Heat Shrink Solder Butt Connector, 16–14 AWG, Blue, 5-Pack

The E-CON-HS4mm is a heat shrink solder butt connector designed for making secure, insulated wire splices in electrical and low-voltage wiring applications. Compatible with 16–14 AWG conductors, it uses a solder-lined heat shrink sleeve that bonds and seals the connection when heat is applied, eliminating the need for separate crimping tools. The connector is rated for 27A continuous current and accommodates wire cross-sections of 1.5–2.5 mm². The blue color coding corresponds to the 16–14 AWG range for quick identification during installation. The heat shrink sleeve provides both mechanical strain relief and moisture resistance once activated, protecting the joint against corrosion and incidental contact.
