Meter seals, part of multipurpose seals group, are used with electric meters, gas meters, and water meters and are usually molded in polycarbonate. Designed for only a single use, they are destroyed when removed. Some meter security seals contain components which glow under ultraviolet light, allowing the security seal to be easily located in darkness.
