Sta-Kon RAAS22X – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RAAS22X butt splice take?
The RAAS22X is sized for 22 to 18 AWG stranded copper conductors, and the red insulation is the standard color code for that range. Both ends take the same range, so it joins 22-18 to 22-18. For 16-14 AWG you need the blue-coded size instead, and for 12-10 AWG the yellow.
2) Is this butt splice rated for a 600V circuit?
Yes. The RAAS22X carries a 600 V rating, which covers general line-voltage branch circuit and control wiring as well as low-voltage work. It is UL recognized under file E9809.
3) Can I use a heat shrink butt splice near a motor or in a hot mechanical room?
The RAAS22X is rated to 150 degrees C, so it holds up in high-ambient spots like motor leads, rooftop units, and boiler rooms where a standard vinyl-insulated splice would be marginal. The shrink sleeve also seals the joint against moisture, which is why these get specified outdoors and in wet locations rather than plain nylon barrel splices.
4) Do I need a special crimper, or will any tool work on these splices?
Crimp it with a tool matched to the 22-18 AWG insulated-barrel range, then shrink the sleeve with a heat gun. Two steps, two tools. Pliers will deform the copper barrel without forming a proper crimp, and a torch overheats the sleeve. The barrel is copper, so a controlled crimp is what makes the connection, not the sleeve.
5) Heat shrink butt splice or a regular nylon butt splice for low-voltage control wiring?
Use the heat shrink type, like the RAAS22X, anywhere the joint can see water, washdown, vibration, or high ambient heat: exterior fixtures, pump and irrigation controls, rooftop equipment, vehicle and trailer wiring. A plain nylon or vinyl barrel splice is fine for dry indoor junction boxes and is quicker since there is no heat step. The deciding factors here are the sealed sleeve and the 150 degree C rating.
6) Will a heat shrink butt splice work for repairing a cut thermostat or doorbell wire?
Yes, that is a good fit. Thermostat and low-voltage signal wire is typically 18 AWG, inside the 22-18 range this splice covers, and the sealed sleeve keeps the repair from corroding in an attic or crawlspace. Strip both ends, crimp one into each side of the barrel, then shrink. Do not twist the two conductors together first; the barrel needs clean straight ends.
7) What is the part number to reorder these red Sta-Kon splices, and where are they made?
Order Sta-Kon RAAS22X. It is the 22-18 AWG red heat shrink butt splice, 1.5 length, made in the United States.
