Installation Procedure

1. Ensure the mating groove is clean, free of debris, and properly dimensioned according to the O-ring's specifications. 2. Lightly lubricate the O-ring and groove with a compatible lubricant (e.g., silicone grease) to facilitate installation and prevent damage. 3. Carefully install the O-ring into the groove, avoiding any stretching or twisting, ensuring it sits flush and without any pinching.
