Secure the ORFS Connection With the Right Nut
The FS0318 ORFS Nut is an essential component in an ORFS tube assembly. It works with the corresponding sleeve and ORFS body to hold the tubing securely and bring the sealing faces together.
For hydraulic systems where vibration and pressure can put stress on connections, using the correct ORFS nut and matching components is important for maintaining a dependable assembly.
Designed Around the ORFS Sealing System
ORFS fittings use a flat face with an elastomeric O-ring to create the primary seal. The FS0318 nut helps bring the tubing, sleeve, and fitting body together so the sealing surfaces can properly engage.
This design makes ORFS connections well suited to applications where minimizing leakage and maintaining connection integrity are important.
Built for High-Pressure Hydraulic Service
FS0318 ORFS nuts are designed for demanding fluid-power applications with working pressures up to 6,000 PSI, depending on tube size, fitting size, and the complete assembly.
They are suitable for systems operating under:
- High hydraulic pressure
- Continuous mechanical shock
- Vibration and dynamic loads
- Industrial operating conditions
- Mobile equipment movement
Always verify the pressure capability of the complete hydraulic assembly rather than relying on the nut rating alone.

FAQs
What is an FS0318 ORFS Nut?
FS0318 is an SAE O-Ring Face Seal (ORFS) nut used with compatible ORFS sleeves and fitting bodies in hydraulic tube assemblies.
What does ORFS mean?
ORFS stands for O-Ring Face Seal. The connection uses an elastomeric O-ring positioned at the fitting face to provide the primary seal.
What pressure can FS0318 ORFS Nuts handle?
The listed working pressure is up to 6,000 PSI, depending on tube size, fitting size, and overall assembly conditions.
What components work with an FS0318 nut?
The FS0318 nut is designed to work with compatible ORFS sleeves, tubing, and fitting bodies.
What sizes are available?
The current FS0318 range includes -04, -06, -08, -10, -12, -16, -20, and -24 sizes.
Are FS0318 nuts suitable for mobile hydraulic equipment?
Yes. They are intended for demanding hydraulic applications, including mobile and construction equipment and systems exposed to vibration and continuous mechanical shock.
Is the O-ring included with the FS0318 nut?
The collection page identifies FS0318 as an ORFS nut and lists its compatible ORFS components, but it does not state that an O-ring is included with the nut. Confirm the exact product configuration before ordering.
