3M MNG18-8R/LX Ring Terminal

This 3M ring terminal accepts 18 to 22 AWG wire and carries a 1,000 V rating for industrial and automotive wiring. The nylon-insulated barrel uses a butted crimp style with tin-plated copper contacts. It is CSA certified and UL listed for compliance. Suitable for panel builders and maintenance technicians needing a secure stud connection.

#8 Stud Size and 18 AWG Maximum

The terminal fits a #8 stud and handles wire up to 18 AWG as its largest conductor size. Barrel inside diameter measures .07 in and barrel length is .25 in for proper crimp engagement. Tongue width is .31 in to match the stud. This specification decides whether the lug fits the terminal block or busbar in your assembly.

Partial Nylon Insulation and Crimp Termination

Red nylon provides partial insulation coverage and withstands 221 degrees F maximum operating temperature. The crimp termination style requires a suitable hand tool or hydraulic crimper for a gas-tight joint. No additional hardware or software is bundled with the terminals. Buyers needing fully insulated sleeves or solder-style lugs should select a different part number.

Questions about this item

What does the 1000 V rating mean when the terminal is crimped in a live circuit?

It is the maximum voltage the nylon insulation is designed to withstand without breaking down, so the connection stays isolated up to 1000 V.

The terminal is UL Listed and CSA Certified — what does that cover in practice?

Those marks confirm the crimp barrel and insulation meet the safety and construction requirements of the relevant North American wire-connector standards.

Will the .31 in tongue width fit a standard #8 mounting stud?

Yes, the .31 in tongue is sized for a #8 stud and the barrel accepts 18 to 22 AWG wire with a .07 in inside diameter and .25 in length.
