Why We Love It

Self-seals for efficient fixing.
Extra durable with Tiger Technology.
Versatile for various repair needs.

Main Highlights

🐯💧 Grippy, Not Sticky – Don’t worry if it doesn’t feel sticky! Tiger Tape activates when stretched and wrapped onto itself. The layers self fuse into a durable, waterproof, and airtight seal — no glue, no residue, no mess, so easy to work with.
🐯🛠 Emergency Seals for Pipes, Cables & More – Perfect for insulating wires, sealing pipe drips, or reinforcing tool handles. Ideal for plumbers, electricians, campers, and DIYers. Not a pressure-rated fix — use for low-stress or emergency sealing.
🐯☀️ Made for Harsh Conditions – Durable rubber withstands water, UV, heat, and frost. Whether indoors, outdoors, or on the move, Tiger Tape stays strong in tough environments.
🐯❄️ Freeze-Prep Friendly – Use Tiger Tape to wrap exposed pipes in cold snaps. Reinforces insulation and helps prevent bursts — a smart extra layer of winter protection.
🐯🚫 Not for High-Pressure Hoses – Avoid using on burst garden hoses or expanding/fabric types. This tape works by fusing to itself, not the surface, so it's best for solid materials like PVC or rubber — and only when dry, clean, and tension-wrapped. For pressurised repairs, use a mechanical clamp or replace the part.
🐯🔧 Multi-Use Must-Have – More than leak repairs: wrap tool handles for extra grip, insulate electrical wires and connectors, tidy automotive cables, or seal gear in outdoor and marine settings. Keep a roll in your toolbox, van, or camping kit — you’ll always find a use for it.
🐯💧 How to use: Simply stretch tight the tape around the affected area and wrap, overlapping it to form a watertight bond. No tools needed! Stretching improves adhesion. With Tiger Technology, it's hassle-free for both pros and beginners—no DIY expertise required!
🐯📏 5 Metres of Heavy-Duty Tape – More than most brands. Wrap multiple repairs or reinforce longer areas — great to keep in the van, garage or emergency kit.
