Heat Shrink Bullet Connectors Kit

A butt splice is permanent — the two wires become one joint. A bullet is a male and a female half that push together, so the join is a disconnect point you can pull apart later without cutting anything.

A standard crimping tool. Strip the wire, seat it in the barrel, crimp, then heat the sleeve to shrink it down over the crimp. No soldering iron and no die set.

Yes — that is the point of them. Pull the male half out of the female half as often as you need. If both halves are undamaged you can re-crimp and reuse them; check the insulation and the crimp before you do.

Red 22–16 AWG, Blue 16–14 AWG, Yellow 12–10 AWG. 10 AWG is the largest wire these take.

The heat shrink insulation draws down over the crimp and the wire insulation, which keeps moisture and dirt off the metal. Heat both halves properly and the connection is protected at the joint.

Anywhere you will want the circuit apart again — removing a panel, pulling a light off a trailer, swapping a component, or testing a run before you commit to it.

Yes. The barrels are thick copper and the crimp plus the shrink sleeve keep the joint from working loose, which is what makes them suited to vehicles, motorcycles and boats.
