Important advices for a damage-free O-ring assembly

When it comes to fitting your seals, caution is called for. Because every bit of damage to an O-ring means additional costs. Damage during installation should therefore definitely be avoided. There are a few important things to bear in mind.

Here are the most important:

  • Use assembly grease or oils (ensure you check the elastomer’s resistance)
  • When fitting, use a fitting chamfer of 15–20° (lead-in chamfer) (see fig.)
  • No O-ring torsion due to rolling
  • No sharp-edged crossovers, processing marks, threads or bores in the area in and around where the O-ring will be fitted
  • No dirt or residues in the fitting groove or on the O-ring
