    Made-to-Order Adhesive-Back Pipe Markers for Refrigerant Systems

    Image of System. Front orientation. Contains Annotated, MultipleImages. Pipe Markers. Made-to-Order Adhesive-Back Pipe Markers for Refrigerant Systems.
    Create custom labels to meet ANSI/IIAR 2 standards to identify refrigeration systems. These pipe markers have an adhesive back, so you can stick them directly to clean, dry pipes.
    For a more secure hold, pair these with pipe marker tape (not included). Wrap the tape over the edge of your markers then wrap it around the full diameter of the pipe.
    Chemical Markers—8 Characters
    Chemical markers describe the refrigerant in your pipe—either ammonia or CO2—and the system the refrigerant is supplying. To Order: Please specify your system’s abbreviation (up to 8 characters, including spaces), the refrigerant state, pressure, and flow direction. Single arrows come perforated, so you can turn them to match your system’s flow direction.
