FS4000-06 Buna-N NBR Face Seal O-Ring | ORFS Hydraulic Seal

Product Description

The FS4000-06 Buna-N Face Seal O-Ring is engineered to provide dependable sealing performance in SAE O-Ring Face Seal (ORFS) hydraulic systems. Manufactured from 90-durometer Buna-N nitrile rubber, this O-ring delivers excellent resistance to hydraulic oils, mineral oils, and water-based fluids while maintaining elasticity under high pressure.

Specifications

• Material: Buna-N (Nitrile), 90 Durometer
  
• Shape: O-Ring
  
• Nominal Size: 06
  
• Compatible with SAE ORFS hydraulic fittings
  

Features

• High-pressure sealing performance
  
• 90-durometer hardness for extrusion resistance
  
• Oil and fluid compatible Buna-N material
  
• Designed for flat face ORFS connections
  

Applications

• ORFS hydraulic adapters
• High-pressure hose assemblies
  
• Industrial hydraulic systems
  

Designed for Nominal Size 06 ORFS fittings, this face seal O-ring compresses evenly between flat mating surfaces, minimizing the risk of leakage even under vibration or pressure fluctuations. It is suitable for extreme-pressure hydraulic systems operating up to 6000 PSI, depending on fitting configuration.
