Wire Range Coverage

This kit supplies 100 heat-shrink butt connectors spanning 22 to 10 AWG, colour-coded red, blue and yellow for quick size identification. It suits automotive, marine, industrial and DIY electrical work where moisture-resistant splices are required.

Sealed Crimp Performance

Each connector uses a dual-wall tube with a 3:1 shrink ratio and internal hot-melt adhesive that seals out moisture and air after heating. The seamless copper core provides low-resistance current flow and resists pull-out once crimped and shrunk.

Compatibility Check

Verify that your wire gauges fall within the 22-10 AWG range and that you have a heat source such as a heat gun or lighter to activate the adhesive-lined tubing. Ensure your crimping tool can accommodate the barrel sizes supplied in the three colour groups.

Questions about this item

Will the adhesive-lined heat-shrink tubing on these connectors degrade and need replacement after long exposure to moisture?

The dual-wall tubing with hot-melt glue creates a permanent moisture seal; once properly shrunk it does not require scheduled replacement.

What wire gauge stops me from using the largest yellow connectors in a continuous high-current circuit?

Yellow connectors accept 12 and 10 AWG conductors; the copper barrel and crimp are the limiting factors for sustained current.

How hot do the crimped joints get when the kit runs at full load all day inside an engine bay?

Thick seamless copper barrels minimise resistance, so temperature rise stays low even during extended operation in hot environments.
