Opti-Code™ Self-Adhesive Pipe Markers

Our Most Popular and Cost-Effective Pipe Markers

Opti-Code™ Self-Adhesive Pipe Markers are a perfect way to quickly communicate pipe contents. Best when used on clean, dry pipes - simply peel off the back liner and stick it to the pipe for either indoor or outdoor use. All these markers meet the ANSI/ASME A13.1 2015 standard when used with Arrows-On-A-Roll™ tape or Pipe Marker Directional Arrows to indicate flow direction. Available in various sizes, colors and fully customizable for any application or need.
