Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size O-ring for the groove.Always verify the O-ring's inside diameter, outside diameter, and cross-section against the groove dimensions to ensure a proper fit.
Damaging the O-ring during installation with sharp tools.Utilize appropriate plastic installation tools or lubricate the O-ring and groove to facilitate smooth insertion without causing tears or abrasions.
Installing an O-ring with a material incompatible with the fluid or environment.Confirm that the Buna-N material is suitable for the specific chemicals, temperatures, and pressures of the application. Consult material compatibility charts if necessary.

Common Applications

  • Hydraulic systems
  • Pneumatic cylinders
  • Fuel and oil handling equipment
