Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, leading to O-ring extrusion.Torque fasteners to manufacturer specifications to prevent over-compression.
Using sharp or abrasive tools during installation, nicking the O-ring.Employ only smooth, rounded installation tools or the O-ring's own flexibility.
Incorrect groove dimension, causing improper sealing or premature failure.Verify that the gland dimensions meet the O-ring's specifications precisely.
