200-Piece 16-14 AWG Connector Kit

This kit supplies 200 blue heat-shrink butt connectors sized for 16 to 14 AWG wire. The tinned copper cores deliver strong crimps and high conductivity for reliable splices. They suit automotive, marine and general electrical wiring tasks where a waterproof seal is required. UL listing confirms the product meets recognised safety standards.

3:1 Shrink Ratio and Temperature Limits

Each connector uses a 3:1 polyolefin shrink tube lined with hot-melt adhesive to create a watertight bond. The tubing begins to shrink at 175 °F and the assembly is rated for continuous operation from -60 °F to 260 °F. A heat gun is needed to activate the adhesive and complete the seal; crimping alone will not waterproof the joint.

Verify Wire Gauge and Tooling Before Buying

Confirm that every conductor you plan to splice falls within the 16 to 14 AWG (1.5 to 2.5 mm²) range; thicker or thinner wires will not seal correctly. Ensure you have a suitable crimping tool for the tinned copper barrel and a heat gun capable of reaching the minimum shrink temperature. The connectors are single-use and cannot be reopened once heated.

Questions about this item

Should I pick the 200-piece pack or one of the larger kits such as 500 or 1000 pieces?

The 200-piece pack suits occasional repairs or a single vehicle job; larger 500-piece and 1000-piece kits are available for workshops or fleet maintenance.

What does the 16-14 AWG rating mean when I am splicing wires in my car?

It covers wires from 1.5 to 2.5 mm², typical for lighting, accessory and sensor circuits in automotive and marine wiring.

How does the 3:1 shrink ratio and 175 °F minimum shrink temperature affect the seal?

The tubing shrinks to one-third its original diameter and the hot-melt adhesive flows at 175 °F, creating a waterproof, corrosion-resistant joint rated from -60 °F to 260 °F.
