Brady 4086-C Snap-On Pipe Marker — Yellow, 2-1/2"-3" OD (ANSI/ASME A13.1)
The Brady 4086-C is a yellow snap-on pipe marker designed for pipes with an outside diameter of 2-1/2" to 3". Made from Brady's B-915 vinyl material, it installs in seconds with a rigid clip that snaps directly onto the pipe — no tools, no adhesive, no strapping required. Yellow pipe markers identify flammable, combustible, and oxidizing fluid systems per ANSI/ASME A13.1.

ANSI/ASME A13.1 Pipe Marking Reference
Brady pipe markers are designed to meet ANSI/ASME A13.1, the standard for identification of piping systems in industrial and commercial facilities.
Color Coding by Fluid Class:
- Red — Fire protection (water, foam, CO₂)
- Orange — Toxic or corrosive fluids
- Yellow — Flammable, combustible, or oxidizing fluids (this marker)
- Gray — Steam or high-temperature water
- Green — Potable water, cooling water, cold water
- Blue — Compressed air
Size Selection by Pipe OD: Marker size must be appropriate for the pipe outside diameter to ensure legibility from a normal working distance.
Marker Placement Requirements:
- At all valves and flanges
- At all pipe penetrations through walls, floors, or ceilings
- At all direction changes
- Every 25–50 ft on straight runs (facility discretion)
