Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening or forcing the O-ring into the groove, leading to cuts or tears.Lubricate the O-ring and groove with a compatible lubricant and install gently, allowing the material to flex naturally.
Using an incompatible lubricant that degrades the Buna-N material.Always consult a chemical compatibility chart or the manufacturer's recommendations for appropriate lubricants.
Installing the O-ring in a dirty or damaged groove, compromising the seal.Thoroughly inspect and clean the groove for any nicks, burrs, or foreign particles before installation.

Common Applications

  • Hydraulic cylinder seals
  • Pneumatic actuator seals
  • General fluid containment in machinery

⚠️ Engineering Warnings
