55 Piece Heat Shink Crimp and Solder Butt Connector Assortment Starter Kit
55 heat shrink crimp-and-solder butt connectors in three wire gauge sizes — red (22–18 AWG), blue (16–14 AWG), and yellow (12–10 AWG) — in a compact labeled kit. These butt connectors combine crimping and soldering in one step: the crimp holds the wire in place mechanically, and the solder slug melts during heat shrinking to flow through the wire strands, delivering a connection that's 80% stronger than standard PVC crimp terminals and fully sealed against moisture.
What's Included
- Red heat shrink crimp-solder butt connectors — 22–18 AWG, 20 pieces
- Blue heat shrink crimp-solder butt connectors — 16–14 AWG, 20 pieces
- Yellow heat shrink crimp-solder butt connectors — 12–10 AWG, 15 pieces
- 55 pieces total
Specifications
| Terminal type | Heat shrink crimp-and-solder butt connectors |
| Wire gauges | Red: 22–18 AWG / Blue: 16–14 AWG / Yellow: 12–10 AWG |
| Strength vs. PVC crimp | 80% stronger |
| Installation | Crimp wire, apply heat — solder flows automatically during shrink |
| Inspection window | Yes — visual confirmation that wire is seated correctly before crimping |
| Wire stop | Yes — prevents wire over-insertion |
| Seam construction | Brazed seams where applicable |
| Total pieces | 55 |
Best For
- Marine and RV electrical work — crimp-solder butt connectors are the industry standard for moisture-exposed wiring; the sealed heat shrink sleeve prevents the corrosion that eventually fails standard crimp splices in wet environments
- Automotive wiring repair and upfitting — splices on trailer wiring, aftermarket lighting, and accessory circuits are exposed to road vibration and weather; the crimp-plus-solder construction handles both
- Off-road and specialty vehicle builds — connections on builds that see vibration, water crossings, and high-heat environments benefit from the mechanical crimp and the sealed solder joint working together
- Any shop replacing standard crimp terminals — once you've used crimp-solder butt connectors, standard vinyl crimp terminals feel like a compromise on any connection that matters
How Crimp-and-Solder Butt Connectors Work
These butt connectors combine two connection methods in a single installation step:
- Strip and insert — strip the wire to the specified length and insert into the barrel. The inspection window lets you confirm the wire is fully seated before crimping. The wire stop prevents over-insertion.
- Crimp — crimp the barrel with the appropriate crimping tool. The crimp mechanically locks the wire in place and provides immediate tensile strength.
- Apply heat — use a heat gun on the connection. The heat shrink sleeve shrinks around the barrel, and the solder sleeve inside melts and flows into the wire strands, creating a gas-tight, soldered joint inside the already-crimped barrel.
The result: a connection with the mechanical holding strength of a crimp AND the conductivity and sealing properties of a solder joint — with the outer heat shrink providing a weatherproof barrier against moisture, corrosion, and abrasion. Questions? Contact us.
