Installation Procedure

1. Ensure the mating groove surfaces are clean, free from debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the component, avoiding overstretching or nicking with sharp edges. 3. Gently seat the O-ring into its designated groove, ensuring it is uniformly positioned and not twisted.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to cuts or nicks in the O-ring.Apply lubricant and gently guide the O-ring into the groove, using appropriate tools if necessary to avoid direct contact with sharp edges.
Installing a twisted O-ring, which compromises the seal and can lead to premature failure.Visually inspect the O-ring before and during installation to ensure it is seated flat and uniformly within the groove without any twists.
