Seachoice Red Heat Shrink Tubing with Adhesive Liner

Seachoice heat shrink tubing with adhesive liner (also called 3-to-1 heat shrink tubing with sealant) is made from marine grade, flexible polyolefin. It protects and seals wire splices, terminals and cable ends on boats, trailers, RVs and automotive wiring. When heated, the tubing shrinks tightly around the connection. The built-in adhesive liner melts and flows to form a complete environmental seal.

Key Features:

• 3:1 shrink ratio: Shrinks to a third of its original diameter for a tight, secure fit over irregular shapes and larger connectors.
• Adhesive liner: The internal sealant melts during installation to create a moisture-resistant seal around the connection.
• Marine grade polyolefin: Flexible, durable construction suited to harsh marine environments.
• Flame retardant: Adds an extra measure of safety for electrical applications.
• Wide temperature range: Rated for operating temperatures from -55°C to 110°C (-67°F to 230°F).

Once installed, the tubing helps prevent corrosion, adds insulation and improves abrasion resistance. This protects wiring from moisture, chemicals and mechanical wear. It is a practical choice for marine electronics, battery cabling, lighting circuits and general electrical repairs.
