Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this Viton O-ring boasts an inside diameter of 8.253 inches, an outside diameter of 4.550 inches, and a cross-section of 0.184 inches. The fluoroelastomer (FKM) material, commonly known as Viton, provides exceptional resistance to a broad spectrum of chemicals, fuels, oils, and high temperatures up to 400°F (204°C). The integrated brass component enhances its structural integrity and provides electrical conductivity where required. This combination makes it ideal for demanding static and dynamic sealing applications in aerospace, automotive, chemical processing, and oil & gas industries.
