Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners that compress the O-ring beyond its elastic limit.Tighten fasteners to the manufacturer's specified torque to prevent premature failure and extrusion.
Using incompatible lubricants or cleaning agents that degrade the Buna-N material.Consult the O-ring material compatibility chart and use only approved lubricants and cleaning agents.

Common Applications

  • Hydraulic systems requiring oil and fuel resistance
  • Chemical processing equipment with moderate temperature and pressure
  • Aerospace components demanding high strength and corrosion resistance

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding Buna-N's recommended operating range.
  • Avoid exposure to ozone, ketones, esters, and chlorinated hydrocarbons, which can degrade Buna-N.
