3M Highland Nylon Fully Insulated Female Disconnect Terminal, AWG 22-18

The 3M Highland Nylon Fully Insulated Female Disconnect Terminal is a quick-connect wire terminal engineered for AWG 22-18 conductors. Its fully insulated nylon housing surrounds the crimp barrel and terminal shank, helping protect the connection point from abrasion, moisture intrusion, and accidental contact during installation and service. The female disconnect configuration mates with a standard male tab, giving technicians a fast, tool-free way to connect and disconnect circuits for maintenance, troubleshooting, or component replacement. Each package contains 25 terminals per bag, making this a practical, ready-to-use option for electrical panels, equipment wiring, and general repair work where AWG 22-18 conductors are common.

Key Features

  • Wire Range: Sized for AWG 22-18 conductors, matching common control, signal, and low-current branch wiring.
  • Fully Insulated Nylon Housing: Nylon insulation fully covers the crimp barrel and terminal shank, shielding the connection from abrasion and incidental contact with adjacent components.

3M FDI18-250Q – Frequently Asked Questions

1) What wire size does the 3M Highland FDI18 female disconnect terminal accept?
The Highland FDI18 is sized for AWG 22-18 stranded or solid conductors, which covers most control, signal, and low-current branch wiring. If your conductor is 16 AWG or larger, this barrel is too small and you need the next wire-range terminal up in the Highland line.
2) Is the FDI18 insulation nylon or vinyl, and does that matter for panel work?
Nylon, and it matters. The Highland FDI18 uses a fully insulated nylon housing that covers both the crimp barrel and the terminal shank, so it holds up better to abrasion and pull-through in a tight wireway than a soft vinyl sleeve, and it keeps the metal shielded from incidental contact with adjacent components.
3) Do I need a special crimper for the 3M Highland FDI18 disconnect?
It is a crimp-style terminal installed onto a stripped conductor end, so you need a crimping tool, not a solder joint or screw. Use the insulated-terminal nest of a standard terminal crimper sized for the 22-18 AWG range (commonly the red color-code position). The disconnect itself is tool-free once crimped, it pushes on and pulls off the male tab.
4) Should I use a female disconnect or a ring terminal for equipment wiring?
Pick the female disconnect when the circuit gets broken for service: a motor, switch, relay, or control component you expect to swap or troubleshoot. It pushes onto a mating male tab and pulls off by hand, no tools. Use a ring or fork terminal instead where the wire lands on a screw stud and is meant to stay put, since a ring cannot back off under vibration the way a push-on can if it is not fully seated.
5) How many 3M Highland FDI18 terminals come in a bag?
25 terminals per bag. That bag count is the ordering unit, so a panel build needing a few hundred disconnects means ordering multiple bags.
6) Where is the 3M Highland FDI18 terminal made?
United States. For public agency, federal, or institutional buyers working under domestic-sourcing requirements, the Highland FDI18 is listed with a United States country of origin.
7) Can I use the FDI18 on automotive harness repairs as well as building control panels?
Yes on both. The Highland FDI18 is used in automotive and industrial wiring harnesses, control panel and equipment wiring, quick-disconnect service points, and general electrical repair, anywhere the conductor falls in the 22-18 AWG range.
