FS0318-12 SAE O-Ring Face Seal ORFS Nut

FS0318-12 ORFS Nut | Steel O-Ring Face Seal Hydraulic Nut

The FS0318-12 SAE O-Ring Face Seal (ORFS) Nut is a precision-engineered hydraulic fitting component designed to provide a secure, leak-resistant connection in ORFS hydraulic systems. Manufactured from high-strength carbon steel and finished with trivalent zinc plating, it offers excellent corrosion resistance and long-term durability in demanding operating environments.

Built in compliance with SAE 520110 standards, this ORFS nut is designed for high-pressure hydraulic applications where reliability, vibration resistance, and consistent sealing performance are critical. The ORFS system combines straight threads with an elastomer O-ring to deliver superior leak protection under pressure fluctuations and harsh conditions.
