240/350/400PCS Solder Seal Connector Kit AWG 26-10

240/350/400PCS Solder Seal Wire Connectors Kit AWG 26-10 gives you mixed color-coded connectors for projects that use several conductor sizes. Each connector combines a low-temperature solder ring, a heat-shrink sleeve, and adhesive seals for controlled-heat wire splicing.

Kit and Wire Size Guide

Color AWG Pack Quantity Solder Ring Shrink Ratio Application
White AWG 26-24 240, 350, or 400PCS mixed kit Low-temperature solder ring 2:1 Fine signal wiring
Red AWG 22-18 240, 350, or 400PCS mixed kit Low-temperature solder ring 2:1 Small accessory wiring
Blue AWG 16-14 240, 350, or 400PCS mixed kit Low-temperature solder ring 2:1 Automotive and marine wiring
Yellow AWG 12-10 240, 350, or 400PCS mixed kit Low-temperature solder ring 2:1 Higher-current accessories

Connector distribution varies by the selected 240, 350, or 400PCS variant. Select by conductor gauge, not insulation diameter.

❓How to Choose

Match the conductor gauge to the color-coded AWG range in the table. Choose the 240, 350, or 400PCS variant by project volume and expected connector usage. Do not choose by outer insulation thickness alone.

❓How to Use

  1. Strip both wire ends without cutting conductor strands.
  2. Select the connector that matches the conductor gauge and insert the wires so they overlap inside the solder ring.
  3. Heat evenly with a controlled heat gun until the solder flows and both adhesive rings seal.
  4. Allow the joint to cool before testing, pulling, or energizing it.

Do not use an open flame, and do not install a connector outside its stated AWG range.

❓Do solder seal connectors require crimping?

No. Correctly installed solder seal connectors use controlled heat to solder, shrink, and seal the joint.

❓How do I select the color by AWG?

Match the conductor gauge to the table above. Do not choose by the thickness of the outer insulation.

❓How do I heat the solder ring without damaging the sleeve?

Use moderate airflow, rotate the connector, and move the heat source continuously until the solder has flowed and the adhesive seals have contracted.
