In order to promote greater safety in factories and plants, ANSI developed the A13.1-1981 standard, entitled ≥Scheme For The Identification of Piping Systems≤. This standard reduces the chances for error and confusion when working in or around pipes and ducts by identifying contents.

Our 6-mil vinyl pressure-sensitive pipe and electrical markers are an inexpensive way to mark pipes and conduits. A clear laminate protects against harsh plant conditions. Available in rolls 1" x 18 yards (SP-Series) and 2" x 18 yards (PM-Series), 72 markers per roll, perforated every 9 inches. Also available in a 6-1/2" x 30' marker with no perforation.



Color coding unmarked pipes reduces injuries, especially when outside assistance is needed in emergency situations.


Pressure-sensitive vinyl directional arrows are used to indicate flow direction of pipe contents. Colors are OSHA/ANSI approved for pipe and conduit marking. They can be applied alone or in combination with our pipe markers.
