Proxicast Pro-Grade 30mil Weatherproof Self-Fusing Silicone Tape – 1.5-in x 15-ft (Black)

Overview

Meet a rugged, ready-to-use sealing solution for outdoor and utility tasks: the Proxicast Pro-Grade 30mil Weatherproof Self-Fusing Silicone Tape. This thick, black tape is designed to seal coaxial cables, electrical connections, hoses, and small leaks without relying on messy glue. When you wrap, the tape fuses to itself, creating a durable, flexible bond that adapts to changing temperatures and weather conditions. It’s built to stay tight where moisture, dust, and corrosion are common, offering a practical, on-hand fix for everyday repair needs.

Rather than a traditional adhesive layer, this seal relies on self-fusing silicone that bonds to itself. The result is a clean application with no sticky residue upon removal, making temporary repairs more convenient and less messy. The roll’s 1.5-in width and 15-ft length provide ample material for multiple wraps on a single project, and the classic black finish blends with most outdoor setups.

Key benefits

• Thicker, wider, and stronger than many self-fusing silicone tapes, delivering robust protection.
• No messy adhesive or glue—tape sticks only to itself and leaves no residue when removed.
• Fully waterproof with resistance to UV exposure, saltwater, chemicals, and temperature changes.
• Activates with stretching: you can extend the wrap up to three times its initial length to set the seal.

Ideal uses and practical steps

• Seal outdoor antenna coax and electrical connections from moisture, dust, and corrosion.
• Create temporary, weatherproof seals for hoses and pipes during leaks or repairs.
• Use as a quick emergency fix on damaged cables or fittings when a permanent solution isn’t immediately available.
• Easy application process with no mess—watch the installation video in the photo gallery to see the technique.

How to use

• Clean and dry the area to be sealed before wrapping.
• Start wrapping and gently stretch the tape to activate its self-fusing properties.
• Wrap evenly around the target area, overlapped to form a tight, continuous bond.
• Press firmly to ensure full contact with itself; the seal should feel secure once finished.

For outdoor projects that demand reliability, this tape offers a practical balance of strength, flexibility, and ease of use. It is a convenient, non-permanent option for field repairs and maintenance tasks, and it is designed to perform across a range of challenging conditions.
