Wire Connector 16-14 AWG

These 3M Scotchlok butt splice connectors join two solid or stranded copper wires in the 16 to 14 AWG range. Each barrel is tin-plated copper with a brazed seam for mechanical strength. The pack contains 100 pieces for production or maintenance work.

Crimp-Only Termination

The connection is made by crimping with a compatible hand tool; no solder or insulation displacement is used. Barrel inside diameter is .09 in and overall length is .56 in. Rated for 600 V and temperatures up to 347 Degrees F with CSA and UL listings.

Bare Metal Finish

Supplied without insulation so the crimp can be visually inspected and covered with heat-shrink or tape as the installer chooses. Tin plating protects the copper barrel from oxidation during storage and service.

Questions about this item

What does the 16-14 AWG rating mean for the wires I can join?

It accepts solid or stranded copper conductors from 16 AWG up to 14 AWG, so each barrel fits that wire range without stepping down to a smaller gauge.

How does the 600 V rating limit the circuits I can use these on?

The UL and CSA listings cover up to 600 volts, so the splice is approved for standard low-voltage power and control wiring at or below that level.

What clearance do I need for the 0.56 inch barrel length when routing the finished joint?

Each connector is 0.56 inches long overall, so allow at least that much straight run plus room for the crimp tool to close fully around the barrel.
