Terminal for 18 AWG wire

The 3M MNG18-10R/LX is a nylon-insulated ring terminal built for 18 AWG copper conductors. It accepts wires from 22 AWG up to 18 AWG and fits a #10 stud. The barrel has a 0.07 in inside diameter and a 0.25 in length with a butted seam. It is UL Listed and CSA Certified for 1,000 V maximum voltage.

Crimp connection under load

The tin-plated copper barrel creates a secure crimp joint that resists vibration when installed with the correct tool. Nylon insulation withstands temperatures up to 221 Degrees F without melting. Partial coverage leaves the barrel exposed for visual inspection of the crimp. The butted barrel style maintains consistent contact pressure during thermal cycling.

Check wire gauge and stud size

Verify that your conductor falls between 22 AWG and 18 AWG before ordering. Confirm the mounting point uses a #10 stud so the 0.31 in tongue width aligns correctly. Ensure your crimping tool matches the butted barrel profile for a reliable termination. This terminal is not suited for wires larger than 18 AWG or smaller than 22 AWG.

Questions about this item

How hot does the nylon insulation get when the terminal runs at its 1000 V rating all day?

The insulation is rated for a maximum temperature of 221 degrees F, so it remains stable under continuous 1000 V operation.

What crimp tool and wire gauge do I need to install this #10 stud ring terminal?

Use a crimp tool sized for 18 to 22 AWG wire; the barrel accepts 0.07 in diameter and 0.25 in length for a secure butted connection.

Will this tin-plated copper terminal corrode when paired with older copper building wire in a fixture?

The tin finish protects the copper barrel, and the terminal is UL Listed and CSA Certified for use with building wire, fixtures and luminaires.
