Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, which can over-compress and damage the O-ring.Tighten fasteners to the manufacturer's recommended torque specifications only.
Installing the O-ring with a twist, which compromises its sealing ability and leads to premature failure.Ensure the O-ring is laid into the groove without any twisting; a lubricant can aid in proper seating.

Common Applications

  • Hydraulic systems
  • Pneumatic equipment
  • Fluid power applications
  • Automotive seals

⚠️ Engineering Warnings
