FS2403-24-20 ORFS Union

FS2403-24-20 ORFS Union | Steel Straight Hydraulic Adapter

The FS2403-24-20 ORFS Union is a heavy-duty straight hydraulic fitting designed to connect a 1 1/2" (2-12) Male O-Ring Face Seal (ORFS) (-24) port to a 1 1/4" (1 11/16-12) Male ORFS (-20) port. Its precision-machined straight union body ensures a secure, leak-free inline connection while maintaining consistent hydraulic flow and system efficiency.

Manufactured from high-strength steel and compliant with SAE 520101 / SAE J1453 standards, this adapter is engineered 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 surface with an elastomer O-ring, providing superior leak protection even under pressure spikes, pulsation, and demanding industrial or mobile hydraulic conditions.
