MKL96821EA - Markal Valve Action Liquid Paint Marker, Yellow - Industrial Grade

High-Visibility Layout & Fabrication Marker

For professional welders and fabricators, clear and durable layout lines are essential for precision work. The Markal Valve Action Yellow Paint Marker provides the distinct visibility needed on dark steel, iron, and aluminum surfaces where soapstone or standard ink might fail. This marker dispenses real liquid paint, creating a bright, opaque line that stands out clearly against the base metal, ensuring that cut lines, drill points, and fit-up marks remain visible even under low-light workshop conditions or through a welding helmet lens.

The durability of the mark is paramount in a welding environment. This paint marker is formulated to resist wear, abrasion, and typical shop fluids like cutting oils and coolants. It dries quickly to the touch, preventing the loss of critical measurements due to accidental wiping or handling. The valve-actuated tip puts the welder in control of the paint flow; a simple depression of the tip saturates the fiber nib, allowing for smooth writing on cold rolled steel, rusty pipe, or structural beams. The lack of Xylene in the formula makes it a safer choice for enclosed shop environments compared to older industrial markers.

Specifically relevant to TIG welding and high-end fabrication, this marker is safe for use on stainless steel and exotic alloys. It is engineered to avoid introducing contaminants that could lead to pitting or corrosion, a critical factor when working with expensive materials or code-compliant pressure vessels. Whether you are marking out a complex blueprint on a table or labeling pipe spools for installation, the Markal Valve Action marker delivers the performance and reliability required by the welding trade.

Welding & Fabrication Benefits

• Bright yellow marks offer superior contrast on carbon steel and iron.
• Safe for stainless steel: will not cause corrosion or pitting.
• Marks hold up against water, oil, and UV exposure.
• Durable tip survives contact with rough, rusty, or ground surfaces.
• Temperature resistance range covers most ambient shop conditions.
