Adhesive Lined Heat Shrink Tubing 12mm (10 Pack) | Black, Waterproof & Sealed

This is a professional-grade, adhesive-lined heat shrink tubing designed to create durable, waterproof, and environmentally sealed connections. Each pack contains ten 300mm lengths of 12mm black polyolefin tubing. When heated, the tubing shrinks to 1/3 of its diameter, and the internal meltable glue activates to form a secure, airtight, and watertight seal around wires, cables, or splices.

Key Features & Benefits:

• Waterproof & Environmental Seal: The internal heat-activated adhesive liner melts and flows during shrinking, creating a permanent, flexible seal that protects connections from moisture, dust, corrosion, and vibration. Ideal for marine, automotive, outdoor, and underground applications.

• High 3:1 Shrink Ratio: The 12mm tubing shrinks down to approximately 4mm, accommodating a wide range of wire bundle diameters and providing a tight, strain-relieved fit.

• Durable & Protective: The polyolefin outer sleeve offers excellent abrasion resistance, electrical insulation, and UV stability. The sealed connection provides mechanical strength and strain relief.

• Professional Results: Essential for creating reliable, long-lasting seals on battery terminals, trailer wiring, outdoor lighting, marine electronics, and any connection exposed to harsh conditions.

• Convenient Pre-Cut Lengths: Supplied as ten ready-to-use 300mm (approx. 12-inch) tubes, perfect for multiple projects or longer cable runs.
