FS0318-16 SAE O-Ring Face Seal ORFS Nut

FS0318-16 ORFS Nut | Steel O-Ring Face Seal Hydraulic Nut

The FS0318-16 SAE O-Ring Face Seal (ORFS) Nut is a high-performance hydraulic fitting component designed to ensure secure and leak-resistant ORFS connections in demanding hydraulic systems. Manufactured from durable carbon steel and finished with trivalent zinc plating, it offers excellent corrosion resistance and long service life in industrial environments.

Built to comply with SAE 520110 standards, this ORFS nut is engineered for high-pressure hydraulic applications where vibration resistance, sealing integrity, and system reliability are critical. The ORFS design uses straight threads combined with an elastomer O-ring to create a strong, leak-free seal even under pressure spikes and heavy-duty operating conditions.
