Installation Procedure

1. Ensure the mating groove is clean, free of debris, and meets specified dimensional tolerances. 2. Carefully lubricate the O-ring and groove with a compatible lubricant to prevent damage during installation. 3. Gently stretch and place the O-ring into the groove, avoiding any sharp tools or excessive force that could nick or cut the seal.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong lubricant, which can degrade the silicone or the mating materials.Always consult compatibility charts and use lubricants specifically rated for silicone and the service environment.
Forcing the O-ring into a tight groove without proper lubrication, leading to nicks or cuts.Employ a suitable lubricant and ensure the O-ring is correctly sized for the groove to allow for controlled installation.

Common Applications

  • Chemical Processing Equipment
  • Pharmaceutical Manufacturing
  • Food and Beverage Production
  • High-Temperature Seals
