Caustic Pipe Marker

Pipe Labels: Caustic Pipe Marker

The pipe’s contents can be easily identified by using the Caustic Pipe Marker. The background of this marker is purple, and each side of it has a purple chevron arrow pointing outward. Additionally, the word “CAUSTIC” is centrally displayed in white. These pipe labels and markers have been created for tradespeople who are in charge of responding to maintenance requests and emergencies. The pipe marker’s purple colour indicates that acid is moving inside the pipe.

These directional Caustic Pipe Markers are supplied with flow direction arrows so installers can trim and apply the marker to match the direction of pipe flow on-site.

Supplied as a sticker: long-term digital print laminated for long-term use. With a life of 5 years or more. We use a Hi Tac vinyl which allows it to be applied to most surfaces.
