Installation Procedure

1. Ensure the mating groove surfaces are clean, dry, and free of debris or burrs. 2. Lightly lubricate the O-ring with a compatible lubricant (e.g., silicone grease) if recommended for the specific application. 3. Carefully install the O-ring into the groove, avoiding any stretching or twisting, ensuring it sits flush within the groove.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring deformation or damage.Handle the O-ring gently. If resistance is met, verify the groove dimensions and O-ring compatibility. Consider using a suitable lubricant.
Incorrect O-ring size selection, resulting in either leakage or over-compression.Always verify the required groove dimensions and O-ring specifications against the O-ring's internal and external diameters and cross-section.

Common Applications
