Heat Shrink Tubing

3:1 Shrink Ratio Shrink Tube

• When heat is applied, waterproof shrink tubing will recover to a 1/3 of its original diameter.
• Its high recovery ratio makes it possible to repair most damaged cable jackets without removing connectors.
• Therefore, 3:1 shrink ratio tubing can be used in significantly more applications compared to 2:1 shrink ratio tubing.
• Additionally, 3:1 marine heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps.

Heat Activated Adhesive Lining

• This is a waterproof shrink tubing with the internal adhesive layer.
• When heat is applied, shrink tubing recovers and the internal adhesive layer melts.
• A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing.
• When cooled down, it forms a rigid seal. Heat activated glue strongly adheres to wires, terminals or any other surfaces.
• When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection waterproof.
• For best results we recommend using a heat gun.

Dual Wall Shrink Tubing

• Dual wall marine grade heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to stand up to wear and tear. This wire heat shrink tubing is flame retardant.
