Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, leading to O-ring extrusion or damage.Adhere to recommended torque specifications for all mating hardware.
Using incorrect O-ring size for the groove, resulting in poor sealing or rapid failure.Verify O-ring dimensions (ID, OD, cross-section) against groove specifications before installation.
Installing the O-ring with twists or kinks, compromising its sealing ability.Ensure the O-ring is laid flat and evenly seated within the groove without any distortions.
