Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, leading to extrusion or excessive compression of the O-ring.Adhere to specified torque values for all fasteners to ensure proper sealing pressure without over-compression.
Using a dry O-ring in a dynamic application, causing friction and premature wear.Lubricate the O-ring with a compatible lubricant before installation in dynamic applications.

Common Applications

  • Hydraulic cylinder sealing
  • Pneumatic actuator seals
  • Fuel and oil system components

⚠️ Engineering Warnings
