About Selecting Pipe Markers

Adhesive-Back Pipe Markers


Apply directly onto clean, dry pipes for clear identification of contents.
Style A have an alternating message. Wrap them around the pipe and you can read the contents whether the arrow points left or right.
Style B have a removable arrow; apply the message to a pipe and then turn the arrow to match your system’s flow direction. For a more secure hold, pair these with pipe marker tape—just layer the tape over the edge of your markers then wrap it around the full diameter of a pipe.
Pipe markers that meet ASME A13.1 adhere to requirements that, for a given pipe size, they have the proper minimum character height, identify contents with a message, indicate flow direction with an arrow, and designate hazardous classifications with a specific marker color. For messages with multiple marker color options, choose the color that best identifies the hazardous properties of the contents according to the ASME designations.

Snap-On Pipe Markers

Label greasy and oily pipes where adhesive won’t hold—these markers coil around your pipe. Use them to indicate your pipe’s contents and flow direction. Markers for pipe OD 6” or larger secure with the included nylon cable ties.
ASME A13.1 requires that, for a given pipe OD, markers have a minimum character height, identify contents with a message, indicate flow direction with an arrow, and designate hazard classifications with a specific marker color. For messages with multiple marker color options, choose the color that best identifies the hazardous properties of the contents according to the ASME designations.

Reflective Pipe Markers

Identify pipe contents in low-light conditions. Apply these adhesive-back markers directly onto clean, dry pipes. They have a removable arrow; apply the message to a pipe and then turn the arrow to match your system’s flow direction.
For a more secure hold, pair these with pipe marker tape—just wrap the tape around the end of the pipe marker and the full diameter of the pipe.
ASME A13.1 requires that, for a given pipe OD, markers have a minimum character height, identify contents with a message, indicate flow direction with an arrow, and designate hazard classifications with a specific marker color. For messages with multiple marker color options, choose the color that best identifies the hazardous properties of the contents according to the ASME designations.

Weather-Resistant Inspection Record Tags
Tags are laminated in plastic or aluminum so they hold up outdoors.
Plastic-laminated tags resist moisture and are almost impossible to tear. Write on them using a pencil, pen, or permanent marker. Attach them using the included cable tie.
