Installation Procedure

1. Ensure the mating groove is clean, free of debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the smaller diameter of the component, avoiding sharp edges or excessive force. 3. Gently seat the O-ring into the groove, ensuring it is flush and evenly distributed without twisting or pinching.
