Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage or deformation.Apply gentle, consistent pressure and ensure proper lubrication to facilitate installation without undue stress on the O-ring.
Incorrectly sizing the O-ring for the groove, resulting in poor sealing or premature failure.Verify that the O-ring's dimensions (ID, OD, and cross-section) precisely match the groove specifications to achieve optimal compression and sealing.
