Pacific Industrial 8232C 3/8" Dual-Wall Waterproof Heat Shrink Tubing 4-6 Piece Pack

The Pacific Industrial 8232C is a 3/8" dual-wall waterproof heat shrink tubing designed to provide a reliable, moisture-proof seal on wire splices, connections, and cable ends. Each package includes 4 to 6 pre-cut pieces, making it convenient for automotive, marine, RV, and powersports electrical repairs.

Constructed from rigid polyolefin dual-wall material, this tubing features an outer wall that shrinks tightly around the connection while the inner adhesive wall melts and flows into voids, creating a watertight, corrosion-resistant bond. The 3:1 shrink ratio ensures a secure fit over a wide range of wire gauges and connector sizes.

• 3/8" inside diameter before shrinking
