About This

Thick Tinned Copper Core: The heat shrink wire connectors utilizes seamless, thick tinned copper tubing (99.9% purity) for excellent conductivity, ensuring a secure crimp every time. Its sturdiness and durability help you work better.
Watertight and Lasting use: The connector's heat shrink tubing is made from a polyolefin and hot-melt adhesive compound. Upon heating, the adhesive melts inside, shrinking rapidly and adhering to the wire insulation, creating a watertight, corrosion-restricted seal that guards against the connection in harsh environments.
More stable connection: The heat shrink tubing for the wire connectors features a double-wall design with a 3:1 shrink ratio. It restricts stretching, deformation and breakage, offers shock hindrance, and a longer service life.
Easy Identification: The terminals connectors are marked with wire gauge markings for easy identification, helping you quickly select the right connector.
Quantity and Wide usage: The package contains 1,000 blue heat shrink butt connectors. They are suitable for AWG 16-14 wire and can meet daily use and replacement, which are suitable for automotive, marine, electrical, industrial, and home wiring.
