Installation Procedure

1. Ensure the mating groove surfaces are clean, dry, and free from debris or burrs. 2. Carefully install the O-ring into the groove, avoiding any stretching or twisting if possible. 3. Apply a light coat of compatible lubricant to the O-ring and groove for easier assembly and to prevent damage during mating, if recommended for the specific application.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Stretching or twisting the O-ring during installation.Gently roll or place the O-ring into the groove to maintain its original shape and ensure a proper seal.
Using an incompatible lubricant or no lubricant at all.Always consult the application's material compatibility chart for the correct lubricant. Lubrication aids installation and protects the O-ring.
Installing on a dirty or damaged groove surface.Thoroughly clean and inspect the groove for any damage before O-ring installation to prevent premature seal failure.

Common Applications

  • Fluid power systems (hydraulic and pneumatic)
  • Chemical processing equipment
  • Food and beverage machinery

⚠️ Engineering Warnings

  • Ensure compatibility with the specific fluid or gas being sealed.
  • Avoid exposure to high concentrations of certain solvents or steam, which can degrade silicone.
