Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, which can compress the O-ring excessively and lead to premature failure.Adhere to specified torque values for all fasteners to prevent over-compression of the sealing element.
Using incompatible lubricants or cleaning agents that can degrade the Buna-N material.Consult the material compatibility chart and use only approved lubricants and cleaning solutions for Buna-N and Aluminum 6061.

Common Applications

  • Hydraulic systems
  • Pneumatic actuators
  • Fuel delivery systems
  • Automotive components
  • Industrial machinery

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding Buna-N's operational limits.
