1. Installation Precautions


  1. Check the O-ring surface before installation, no cracks, burrs, deformation or aging damage.
  2. Keep the groove and installation position clean, no iron filings, dust or sharp edges.
  3. Use lubricant (silicone oil or glycerin) for installation; do not use sharp tools to pry the O-ring to avoid cutting.
  4. Do not overstretch the O-ring excessively, avoid twisting and folding during installation.
  5. Install in a low-temperature environment properly; avoid forced assembly under high temperature.
  6. Ensure the shaft and groove size match the O-ring specification, avoid too loose or too tight fit.
