The DYKEM 44371 is a broad-point, water-resistant marker designed for marking on metal, pipe, conduit, fittings, and other trade surfaces. The broad tip lays down a visible line quickly across rough or coated materials. Water-resistant ink holds up in damp conditions, making it practical for job sites where surfaces may be wet or exposed to moisture during installation. Green ink provides high contrast on dark or bare-metal surfaces. Technicians in HVAC, plumbing, and mechanical trades reach for this marker when tagging components, labeling pipe runs, or indicating cut lines before fabrication.
The 44371 is suited for use in residential and commercial trade environments. Typical applications include marking refrigerant line sets, copper or black iron pipe, electrical conduit, sheet metal ductwork, and structural members prior to cutting or drilling. The water-resistant formulation makes it a dependable choice for outdoor rough-in work and wet utility areas where standard markers fail to hold.
Designed as a general-purpose industrial marker suitable for use on metal, plastic, pipe, conduit, and similar trade surfaces commonly encountered in HVAC, plumbing, and electrical work.
No power shutoff or special tooling is required for use. Ensure the cap is fully seated after each use to prevent the tip from drying out. Avoid applying the marker directly over cutting tool paths where ink residue could affect measurement accuracy. Store horizontally or tip-down to maintain ink flow to the broad tip.
