Ecm Industries Llc LTB-400 Liquid Electrical Tape 4 Oz

Product Description

The ECM INDUSTRIES LLC LTB-400 is a black, rubber-based liquid electrical tape designed to insulate, seal, and protect electrical connections in demanding environments. Packaged in a 4 oz transparent plastic bottle, this coating applies at 5-7 mils per coat and delivers 200 volts per mil of dielectric protection. The rubber-based formula remains flexible after curing and will not harden, unravel, or become brittle in extreme weather conditions. Electricians, low-voltage installers, and field technicians use it as a fast, brush-on insulation solution where traditional tape is impractical or insufficient.

The LTB-400 is suited for both indoor and outdoor applications. Common use cases include insulating exposed cables and splices, protecting underground wiring, waterproofing outdoor lighting connections, and securing wiring on utility trailers, alarms, and security systems. Its waterproof, weatherproof barrier makes it a reliable choice wherever moisture or temperature swings are a concern. The product is sold in units of one each.

Installation Notes

Installation should be performed by a qualified electrician or low-voltage technician in accordance with applicable NEC requirements. De-energize and lock out the circuit before applying any coating to electrical connections. Allow each coat to cure fully before applying additional coats or restoring power. Ensure surfaces are clean and dry prior to application for proper adhesion.
