FS4000-08-V Viton® 75 Durometer Face Seal O-Ring

Product Description

The FS4000-08-V Viton® 75 Durometer Face Seal O-Ring is a high-temperature hydraulic face seal O-ring specifically designed for SAE O-Ring Face Seal (ORFS) hydraulic fittings. This Viton ORFS face seal O-ring is used in hydraulic systems where heat, oil exposure, and pressure cycling can cause standard hydraulic O-rings to fail.

• High-temperature and chemical-exposed hydraulic circuits
  

Manufactured from Viton® fluoroelastomer, this hydraulic face seal O-ring offers excellent resistance to high temperatures, petroleum-based hydraulic oils, fuels, and harsh chemicals. The 75 durometer Viton O-ring hardness provides the correct balance between flexibility and extrusion resistance, ensuring consistent sealing in high-pressure ORFS hydraulic connections.

In ORFS hydraulic fittings, the O-ring creates a seal between two flat metal faces rather than relying on threads. Using a Viton ORFS hydraulic O-ring like the FS4000-08 improves leak prevention, especially in compact hydraulic systems exposed to vibration and thermal expansion.

This FS4000-08 Viton face seal O-ring is designed for Nominal Size 08 ORFS hydraulic fittings, which are commonly used in compact hydraulic hose assemblies, precision fluid power equipment, and industrial machinery where space is limited but sealing reliability is critical.
