / SAE J1453 standards, this adapter is built for high-pressure hydraulic systems where durability, vibration resistance, and long-term sealing reliability are critical.

The ORFS (O-Ring Face Seal) system uses a flat-face sealing design with an elastomer O-ring, delivering excellent leak prevention even under pressure spikes, pulsation, and harsh operating environments.
