Grote 83-2618 Butt Splice Connector

The Grote 83-2618 is a heat-shrink butt splice connector designed for 18 AWG maximum wire size and supplied in a 100-pack. It suits automotive electricians and installers who need a sealed, soldered joint for low-voltage wiring repairs.

Upgrade from crimp-only terminals

These connectors replace standard crimp terminals by adding a factory-soldered seam and adhesive-lined heat-shrink insulation in one step. The jump is worth it when vibration, moisture or temperature cycling would loosen or corrode a crimp-only connection over time.

Behaviour under sustained load

The soldered seam maintains consistent contact resistance while the polyolefin sleeve remains sealed from -67 °F to 230 °F. Rated for 600 V, the joint resists thermal cycling and mechanical stress without the degradation seen in unsoldered crimp barrels during long service intervals.

Questions about this item

What wire gauges fit the 18 AWG red butt splice?

The connector accepts 22 AWG to 18 AWG wire and crimps onto the stripped conductor before heating.

How do I install the heat-shrink solder splice correctly?

Slide the sleeve on, twist wires together, apply heat until solder flows and tubing shrinks fully — skipping the solder step leaves a cold joint.

When should I replace a used splice?

Replace any splice showing cracked heat-shrink, corroded tin plating, or one that has seen temperatures above 230 °F or below -67 °F.
