Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a sharp object to install the O-ring, causing nicks or tears.Utilize a rounded, non-marring installation tool or a bit of lubricant to ease the O-ring into its groove.
Installing a twisted or spiraled O-ring, leading to immediate leakage.Verify the O-ring is seated flat and uniformly within the groove before assembly.

Common Applications
