Pica Dry Refill - 4070 Summer Heat - 8/pack

Pica-Dry Summer Heat 4070 – High-Temperature Precision

The Pica-Dry Summer Heat 4070 refill pack offers the perfect solution for professionals working in extreme climates or high-heat environments. While standard marking leads can soften or melt when temperatures climb, these specialized "Summer Leads" remain structurally sound and stable. Specifically, they withstand heat up to 150°F (70°C) without losing their form. 

Consequently, you can leave your marker in a hot truck or work on sun-baked materials without worrying about the lead failing.

Beyond their impressive heat resistance, these leads provide a water-resistant finish that secures your measurements against sweat and light rain. Because the formula is permanent, the marks stay visible on almost all surfaces, including wood, metal, and stone. However, users should note that these specific leads are not suitable for glassy or glossy surfaces. Instead, they truly excel on porous and rough materials where traditional leads might struggle.

Furthermore, the assorted pack offers color-coded versatility for different job site needs, allowing you to switch between graphite, red, and white for maximum contrast.

Why the Pica Dry Refill is an Essential: 

• Heat Stability: These leads maintain their integrity up to 150°F, preventing melting in toolboxes or under direct sunlight.

• Water Resistance: The permanent formula ensures your markings survive moisture, making them ideal for outdoor summer projects.

• Assorted Visibility: Each pack contains three graphite, three red, and two white leads to provide high visibility on dark or light materials.

• Universal Fit: The 2.8 mm diameter leads fit perfectly into the standard Pica-Dry Longlife Automatic Pencil.

• Tough Construction: Despite the heat, these leads offer the durability required for heavy-duty construction and industrial use.

Ultimately, the Pica Summer Heat Dry Refill set ensures that your productivity never drops just because the temperature rises. By choosing these temperature-stable refills, you protect your workflow from the common frustrations of summer heat.
