Installation Procedure

1. Ensure the mating groove surfaces are clean, free of debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the smaller diameter of the mating component or into the groove, avoiding any sharp edges or tools that could nick or cut the material. 3. Gently seat the O-ring into the groove, ensuring it is uniformly compressed and not twisted or pinched during assembly.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring nicks or tears.Apply gentle pressure and use appropriate tools (if necessary) that are designed to avoid damaging the O-ring.
Incorrect O-ring size selection for the groove, resulting in improper compression or leakage.Verify the O-ring dimensions (ID, OD, CS) against the groove dimensions and design specifications before installation.
Installing on contaminated or damaged groove surfaces.Thoroughly clean and inspect the groove for any burrs, sharp edges, or debris that could compromise the seal.
