Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Twisting the O-ring during installation.Ensure the O-ring is placed straight into the groove and avoid rotating it as components are assembled.
Using incompatible lubricants or cleaning agents.Consult material compatibility charts to ensure lubricants and cleaning agents will not degrade the Buna-N or Titanium.

Common Applications

  • Aerospace Fluid Connectors
  • Chemical Processing Equipment
  • High-Pressure Hydraulic Systems

⚠️ Engineering Warnings

  • Ensure operating temperatures remain within the specified range for Buna-N to prevent premature degradation.
  • Avoid exposure to strong oxidizing agents, ketones, esters, and chlorinated hydrocarbons, which can degrade Buna-N.
