Bullet connectors make a quick plug-together connection for single wires: male bullets and female receptacles for 22-18 and 16-14 AWG wire in .157" and .180" sizes, with vinyl, nylon or adhesive-lined heat shrink insulation.
| Choice | Options |
|---|---|
| Wire gauge | 22-18 AWG (red), 16-14 AWG (blue) |
| Bullet size | .157" or .180" — the male and female must match |
| Insulation | Vinyl for dry interiors; nylon for vibration and engine bays; heat shrink to seal out water |
Put the female receptacle on the power (supply) side so the exposed male pin is not live when disconnected. For multi-wire plugs, see quick disconnects.
Only the heat shrink versions, which seal when heated.
No. Use a male and female of the same size.
