Liquid Electrical Tape – Waterproof UV-Resistant Rubberized Sealant

Liquid Electrical Tape – Fast-Drying Rubberized Insulation Sealant

Protect wires, cables, and electrical connections with this professional-grade Liquid Electrical Tape. Formulated from liquid rubber insulating adhesive, this 5-ounce tube brushes on smoothly and cures into a durable, flexible rubberized coating that seals out moisture, resists UV rays, and withstands high temperatures — all in a convenient, no-mess tube format.

Perfect for wire repair, automotive wiring harnesses, marine electrical systems, and everyday household electrical projects, this liquid tape replaces traditional roll tape in hard-to-reach spots and irregular surfaces where wrapping is nearly impossible.

Key Features

• Fast Drying: Touch-dry quickly; fully cures in approximately 4 hours for a reliable, lasting seal.
• Waterproof & Moisture-Resistant: Creates an airtight rubberized barrier that keeps water, humidity, and corrosion away from exposed conductors.
• High-Temperature Resistance: Engineered to hold up under elevated heat conditions common in automotive and industrial environments.
• UV-Resistant Coating: Withstands prolonged sun exposure without cracking, peeling, or degrading — ideal for outdoor and marine use.
• Flexible & Durable: Once cured, the rubberized coating flexes with cables and wires, preventing brittleness and maintaining a secure seal.
• Easy Brush-On Application: Integrated applicator lets you coat wires, splices, connectors, and terminals precisely — no waste, no mess.
• Versatile Use: Suitable for wire repair, automotive, marine, and household electrical applications on plastic and similar surfaces.
• Black Finish: Blends seamlessly with most standard wire insulation colours.

Frequently Asked Questions

Q: How do I apply liquid electrical tape to a wire splice?

A: Clean and dry the wire or connector surface first. Using the integrated brush applicator, apply an even coat of the liquid electrical tape over the splice or exposed conductor. Allow it to dry to the touch, then apply a second coat for maximum insulation. Full cure takes approximately 4 hours. The result is a flexible, waterproof rubberized seal.

Q: Can this liquid electrical tape sealant be used outdoors or in marine environments?

A: Yes. The rubberized coating is both UV-resistant and waterproof, making it well-suited for outdoor wiring, boat wiring, and marine electrical connections where moisture and sun exposure are ongoing concerns.

Q: Is this product safe on automotive wiring under the hood?

A: Absolutely. This liquid electrical tape is specifically formulated with high-temperature resistance, making it suitable for automotive under-hood wiring harnesses, terminals, and connectors that may be exposed to engine heat.

Q: How long does a 5-ounce tube last?

A: A 5-ounce tube covers a generous number of wire repairs, splices, and connector seals depending on application thickness. For best results, seal the tube tightly after each use to extend shelf life.
