- Color coding by fluid class: Yellow/Black = Flammable, Combustible, or Oxidizing fluids (including fuel oil)
- Size D marker (2.8125 in H, 1.3 in character height) is required for pipes with 4–6 in outside diameter per ANSI/ASME A13.1 sizing requirements
- Marker placement: Adjacent to all valves and flanges, at both sides of floor/wall penetrations, adjacent to changes in direction, and every 25–50 ft on straight runs
BradySnap-On vs. Other Brady Pipe Marker Styles
Brady offers multiple pipe marker mounting styles. The BradySnap-On (B-915) is a non-adhesive coiled vinyl marker that snaps around the pipe for 360° visibility and is easily removable. It is rated for pipes 0.75–6 in OD and offers 5–8 years outdoor durability. For larger pipes (6–15 in OD), Brady Strap-On markers are recommended. For permanent adhesive applications, Brady self-sticking markers (B-946 vinyl) are available.
Frequently Asked Questions
What pipe diameter does the Brady 4066-D fit?
The 4066-D is a size D marker designed for pipes with an outside diameter of 4–6 inches. For other pipe sizes, Brady offers the same legend in 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 4066-D black on yellow?
Per ANSI/ASME A13.1, black on yellow is the required color scheme for pipes carrying flammable, combustible, or oxidizing fluids — including fuel oil. The yellow background with black text provides high visibility and immediately communicates the hazard class of the pipe contents to facility personnel.
How does the BradySnap-On marker install?
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.
Is the Brady 4066-D suitable for outdoor use?
Yes. The B-915 plastic construction provides 5–8 years average outdoor durability with a service temperature range of -40°F to 140°F. It is abrasion-resistant and chemical-resistant, suitable for exposed outdoor pipe marking applications.
Does the Brady 4066-D meet ANSI/ASME A13.1 requirements?
Yes. Brady BradySnap-On pipe markers are designed to meet ANSI/ASME A13.1-2023 requirements for pipe identification, including correct color coding, legend, character height, and marker size for the applicable pipe diameter range.
