• Install the O-Ring — Gently place the selected o-ring into its designated groove or seating area. Use the included precision pick and hook tools if necessary for delicate placement or to maneuver the o-ring into tight spaces without pinching or stretching it.
• Reassemble and Test — Reassemble the component (e.g., faucet handle, pressure washer nozzle, engine part) ensuring all parts are correctly aligned. Once reassembled, test the functionality and check for any leaks to confirm the new o-ring has created a proper seal.
