Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation, leading to premature failure.Apply lubricant compatible with Buna-N and gently ease the O-ring into place, using appropriate tools if necessary to avoid excessive elongation.
Using an O-ring in an environment with incompatible fluids or extreme temperatures.Consult a chemical resistance chart and temperature range guide to confirm Buna-N suitability for the specific application before selecting the O-ring.

Common Applications

  • Hydraulic Systems
  • Automotive Fuel Systems
  • Pneumatic Cylinders
  • Fluid Power Seals
  • Industrial Machinery

⚠️ Engineering Warnings

  • Do not use in ozone, UV, or weathering environments as Buna-N degrades under these conditions.
  • Avoid exposure to ketones, esters, and aromatic hydrocarbons which can cause swelling and degradation.
