Pica Dry Refill - 4070 Summer Heat - 8/pack

Pica-Dry Summer Heat 4070 Refill | High-Temperature Marking

The Pica-Dry Summer Heat 4070 refill pack is the ultimate solution for professionals working in extreme climates or high-heat environments. While standard marking leads soften or melt as temperatures climb, these specialized "Summer Leads" remain structurally sound and stable. Engineered to withstand heat up to 150°F (70°C), these leads won't lose their form in hot trucks or on sun-baked job sites.

Beyond heat resistance, these leads provide a water-resistant, permanent finish that secures your measurements against sweat and light rain. They excel on porous and rough materials where traditional leads struggle, ensuring your workflow never stops just because the temperature rises.

Why the Pica-Dry Summer Heat 4070 is Essential

• Maximum Heat Stability: Leads maintain structural integrity up to 150°F, preventing melting in toolboxes or under direct sunlight.

• Weatherproof Performance: The permanent formula ensures markings survive moisture and heavy perspiration during outdoor summer projects.

• Assorted High-Visibility: Each pack contains graphite, red, and white leads for maximum contrast on both dark and light materials.

• Universal Tool Fit: Designed with a 2.8 mm diameter, these leads fit perfectly into the standard Pica-Dry Longlife Automatic Pencil.

• Heavy-Duty Durability: Optimized for the rigors of construction and industrial use, offering the toughness required for rough surfaces.

Engineered for Extreme Industrial Climates

The Pica-Dry 4070 Refill set represents a commitment to job-site efficiency, even in the blistering sun. By choosing these temperature-stable refills, you eliminate the common frustrations of crumbling or "bleeding" marks caused by heat-softened wax. Whether you are marking timber, metal, or stone, these leads provide the reliability needed for high-stakes layouts.

Color-Coded Versatility for Every Surface

This assorted pack offers the flexibility to switch between colors for maximum visibility. Use the white or red leads for dark metal and stone, or the graphite for traditional layout work. Note: These specific high-heat leads are optimized for porous surfaces and are not recommended for glassy or glossy materials.

Pro Tip: Keep a pack of Summer Heat refills in your vehicle's glove box or dashboard tray—places where standard markers typically fail—to ensure you always have a functional tool ready to go.
