Compressed air identification

The Brady 4034-D pipe marker identifies compressed-air lines in industrial and commercial facilities. A blue background with white legend text and directional arrows provides clear visual indication of pipe contents and flow direction. The snap-on mounting style allows installation without tools or system shutdown.

Maintenance teams and plant operators

Maintenance teams and plant operators who need durable, legible marking for compressed-air piping will find this marker suitable. Facilities requiring markers for other fluids, gases, or custom legends should select a different Brady model. The product is restricted from sale in certain states, so buyers in those locations must choose an alternative.

Snap-on mounting style

The snap-on mounting style is the single specification that determines whether this marker fits the intended pipe. It clamps directly onto the pipe exterior without adhesives or fasteners, so the pipe diameter must fall within the 4034 size range for a secure fit. Verify the pipe outer diameter matches this range before ordering.

Questions about this item

Will the snap-on mounting stay secure or need replacement?

The snap-on design lets you remove and refit the marker without tools, so the same unit can be reused if pipe layout changes.

What limits visibility on a 4-to-6-inch pipe over time?

The 1 1/4-inch character height on a blue background is sized for that pipe range; dirt or paint overspray on the surface is the first thing that reduces legibility.

Does the plastic marker add heat or noise to the compressed-air line?

No — it is a passive plastic label that clamps on the outside of the pipe, so it neither generates heat nor creates noise.
