12-10 to 16-14 AWG Step Down Butt Yellow Heat Shrink

This butt splice connector is used to connect different gauge wires (or multiple wires of the same size) together. This also has heat shrinking ends, which contract around the wires when exposed to heat, leading to a better seal between the wires and butt splice connector. A solid product for electrical applications in the auto, construction and electrical industries. (VBUTTYSDHS)
