Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation.Gently roll or slide the O-ring into the groove. Avoid excessive pulling or stretching which can lead to premature failure.
Using incompatible lubricants.Always verify that the lubricant is compatible with Nylon and the service media to prevent swelling or degradation of the O-ring.
Installing on a damaged or dirty groove.Thoroughly clean and inspect the groove for sharp edges, burrs, or contaminants that could damage the O-ring during installation or operation.

Common Applications

  • Hydraulic and pneumatic systems
  • Automotive components
  • Industrial machinery sealing

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications.
  • Avoid prolonged exposure to strong acids and bases.
