Featuring a flat, countersunk head, this plug sits flush with the pipe or fitting surface, providing a smooth, low-profile finish that prevents obstruction in high-traffic areas. Its lead-free construction ensures compliance with potable water and plumbing safety standards, making it ideal for residential, commercial, and industrial plumbing applications. Facilitates both routine maintenance and emergency servicing of plumbing systems.
