Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, which can damage the O-ring.Apply gentle, even pressure and avoid pinching or stretching the O-ring excessively.
Installing the O-ring dry, leading to increased friction and potential wear.Always lubricate the O-ring with a compatible lubricant before installation.
Using an incompatible lubricant that can degrade the Buna-N material.Consult material compatibility charts to ensure the lubricant is suitable for Buna-N.

Common Applications

  • Hydraulic cylinder seals
  • Pneumatic actuator seals
  • Pump and valve seals

⚠️ Engineering Warnings

  • Ensure compatibility with the fluid medium and operating temperature range.
  • Inspect O-ring for damage before installation to guarantee seal integrity.
