TTP HARD’s adhesive lined heat shrink tubing provides a fast, professional way to seal, insulate, and protect electrical joints and cables. The dual-wall design combines a tough, flame-retardant polyolefin outer layer with a hot-melt adhesive lining that melts and bonds as it shrinks, forming a durable, waterproof seal. Ideal for automotive wiring, plant machinery, marine, and DIY electrical repairs, it offers flexibility, strength, and corrosion resistance in one simple solution. Supplied in convenient 1.2m lengths, it’s easy to cut to size for any job. Whether you’re repairing connectors, sealing exposed joints, or adding strain relief, TTP HARD heat shrink tubing delivers a clean, long-lasting finish trusted by professionals across the UK.

TTP HARD’s adhesive lined heat shrink tubing provides dependable insulation, sealing, and strain relief for electrical and mechanical connections.
Designed for professional use across automotive, plant, marine, and DIY applications, this dual-wall tubing delivers a clean, waterproof finish that lasts.
The outer layer of flame-retardant polyolefin shrinks tightly when heated, while the inner hot-melt adhesive melts and flows to seal against water, oil, and corrosion — forming a strong, permanent bond.
What Is Adhesive Lined Heat Shrink Tubing?
Also known as glue lined heat shrink or dual-wall heat shrink, this tubing combines two protective layers:
-
Outer sleeve: Flame-retardant polyolefin for insulation and abrasion resistance.
-
Inner liner: Thermoplastic adhesive that melts and encapsulates the cable or connector when heated.
As the tubing shrinks, the adhesive flows and bonds to the surface, creating a waterproof, vibration-resistant seal ideal for cable repairs, connectors, and splices.
See It in Action
Watch how the hot-melt adhesive flows around the cable joint, creating a tough, waterproof seal that locks out moisture and corrosion.
Perfect for clean, long-lasting electrical connections in automotive and outdoor environments.

Frequently Asked Questions
Q: What’s the difference between single-wall and adhesive-lined heat shrink?
A: Single-wall provides insulation only. Adhesive-lined versions include a hot-melt liner that seals against water and corrosion.
Q: Can it be used outdoors or in marine applications?
A: Yes — once shrunk, the adhesive forms a watertight seal ideal for damp or saltwater environments.
Q: What temperature is needed to shrink it?
A: Start heating at around 95°C, and continue up to approximately 120°C for full recovery.
Q: Is it suitable for automotive wiring?
A: Absolutely. It’s ideal for protecting and sealing electrical joints in vehicles, machinery, and trailers.
Q: Can I buy small quantities or custom cut lengths?
A: Yes — our tubing is supplied in 1.2m lengths.
