FS0318-08 SAE O-Ring Face Seal ORFS Nut

FS0318-08 ORFS Braze Nut | Steel O-Ring Face Seal Hydraulic Nut

The FS0318-08 SAE O-Ring Face Seal (ORFS) Braze Nut is a high-strength hydraulic fitting component designed for secure, leak-resistant ORFS connections. Manufactured from durable carbon steel and finished with trivalent zinc plating, it provides excellent corrosion resistance and long-lasting performance in demanding hydraulic systems.

Engineered to meet SAE 520110 standards, this ORFS nut is designed to work with O-Ring Face Seal systems that use straight threads combined with an elastomer O-ring, ensuring a tight, vibration-resistant seal even under high pressure and fluctuating load conditions.

Its braze-style design makes it suitable for applications where permanent or semi-permanent assembly is required, commonly used in hydraulic tube and fitting fabrication.
