[EXECELLENT QUALITY] - Direct factory with excellent quality control, STRONG & DURABLE. The copper core of our heat shrinkable joints is made of high quality tinned copper, in addition to being extremely conductive, it is easier to flatten and grip the wire.

[Practical Design]: Double-wall design, outer layer of polyolefin tube, inner layer of hot melt adhesive, precise crimping and good contact. Electrical butt connectors provide high tensile strength and adequate hot melt adhesive inside the tube. After shrinking, the wiring is firm and not loose, and it can ensure that the current continues to flow smoothly.

[EASY USE] - Take two wires you wish to join. Remove the wire insulator, pick the terminal color you want. Insert the wire into the terminal one at the time and crimp by crimping tool, insert another terminal and crimp. Use air gun to apply heat on the heat shrink connectors

[Wide Applications]: Our waterproof terminals are perfect for marine, automobile applications, electrical and electronics industries. Whether working on your Boat, Vehicle, Home, or Scientific project, the electrical crimp connector will ensure a strong waterproof seal to make sure everything bonds correctly

[Package Included]: 25 pcs red connector ( 22-16 AWG ), 15 pcs blue connector ( 16-14 AWG ), 10 pcs yellow connector ( 12-10 AWG ).
