ANSI/ASME A13.1 Pipe Marking Reference

Brady pipe markers are designed to comply with ANSI/ASME A13.1, the standard for identification of piping systems. Key requirements include:

• Color coding by fluid class: Yellow/Black = Other liquids — including glycol supply and return lines, coolants, and other non-flammable, non-toxic liquid systems not covered by other color categories
• Size C marker (2 in H, 1.3 in character height) is required for pipes with 2.5–3.875 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. Brady Strap-On Pipe Marker Styles

The BradySnap-On (B-915 coiled plastic) wraps around the pipe and snaps into place using the coil tension — no tools, straps, or adhesive required. It is ideal for pipes in the 0.75–6 in OD range where the coil can grip the pipe securely. For larger pipes (6 in OD and above) or insulated pipes where the coil cannot grip, the Brady Strap-On style (secured with two nylon straps) is recommended. Both styles use B-915 plastic and are removable and reapplicable. The 4190-C is also available in Strap-On style for larger pipe sizes — contact MTE Solutions for the correct size and style for your application.

Frequently Asked Questions

What pipe diameter does the Brady 4190-C fit?
The 4190-C is a size C marker designed for pipes with an outside diameter of 2.5–3.875 inches. The same "Glycol Supply" legend is available in other sizes (A through H and Strap-On styles) to cover a full range of pipe ODs from 0.75 in up to 15 in. Contact MTE Solutions for the correct size for your pipe diameter.

Why is the Brady 4190-C black on yellow?
Per ANSI/ASME A13.1, black on yellow is the required color scheme for "Other Liquids" — a category that includes glycol-based fluids such as glycol supply and return lines used in HVAC, chilled water, and process cooling systems. The yellow background with black text provides high visibility and communicates the fluid class consistently across the facility.

How does the BradySnap-On marker install?
The BradySnap-On uses a coiled B-915 plastic construction that wraps around the pipe and snaps into place using the natural tension of the coil — no tools, straps, or adhesive required. It can be removed and reapplied in other locations. It is suitable for pipes in the 0.75–6 in OD range where the coil can grip the pipe surface securely.

Is the Brady 4190-C 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 glycol piping systems in HVAC and process cooling applications.

Does the Brady 4190-C meet ANSI/ASME A13.1 requirements?
Yes. Brady BradySnap-On pipe markers are designed to meet ANSI/ASME A13.1 requirements for pipe identification, including correct color coding, legend, character height, and marker size for the applicable pipe diameter range.
