Description

Heat Shrink Solder Sleeve Crimpless Butt Connector – 12-10 AWG Yellow, 6mm

Overview

This heat shrink solder sleeve connector combines simplicity with reliability for professional wire termination. Designed for 12-10 AWG wire (2.8mm nominal), the 6mm connector size accommodates standard electrical and automotive wiring applications. Each unit features a pre-loaded solder sleeve inside a color-coded yellow heat shrink tube—eliminating the need for separate crimping tools or manual solder application. Your customers can complete solid, corrosion-resistant connections in seconds using only a heat source. Stock this 100-piece pack to serve technicians working in automotive, industrial controls, marine, and general electrical maintenance. Pair this with comprehensive terminal assortments or larger heat shrink connector sets to build a complete connector solution for your shop.

Key Features

  • Pre-loaded solder sleeve – Solder preform integrated inside the connector; no separate solder required
  • Color-coded yellow – Instant visual identification for 12-10 AWG wire gauge
  • Crimpless design – No crimping tool needed; solder reflow bonds wires permanently
  • Heat shrink insulation – Integrated tube shrinks to seal the joint and provide weatherproof protection
  • Butt connector configuration – Joins two wires end-to-end for clean terminations
  • 100-piece bulk pack – Economical quantity for resale or high-volume shop use

Business Advantages for Resellers

  • High-margin consumable – Customers repeat-purchase connectors regularly; strong turnover potential
  • Universal appeal – Suitable for automotive technicians, electricians, industrial maintenance, and DIY professionals
  • Low hold cost – Compact packaging and long shelf life mean minimal inventory risk
  • Minimal skill barrier – Heat-only installation removes tool investment barriers for end-users, driving adoption
  • Complete solution – Bundle with ratchet crimping tools or larger connector sets to increase ticket size
