<p>If you are worrying about the security and the conductivity of heat shrink butt connectors in the market. Then our heat shrink butt connector can give you a peace of mind. Judging from security, our material, the external tube of our heat shrink butt connectors adopt high-grade PE and hot-melt material, which is waterproof, corrosion proof, shockproof, anti-oxidation and durable and from conductivity, the internal barrel of our heat shrink butt connectors are made of premium copper material, which greatly prevents wiring failures and reduces equipment downtime, by increasing current flow and decreasing voltage drop. Additionally, our heat shrink butt connector is economic and use-friendly by including 125 pcs with 50red, 50blue and 25yellow (Red: A.W.G 22-16, Blue: A.W.G 16-14, Yellow: A.W.G 12-10), which is easy for you to choose the correct connector to connect your cable or conductor. </p>
