FS4000-20-V Viton® 75 Durometer Face Seal O-Ring

Product Description

The FS4000-20-V Viton® 75 Durometer Face Seal O-Ring is designed for Nominal Size 20 SAE ORFS hydraulic fittings, delivering dependable sealing performance in systems exposed to high temperatures, aggressive fluids, and continuous pressure cycles. Viton® ensures long-term elasticity and resistance to thermal degradation, even in harsh operating environments.

Specifications

• Material: Viton® Fluoroelastomer
  
• Hardness: 75 Durometer
  
• Nominal Size: 20
  

Applications

• High-temperature ORFS hydraulic connections
  
• Industrial hydraulic manifolds
  
• Chemical-exposed hydraulic systems
  

This O-ring is optimized for flat face sealing surfaces, reducing leak paths and preventing extrusion under pressure. The 75-durometer hardness allows controlled compression while maintaining flexibility, making it suitable for both static and dynamic hydraulic sealing applications.
