Sta-Kon RA23 INS NYLON WRISTLCK DISC 22-18 RED

The RA23 is sized for 22-18 AWG stranded wire, which is what the red insulation color signals on Sta-Kon terminals. Keep the conductor inside that range; crimping a 16 AWG conductor into a red barrel will not form a reliable crimp and an 18 AWG-plus wire in a blue (16-14) barrel will pull out.

The RA23 is a wristlock disconnect terminal in the 22-18 AWG red range. Wristlock disconnects mate as a pair, so order the matching opposite-gender half in the same red 22-18 size if you are building both ends of the connection. Both halves use the same nylon insulation and crimp the same way.

Nylon, or polyamide, is the insulation on the RA23, and it is the tougher of the two common choices. Nylon resists abrasion and cut-through from pulling a harness through a raceway and tolerates higher heat than PVC/vinyl sleeves, which is why it gets specified for motor leads, control panels and appliance work. Vinyl is the cheaper option for benign indoor low-heat use.

Order by manufacturer part number RA23, a Sta-Kon nylon insulated wristlock disconnect for 22-18 AWG in red. One part number covers it, so a facility or MRO buyer standardizing a crib on small-gauge control wiring can stock the single number rather than a size matrix.

A wristlock disconnect like the RA23 is for connections you expect to break, such as pulling a motor, a limit switch or a control device out for service without cutting wire. Ring and fork terminals land under a screw or stud and are the right choice for permanent terminal-block and lug terminations. If the joint has to separate in the field, the disconnect wins; if it bolts down and stays, use a ring tongue.

Brass is the barrel material. Brass crimp barrels are standard on disconnects and carry current fine for the 22-18 AWG range the RA23 serves; the thing that decides long-term resistance is crimp quality, not the alloy. Use a ratcheting crimper matched to the red insulated die so the barrel is fully compressed around the strands.

Country of origin on the RA23 is the United States. That matters on government, institutional and federally funded work where domestic-content language sits in the spec, and it is a question that comes up more on electrical consumables than most buyers expect.
