Heat Shrink Ring

Ancor Heat Shrink - connectors offer heat activated adhesive built into the sleeve of the heat shrink tubing. When heated, these connectors form a water tight seal and the ultimate vibration and strain relief.

High-quality ring terminals for connecting electrical and battery wires to battery lugs, lithium battery bolts or, for example, bus bars. With a heat gun or a gas torch, you can shrink the terminal watertight and make the connection sturdy. The ring terminal is tinned and of very high quality and will not oxidize even over years. When you crimp the terminal and heat it watertight, your wire will not come loose from the terminal.
