Installation & Handling Tips

🔧 Installation Best Practices

  • Clean groove thoroughly before installation
  • Lubricate with compatible lubricant
  • Avoid sharp edges during installation
  • Check for proper compression (typically 15-25%)
  • Verify groove dimensions match AS568 standards

📦 Storage & Handling

  • Store in cool, dark, dry environment
  • Avoid exposure to UV light and ozone
  • Keep away from sharp objects
  • Rotate stock using FIFO method
  • Shelf life:

Common Issues & Solutions

O-Ring Troubleshooting Guide
Problem Possible Cause Solution Prevention
Premature hardening Excessive temperature or ozone Replace with higher temp material Check operating temperature limits
Swelling Chemical incompatibility Switch to chemically resistant material Review chemical compatibility chart
Extrusion damage Excessive pressure or clearance Use harder durometer or backup ring Design proper groove clearances
Surface cracking Ozone, UV, or flexing Use ozone-resistant material Protect from environmental exposure
