Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong O-ring size for the groove.Always verify the O-ring's dimensions against the groove specifications to ensure a proper interference fit and effective seal.
Installing a dry O-ring, leading to tearing or stretching.Apply a thin layer of compatible lubricant to the O-ring before installation to ease insertion and protect the material.
Twisting or rolling the O-ring during installation.Gently roll or slide the O-ring into the groove, ensuring it lies flat and unkinked for optimal sealing performance.
