The 3M™ Performance Plus Wire Connector electrically connects two or more conductor ends in a pigtail application and insulates the connection. It combines a very small shell with an increased wire range. The spring bites wire quickly with less effort, and the small shell fits easily into tight spaces, while its flexible skirt helps protect workers from contact with over stripped wires.

They are available in five color/wire range options: O/B+ (orange/blue) 2 #22 - 3 #12 AWG; T/Y+ (tan/yellow) 2 #22 - 3 #12 AWG; R/Y+ (red/yellow) 2 #18 - 2 #8 AWG; T/R+ (tan/red) 2 #18 - 5 #12 AWG; B/G+ (blue/gray) 4 #14 - 2 #6 AWG.
