Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening or excessive force during installation, leading to nicks or cuts on the O-ring.Apply gentle, even pressure during installation. Use appropriate installation tools if necessary to avoid direct contact with sharp edges.
Using incompatible lubricants or cleaning agents that degrade the Buna-N material.Always refer to chemical compatibility charts and use only approved lubricants and cleaning solutions specifically designed for Buna-N and the application environment.

Common Applications

  • Hydraulic Systems
  • Pneumatic Systems
  • Chemical Processing Equipment
  • Aerospace Components

⚠️ Engineering Warnings

  • Ensure the O-ring material (Buna-N) is compatible with all media and operating temperatures in the intended application.
  • Avoid exposing the O-ring to ozone, UV light, or strong oxidizing agents, as these can degrade the Buna-N compound.
