200-Piece Heat-Shrink Connector Kit

The INSCOOL kit supplies 200 UL-listed heat-shrink butt connectors in three colour-coded sizes. Tinned-copper barrels and adhesive-lined polyolefin tubing create waterproof splices for automotive, marine and general wiring repairs.

Sustained Environmental Performance

Adhesive-lined tubing shrinks and seals around each joint, maintaining a waterproof barrier that resists moisture, vibration and temperature cycling over time. The tinned-copper core retains conductivity and mechanical strength after repeated thermal expansion and contraction.

Pre-Order Compatibility Check

Verify that your wire gauges match the red, blue and yellow colour ranges and that you have a suitable crimping tool and heat source such as a hot-air gun. Confirm the 90 red, 90 blue and 20 yellow pieces cover the splice counts required for your project.

Questions about this item

How much heat do these connectors generate when used continuously in a wiring harness?

The connectors themselves are passive components and do not generate heat during operation; they simply join wires using tinned copper barrels and adhesive-lined polyolefin tubing.

What tools do I need to install the red, blue and yellow butt splices?

You need a wire stripper, a crimping tool suited to the three barrel sizes and a heat gun to shrink the tubing and activate the internal adhesive.

Can I mix these UL-listed connectors with older non-insulated terminals on the same circuit?

Yes, each splice is a standalone waterproof joint; the translucent heat-shrink tubing lets you verify the crimp visually before heating, so they integrate cleanly with legacy terminals.
