The NEWELL BRANDS SAN1920937 is a pack of 36 Sharpie Fine Point permanent markers in red, designed for trade and professional use where clear, durable markings are required on job sites, equipment, and components. The fine-point tip delivers consistent, thin lines suited for labeling pipe, conduit, panels, and other hard-to-mark surfaces. Alcohol-based ink dries quickly, resists fading, smearing, and water exposure, and is rated AP nontoxic certified. Each pen-style marker is built for repeated daily use in demanding environments.
These markers are commonly used by HVAC technicians, plumbers, electricians, and pool service professionals for marking refrigerant lines, pipe measurements, wire runs, circuit labels, and equipment tags. The fine point allows legible markings in tight spaces. The 36-unit pack format supports stocking a service van, shop bench, or job-site supply kit without frequent reordering. The red color provides high contrast on light-colored surfaces, making labels easy to read at a glance.
Designed for general-purpose permanent marking on hard surfaces including metal, plastic, glass, and coated materials commonly encountered in HVAC, plumbing, electrical, and pool service applications.
No installation is required for this product. When marking near live electrical components or gas lines, ensure all appropriate lockout/tagout procedures are followed before service work begins. Allow ink to dry fully before covering marked surfaces with tape, insulation, or protective coatings to ensure marking legibility is preserved. Store markers horizontally with caps secured to maintain tip condition and extend service life.
