• Identify the Correct Size — Carefully remove the old O-ring or measure the groove it fits into. Use calipers to determine the inner diameter (ID), outer diameter (OD), and cross-section (thickness) of the required O-ring. Compare these measurements to the 30 SAE AS568 inch sizes in the ZDBB kit.
• Prepare the Groove and O-Ring — Ensure the groove is clean and free of debris. Lightly lubricate the new O-ring with a compatible lubricant (e.g., silicone grease for high-temp applications) to aid installation and prevent damage during fitting.
• Install the O-Ring — Gently stretch and place the lubricated O-ring into the designated groove, ensuring it sits flat and is not twisted. Avoid using sharp tools that could nick or cut the O-ring, which would compromise its sealing ability.
• Test for Seal Integrity — Once installed, reassemble the component. Apply slight pressure or the intended operating force (e.g., turn on the faucet, start the engine) and check for any leaks. If leaks persist, try a slightly different size from the kit or re-examine the groove for damage.
