Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong lubricant, which can degrade Buna-N.Always consult compatibility charts for appropriate lubricants.
Over-stretching or twisting the O-ring during installation.Handle the O-ring gently and ensure it sits squarely in the groove without distortion.

Common Applications

  • Hydraulic systems
  • Pneumatic systems
  • Fluid power equipment

⚠️ Engineering Warnings

  • Not suitable for applications involving ketones, esters, or strong oxidizing agents.
  • Operating temperature range: -40°F to +257°F (-40°C to +125°C). Exceeding this range can compromise seal integrity.
