Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage or deformation.Apply even, moderate pressure during installation, ensuring the O-ring seats smoothly into its groove.
Installing a dry O-ring, causing increased friction and potential tearing.Always lubricate the O-ring with a manufacturer-recommended lubricant compatible with the fluid and O-ring material.
Using an incompatible lubricant that degrades the Buna-N material.Consult the O-ring and system specifications to select a lubricant that is chemically compatible with both Buna-N and the application's operating fluids.

Common Applications

  • Hydraulic systems
  • Pneumatic cylinders
  • Chemical processing equipment
  • Aerospace fluid control

⚠️ Engineering Warnings

  • Verify chemical compatibility with the specific operating fluid and temperature range.
  • Avoid exposure to ozone, strong acids, and polar solvents, which can degrade Buna-N.
