Using your K-Tuned AN Male Weld Bung is easy. First, pick the right size for your custom application, whether it's a catch can, radiator, or oil system. Clean the area where you'll be welding to ensure a strong bond. Then, carefully weld the bung into place. When it comes to maintenance, keep an eye on the welds for any signs of wear or damage. If you notice any issues, it's best to replace the bung. Store the bung in a dry place to prevent corrosion. Also, make sure to use the appropriate welding equipment and follow safety guidelines during the installation process.
