Detailed Engineering Specifications

Purpose-built for heavy-duty applications, this silicone O-ring boasts an inside diameter of 8.373 inches, an outside diameter of 5.057 inches, and a cross-section of 0.249 inches. Silicone's inherent flexibility and resilience provide excellent sealing capabilities across a broad temperature range, from -55°C to +200°C. Its inert nature makes it highly resistant to ozone, UV radiation, and many common chemicals, ensuring long-term performance in static and dynamic sealing applications. This material is particularly well-suited for use in systems employing brass components, as it minimizes the risk of galvanic corrosion and maintains seal integrity.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, leading to over-compression and premature O-ring failure.Adhere to specified torque values for all fasteners to ensure controlled compression.
Using O-rings made from incompatible materials that can degrade or react with the media or mating surfaces.Always verify material compatibility with the specific application environment and mating materials, particularly brass.

Common Applications

  • Hydraulic and pneumatic systems
  • Food and beverage processing equipment
  • Automotive and aerospace components

⚠️ Engineering Warnings

  • Avoid exposure to high concentrations of certain solvents or aggressive chemicals not specified for silicone compatibility.
  • Ensure O-ring is not subjected to excessive abrasion or mechanical damage during installation or operation.
