Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, causing excessive compression and premature failure.Tighten fasteners incrementally to the specified torque value, ensuring even pressure distribution across the O-ring.
Using incompatible lubricants that degrade the Buna-N material.Consult material compatibility charts and use only lubricants specifically approved for Buna-N.

Common Applications

  • Hydraulic systems
  • Pneumatic assemblies
  • Automotive seals

⚠️ Engineering Warnings

  • Not recommended for use with strong oxidizing agents, ketones, or esters.
  • Avoid prolonged exposure to ozone or UV radiation, which can degrade Buna-N.
