Permatex 85120 Liquid Electrical Tape – 4 oz, Black | Weatherproof Wiring Sealant

Overview

Permatex 85120 Liquid Electrical Tape provides a weatherproof shield for wiring and electrical connections. It starts as a liquid and dries to a flexible vinyl polymer, forming a durable barrier that resists dirt, dust, chemicals, and moisture. This helps keep electrical joints protected in outdoor, automotive, and damp environments, without the need for bulky tapes or sleeves.

How it works

Applied with a brush-top applicator, the coating flows smoothly over wires and terminals, filling irregular gaps and leaving no exposed edges. As it cures, it remains flexible enough to move with temperature changes and vibration, helping maintain a continuous seal over time.

Key benefits

• Flexible vinyl polymer forms a resilient barrier around connections

Tip: For best results, apply a thin, even coat to clean surfaces and allow adequate drying time before exposure to the elements. The brush-top design helps reach intricate joints and tight spaces that other protectants may miss. Consider this solution when you want a single-step protection that stays put in challenging environments.
