Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an O-ring that is too small or too large for the groove.Verify O-ring dimensions (ID, OD, CS) against groove specifications to ensure proper compression and sealing.
Twisting the O-ring during installation.Gently roll or place the O-ring into the groove to prevent twisting, which can lead to premature failure and leakage.

Common Applications
