Sta-Kon BB2SP BARE SPLICE 16-14 AWG SILVER FINISH

The BB2SP bare butt splice is sized for 16-14 AWG conductors. Both ends take the same range, so it joins 16 to 16, 14 to 14, or 16 to 14. For 22-18 AWG or 12-10 AWG runs you need a different barrel size, since crimping an undersized or oversized conductor in this barrel will not hold mechanically.

It is a non-insulated (bare) barrel, so insulation is on you. Standard practice is heat-shrink tubing or electrical tape over the finished crimp. Bare splices are the right choice when you want to shrink-sleeve to your own spec, when the splice goes inside a sleeve or boot, or where high temperature rules out a factory nylon or vinyl insulator.

The barrel is copper, which is what you want for stranded copper conductors, standard in building wire and control wiring. It is not an aluminum or bimetallic connector, so do not use it to terminate aluminum conductors.

For panel work where conductors are bundled and you want color-coded size identification at a glance, an insulated nylon or vinyl butt splice is faster and needs no second step. The BB2SP bare copper splice makes more sense when you are sleeving the joint in heat shrink for strain relief or moisture, when the splice sits inside an existing boot, or in a location where you do not want plastic insulation. Either way the conductor range here is 16-14 AWG.

Yes, a crimp tool, not pliers. Because the barrel is bare rather than insulated, you crimp on the metal itself and need a die or nest matched to a non-insulated 16-14 AWG barrel. Each end gets its own crimp. Insulated-terminal crimpers with color-coded nests are not the correct nest for a bare barrel.

Order Sta-Kon BB2SP. That is the manufacturer part number for the bare 16-14 AWG butt splice with the silver finish, and it is the single model offered under that name, so there are no finish or size options to specify.

Country of origin on the BB2SP bare splice is the United States, which covers Buy American style documentation requests on federal, school, and healthcare jobs.
