Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage or permanent deformation.Apply lubricant to both the O-ring and the groove. Gently stretch and ease the O-ring into place, using a smooth, rolling motion if necessary.
Installing a twisted or pinched O-ring, which compromises seal integrity and leads to premature failure.Visually inspect the O-ring before and during installation to confirm it is seated evenly and without twists or pinching.

Common Applications

  • Aerospace fluid systems
  • Automotive fuel and hydraulic lines
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Ensure compatibility of O-ring material with all media and operating temperatures.
  • Avoid exposing Buna-N to strong ozone or UV radiation, which can degrade the material.
