The DIVERSITECH 540-808 is an oil-based valve action paint marker in yellow, designed for permanent marking on most surfaces encountered in trade and service work. The oil-based paint formula dries quickly and delivers bright, opaque color that resists fading. A patented valve-operated feed mechanism controls paint flow, reducing bleed-out and skip. The medium point tip provides legible marks on pipe, conduit, sheet metal, concrete, and similar substrates. HVAC, plumbing, electrical, and general service technicians use this marker for labeling, color-coding, and job-site identification tasks.
This marker suits residential and commercial trade applications where a durable, weather-resistant mark is required. Common uses include labeling refrigerant lines, marking pipe runs, identifying circuit breakers, tagging equipment for service intervals, and color-coding components during installation or retrofit work. The quick-dry formula minimizes smearing when working in tight spaces or on overhead surfaces.
Designed for general-purpose marking on most trade surfaces including metal, PVC, concrete, and wood commonly found in HVAC, plumbing, and electrical service environments.
No installation is required for this marker. Before first use, shake the marker and press the tip firmly on a test surface to prime the valve feed mechanism. Store horizontally or tip-down when not in use to maintain consistent ink flow. Keep away from open flame during use, as oil-based paint markers are flammable before fully dry.
