  • Reliable motor splices with brass body and steel contacts
  • Safe pool wiring rated for 600 V maximum voltage
  • Durable power-cable seals using cross-linked polyolefin heat shrink
  • Adhesive-lined tubing resists moisture up to 221 °F
  • Fits conductors up to 0.26 in outer diameter

Ideal 46-405 Wire Connector Kit

The Ideal 46-405 Wire Connector Kit provides insulated splices for copper conductors up to 2 AWG. It is designed for electricians and technicians working on motor connections, pool wiring and power cable repairs. The kit uses cross-linked polyolefin tubing with an adhesive liner to create a watertight seal. It is rated for 600 V maximum voltage and a maximum operating temperature of 221 Degrees F.

Upgrade from tape or basic connectors

This kit replaces electrical tape and standard twist-on connectors that can loosen or allow moisture ingress over time. The heat-shrink method creates a permanent, sealed joint that resists vibration and corrosion in damp environments. The jump is worth it when a repair must withstand direct burial, pool chemicals or continuous mechanical stress on motor leads. It is not suited for aluminium conductors or cables larger than the stated maximum.

Straightforward heat-shrink installation

Installation requires a heat gun or torch to shrink the tubing until the adhesive liner flows and seals the connection. The tubing shrinks to fit a maximum cable OD of .26 in, so verify conductor insulation diameter before starting. Common issues include insufficient heat causing a loose seal or overheating that damages the brass splice body. Ensure the adhesive liner melts fully around the joint for reliable waterproofing.

Questions about this item

What is the maximum cable outer diameter that fits inside the 46-405 splice kit tubing?

The heat-shrink tubing accepts cables up to 0.26 in outer diameter before shrinking.

Which step is most often missed when installing the 46-405 connectors?

Applying heat evenly until the adhesive liner melts and seals the joint is the step installers skip.

At what temperature should the 46-405 splice kit be replaced?

Replace any kit exposed above 221 °F because the cross-linked polyolefin rating is exceeded.
