The MARKAL 96664 is a Stylmark tube marker designed for marking pipes, conduit, metal, and other trade surfaces where a clean, visible line is required. The marker uses a metal ball tip measuring 3/16 inches in diameter, delivering consistent ink flow and durable marks on smooth or slightly rough surfaces. The ink color is white, making it suited for marking on dark-colored pipe, black conduit, and coated metal. HVAC technicians, plumbers, electricians, and pipefitters use tube markers like this one for layout work, labeling, and service marking in the field and in the shop.
The 96664 is appropriate for both residential and commercial trade applications. Common uses include marking refrigerant line sets, drain lines, conduit runs, and structural steel prior to cutting or drilling. The white ink provides strong contrast on galvanized, black iron, PVC, and painted surfaces. The tube-style body keeps the marker compact and easy to carry in a tool pouch or service bag.
Designed as a general-purpose trade marker compatible with standard marking applications on pipe, conduit, sheet metal, and structural materials.
No installation is required for this marking tool. Store the marker cap-down or horizontally when not in use to maintain ink flow at the tip. Replace the cap after each use to prevent the tip from drying out. Surface preparation such as wiping away grease or moisture improves mark adhesion and legibility.
