Tips

Always check the O-ring material compatibility with the fluid in your system. NBR is excellent for mineral oils and fuels but not recommended for brake fluids or strong acids. Store the case in a cool, dry place away from direct sunlight to prolong shelf life. When installing, lightly lubricate the O-ring with compatible grease to prevent twisting and ensure a proper seal.
