Pipe markers offer a quick way to identify the contents of a pipe, especially in emergencies. In Australia, pipe identification is standardized by AS 1345-1995. A pipe marker indicates both the contents of the pipe and the direction of flow. Simply cut off the unnecessary arrow and apply the marker to the pipe.
