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

The FS2403-16-16 ORFS Union is a straight hydraulic adapter designed to connect two identical 1" (1 7/16-12) Male O-Ring Face Seal (ORFS) (-16) ports. Its precision-machined straight-body design ensures a secure, leak-free connection while maintaining smooth hydraulic flow and system reliability.

Manufactured from high-strength steel and built to comply with SAE 520101 / SAE J1453 standards, this union is engineered for heavy-duty hydraulic systems where durability, vibration resistance, and high-pressure performance are essential.

The ORFS (O-Ring Face Seal) system uses a flat sealing face with an elastomer O-ring, delivering excellent leak protection even under pressure spikes, vibration, and demanding operating conditions commonly found in industrial and mobile hydraulics.
