  • Certified to UL, CE, RoHS, SGS and ISO 9001 quality standards
  • Dual-wall heat-shrink tubing with hot-melt glue seals against air leakage

AIRIC 100-Piece Blue Heat Shrink Butt Connector Kit

This kit supplies 100 heat-shrink butt connectors in three colour-coded sizes for marine, automotive, industrial and hobby wiring. It covers wire gauges from 22 AWG up to 10 AWG across the assortment. The dual-wall tubing with inner hot-melt adhesive creates a moisture-resistant seal when heated. Connections are crimped then shrunk for a permanent, insulated joint.

Thermals noise and power draw

These are passive components that generate no heat, emit no noise and draw no power during operation. The copper cores conduct current with minimal voltage drop while the adhesive-lined shrink tubing insulates against environmental moisture. No external power source or cooling is required for the connectors themselves.

Build quality and daily use implications

The connectors carry UL, CE, RoHS, SGS and ISO 9001-2005 certifications from the manufacturer. Seamless thick-wall copper tubes resist pull-out and corrosion in vibration-prone environments. The 3:1 shrink ratio accommodates a wide range of insulation diameters. Colour coding — red for 22-16 AWG, blue for 16-14 AWG, yellow for 12-10 AWG — speeds identification on the job. Not suited for applications requiring soldered or compression-only joints without heat activation.

Questions about this item

How do I install the blue butt connectors on 14 gauge wire and what step is often missed?

Strip the insulation, insert the wire fully into the copper barrel, crimp with a ratchet tool, then apply heat evenly until the dual-wall tubing shrinks and the inner glue flows — skipping the glue melt leaves the seal incomplete

What maintenance or replacement will the heat-shrink butt connectors need after installation?

The connectors are sealed with hot-melt adhesive inside a 3:1 shrink tube, so no periodic maintenance is required; replace only if a visual inspection shows physical damage or corrosion on the copper barrel

What limit appears first when the blue connectors carry continuous current on 14 gauge wire?

The 14 gauge conductor reaches its ampacity limit before the copper barrel or dual-wall insulation does, so the wire gauge dictates the sustained-current ceiling
