- Color coding by fluid class: Green/White = Potable water, cooling water, cold water, and soft water systems
- Size D marker (1.3 in character height) is required for pipes with 4–6 in outside diameter per ANSI/ASME A13.1 sizing requirements

BradySnap-On vs. Other Brady Pipe Marker Styles
The BradySnap-On (B-915 plastic) is a non-adhesive coiled marker that snaps around the pipe for 360° visibility and is easily removable and reapplicable. It fits pipes 0.75–6 in OD and offers 5–8 years outdoor durability. It can be applied to dirty, oily, greasy, or rough surfaces where adhesive markers would not adhere. For larger pipes (6–15 in OD), Brady Strap-On markers are recommended. For permanent adhesive applications, Brady self-sticking vinyl markers are available.
Frequently Asked Questions
What pipe diameter does the Brady 4125-D fit?
The 4125-D is a size D marker designed for pipes with an outside diameter of 4–6 inches. The same "Soft Water" legend is available in other sizes (A through H) to cover pipe ODs from under 0.75 in up to 10 in and larger. Contact MTE Solutions for the correct size for your pipe diameter.
Why is the Brady 4125-D white on green?
Per ANSI/ASME A13.1, green with white text is the required color scheme for pipes carrying potable water, cooling water, cold water, and soft water. The green background immediately communicates the water service class of the pipe to facility personnel.

The BradySnap-On marker is a coiled plastic marker that installs tool-free by snapping around the pipe. No adhesive, strapping, or tools are required. It provides 360° visibility and can be repositioned or removed without leaving residue, making it ideal for pipes where adhesive markers are not practical or where periodic repositioning is needed.
