18 AWG Red Butt Splice Connectors

These Velvac 30130 connectors accept wires from 22 AWG to 18 AWG and come in a pack of 10. The red nylon insulation with heat-shrink tubing provides a sealed crimp joint for automotive and industrial wiring.

Heat-shrink insulation seals the joint

Each connector uses a brazed-seam copper barrel covered by polyolefin heat-shrink nylon that shrinks when heated. The tubing creates a moisture-resistant seal and adds strain relief without separate tape or tubing.

600 V and 221 °F operating limits

The connectors are UL listed and CSA certified for up to 600 volts and a maximum temperature of 221 degrees Fahrenheit. Builders working above those ratings or needing larger wire gauges must choose a different part.

Questions about this item

How often will the nylon heat-shrink insulation on these 18 AWG butt splices need replacement under normal automotive use?

The nylon with heat-shrink insulation is rated to 221 °F and 600 V, so it lasts the life of the splice unless physically damaged.

What is the first limit reached when these 10 brazed-barrel connectors carry continuous current at 600 V?

The 221 °F maximum operating temperature is the limiting factor before the copper barrel or insulation degrades.

How much heat does each 2.04 in red connector dissipate when crimped to 18 AWG wire and run all day?

Heat output depends on actual current load; the connector itself adds negligible resistance when properly crimped.
