Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong lubricant, which can degrade the Buna-N material.Always use lubricants specified as compatible with Buna-N rubber, such as silicone or petroleum jelly.
Twisting or pinching the O-ring during installation.Ensure a smooth installation by rolling the O-ring into the groove; avoid forcing it.
Installing O-rings into contaminated or damaged grooves.Thoroughly clean and inspect the groove before installation; repair or replace if damaged.

Common Applications

  • Hydraulic cylinders and pumps
  • Fuel and oil handling equipment
  • Automotive power steering systems
  • Pneumatic actuators

⚠️ Engineering Warnings

  • Not recommended for use with ozone, strong acids, or ketones.
  • Continuous exposure to elevated temperatures above 250°F (121°C) can degrade material properties.
