Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect O-ring size for the groove.Verify O-ring dimensions (ID, OD, CS) precisely match the groove specifications to ensure proper compression and sealing.
Overtightening fasteners, leading to O-ring extrusion.Follow recommended torque specifications for fasteners to prevent excessive compression and potential O-ring damage.
Using incompatible lubricants or cleaning agents.Always consult material compatibility charts to ensure lubricants and cleaning agents do not degrade the Buna-N material.

Common Applications

  • Hydraulic and pneumatic systems
  • Fuel and oil handling equipment
  • General industrial machinery sealing

⚠️ Engineering Warnings

  • Not recommended for use with ozone, strong acids, or polar solvents.
