TE Connectivity DuraSeal D-406-0001 Red Heat-Shrink Butt Splice (10 Pc)

TE Connectivity Raychem DuraSeal Red 22–18 AWG Heat-Shrink Butt Splice (10 Pc)

The DuraSeal D-406-0001 is a high-grade, environmentally sealed in-line crimp butt splice connector engineered for 22 to 18 AWG (0.38 mm² to 1.0 mm²) conductors. Designed for harsh marine, automotive, and industrial field splices, it combines a seamless tin-plated copper crimp barrel with a tough, radiation cross-linked nylon heat-shrink sleeve.

The interior of the heat-shrink sleeve is lined with a specialized hot-melt adhesive that melts and flows during heat application, encapsulating the wire entry points and creating a completely waterproof, strain-relieved, and gas-tight IP67 seal. Industry-standard red color coding ensures immediate recognition of conductor sizing during panel assembly or refit troubleshooting.

Key Features

• Dual-Action Environmental Seal: Crimp barrel secures mechanical wire attachment, while internal hot-melt adhesive flows to create a waterproof barrier against salt water, oil, and moisture.

• High-Purity Tin-Plated Copper Barrel: Lowers contact resistance and resists chemical oxidation and galvanically driven corrosion.

• Abrasion & Cut-Through Resistance: Tough nylon sleeve maintains structural flexibility without splitting or becoming brittle under severe vibration or extreme temperatures.

• Visual Termination Inspection: Translucent red insulation permits visual check of completed crimp alignment and adhesive seal ring formation.
