Brady 4063-D FUEL OIL BradySnap-On Pipe Marker, Size D, 4–6" Pipe OD

Brady 4063-D FUEL OIL BradySnap-On Pipe Marker — Size D, 4–6" Pipe OD

The Brady 4063-D is a pre-printed FUEL OIL snap-on pipe marker designed for quick, tool-free installation on pipes with an outside diameter of 4 to 6 inches. Printed in bold Black on Yellow — the ANSI/ASME A13.1 color for Flammable/Combustible/Oxidizing fluids — this marker delivers instant, code-compliant pipe identification in industrial, commercial, and facility maintenance environments. Made from Brady B-915 coiled plastic, it snaps firmly onto the pipe and stays put, even on dirty, oily, greasy, or rough surfaces.

ANSI/ASME A13.1 Pipe Marking Reference

The Brady 4063-D uses Black on Yellow, the ANSI/ASME A13.1 color code for Flammable, Combustible, and Oxidizing fluid systems — including fuel oil lines. Proper pipe marking per ANSI/ASME A13.1 requires:

• Color coding by fluid class: Red = Firefighting | Orange = Toxic/Corrosive | Yellow = Flammable/Combustible/Oxidizing | Gray = Steam/Hot Water | Green = Potable/Cooling/Cold Water | Blue = Compressed Air
• Size selection by pipe OD: Size D (4063-D) fits 4–6" OD pipes. See 4063-A (¾–1⅜"), 4063-B (1½–2⅜"), 4063-C (2½–3⅞") for smaller diameters.
• Marker placement: At valves and flanges, at penetrations through walls/floors, at direction changes, and every 25–50 ft on straight runs.

Frequently Asked Questions

What pipe diameter does the Brady 4063-D fit?
The 4063-D (Size D) is designed for pipes with an outside diameter of 4 to 6 inches. For smaller pipes, Brady offers the same FUEL OIL legend in sizes A (¾–1⅜"), B (1½–2⅜"), and C (2½–3⅞").

Why is the 4063-D Black on Yellow?
Black on Yellow is the ANSI/ASME A13.1 color code for flammable, combustible, and oxidizing fluids — which includes fuel oil. This color combination ensures immediate visual identification and code compliance in facilities following the ANSI standard.

How does BradySnap-On installation work?
The marker is made from coiled B-915 plastic. You simply wrap it around the pipe and it snaps into place — no tools, adhesive, or hardware required. It can be applied even to dirty, oily, or rough pipe surfaces, making it ideal for both new construction and retrofits in older facilities.

Is the Brady 4063-D suitable for outdoor use?
Yes — the 4063-D is rated for outdoor use with 5 to 8 years of outdoor durability. It is abrasion-resistant and chemical-resistant, with a service temperature range of -40 °F to 140 °F.

Is the Brady 4063-D ANSI/ASME A13.1 compliant?
Yes. The 4063-D meets ASME (ANSI) A13.1, the widely adopted standard for pipe identification in industrial and commercial facilities. The Black on Yellow color scheme and directional arrows are fully compliant with the standard's requirements for flammable fluid piping systems.

Can the marker be removed and reused?
Yes — BradySnap-On markers can be removed from one pipe and reapplied in another area, making them a flexible and cost-effective solution for facilities that reconfigure piping systems.
