3M MV10BCX – Frequently Asked Questions

1) What wire sizes do the 3M Scotchlok vinyl butt connectors cover?
Two wire ranges are offered: 22-18 AWG in red (MV18BCX) and 12-10 AWG in yellow (MV10BCX). The color coding is the standard AWG convention, so red barrels take the small stranded conductors and yellow takes 12 and 10 gauge. Pick the barrel that matches the gauge you are splicing; an oversized barrel will not hold a crimp.
2) Can I splice a 12 AWG wire to an 18 AWG wire with one of these?
No. Each butt connector is built for a single gauge range, either 22-18 AWG (red) or 12-10 AWG (yellow), and the barrel diameter and crimp die are sized to that range. Splicing two very different gauges in one barrel leaves the smaller conductor loose. Use a step-down connector or a terminal block for a mixed-gauge joint.
3) Will a Scotchlok butt connector work on solid wire or only stranded?
These are specified for stranded wire. The 12-10 AWG yellow connector is described for 12-10 AWG stranded wire applications, and the barrel crimps down onto the conductor bundle. For solid conductors in a panel or junction box, use a connector rated for solid wire instead.
4) What does the wire stop inside the connector actually do?
There is an internal stop midway in the barrel, so each conductor can only be pushed in to the correct depth from its own end. That keeps both wires centered under the crimp die instead of one running past the middle and leaving the other with almost no metal engaged. Strip, push each wire in until it hits the stop, then crimp.
5) How hot can these butt connectors run in an HVAC or equipment application?
The vinyl insulated Scotchlok butt connector is rated to a maximum operating temperature of 105 degrees C. That covers typical HVAC control and power wiring, motor and machinery terminations, and automotive engine-bay work. Above that, move to a higher-temperature nylon or heat-shrink insulated connector.
6) Do I need a special crimper for the 3M Scotchlok butt connectors?
Yes, a crimping tool with the correct die for the barrel size. The connector is crimped, not twisted or soldered, so the die has to match the gauge range you are working with (red 22-18 or yellow 12-10). After crimping, tug both conductors to confirm the splice holds.
7) Are these connectors OK for marine or damp-location splices?
The barrel is electrolytic copper with tin plating for corrosion resistance, and marine wiring is listed among the applications. Be aware the insulation is vinyl, not adhesive-lined heat shrink, so it is not a sealed splice. For a submerged or continuously wet run, use a heat-shrink sealed butt connector instead.
8) How long is the yellow 12-10 AWG butt connector, and how much wire do I need to leave?
Overall length on the 12-10 AWG yellow connector is 1.2 inches. Since the wire stop sits mid-barrel, each conductor only travels about half that distance, so you need very little slack on each side to make the splice, useful when repairing a short pigtail in a tight junction box.
9) How are the Scotchlok butt connectors packaged for shop stock?
They come in a 50-piece bottle, which is a practical MRO or service-truck quantity, and the bottle keeps the loose connectors together rather than loose in a bin. Measurements given are 4.375 in and 1.625 in on the package.
