Sta-Kon RB14D INS NYLON WRISTLOCK DISC 16-14 BLUE

The RB14D is sized for 16-14 AWG stranded or solid copper wire. Blue is the standard color code for the 16-14 range, so the blue nylon body is a quick visual check on the bench that you grabbed the right barrel for 16 or 14 gauge conductors. For 22-18 AWG you need the red-coded size, and for 12-10 AWG the yellow one.

The RB14D is a receptacle (female) wristlock disconnect, the half that accepts the mating tab. To build a complete separable connection you also need the plug (male) half crimped on the other conductor. Order both halves in the same 16-14 blue size so the barrels match your wire.

Nylon/polyamide, not vinyl. Nylon takes more abuse during crimping and pull-through than a vinyl sleeve, and it holds up better where terminations get flexed or dragged through conduit and panels. The conductive barrel underneath is brass.

Use a crimp tool matched to insulated 16-14 AWG terminals. The RB14D is a nylon insulated brass barrel, and an insulated-terminal die set compresses the barrel without splitting the nylon sleeve the way an uncontrolled plier crimp can. The blue color code on the terminal corresponds to the 16-14 nest on most color-coded crimpers.

Wristlock style disconnects are used where you want a positive locking engagement that will not vibrate apart, such as motor leads, HVAC unit wiring, appliance harnesses, and control panel jumpers that get disconnected for service. The RB14D gives you a separable 16-14 AWG connection you can pull apart by hand for troubleshooting instead of cutting and re-splicing.

Country of origin on the RB14D is the United States, which matters if you are filling a government, institutional, or federally funded job with domestic sourcing requirements on electrical components.

Order it as Sta-Kon RB14D. That single number covers the blue nylon insulated wristlock disconnect for 16-14 AWG wire, so it is what you quote for restocking a service van or panel shop bin.
