Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the assembly, which can compress the O-ring beyond its elastic limit and lead to premature failure.Tighten the assembly to the manufacturer's recommended torque specifications, ensuring a secure but not overly compressed seal.
Using a sharp object to install the O-ring, which can nick or cut the sealing surface.Utilize appropriate O-ring installation tools or ensure hands are clean and free of sharp edges.

Common Applications

  • Hydraulic systems
  • Pneumatic assemblies
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Ensure material compatibility with the specific fluid or gas being sealed.
  • Avoid exposure to ozone, sunlight, or weathering, which can degrade Buna-N.
