How to Use the Self-Fusing Silicone Tape

  1. 01

    Cut the tape

    Clean the application area and cut the tape to the required length.

  2. 02

    Peel the protective film

    Taking care to keep the tape clean and dry, peel back a small section of the protective film.

  3. 03

    Overlap onto the area

    Overlap the tape onto the application area.

  4. 04

    Stretch and wrap

    While removing the protective film, stretch the tape and wrap it around the application area.

  5. 05

    Fuses into place

    After application, the tape's self-fusing force locks it firmly onto the area.

*Please avoid repositioning or reusing tape once it has been applied.

Applications

Emergency Pipe & Hose Repair

Simply wrap around the leak point for instant fusion. No tools required for immediate emergency response.

Valve & Fitting Leak Sealing

High elasticity conforms tightly to curved and uneven surfaces. Handles complex-shaped areas with ease.

Preventive Maintenance

Low-cost and easy to keep on hand. Wrap preventively around areas showing signs of deterioration to prevent leaks.

Which Leaks and Locations It Works For

Because the Leak Stopper uses no adhesive and instead fuses to itself through silicone self-bonding, it conforms to oily or wet surfaces, uneven surfaces, and curves. Use it on pinhole air leaks in factory air piping and hoses, emergency repairs of water and hot-water lines, weeping around valves and fittings, and cable insulation or waterproofing - even in emergencies where no power or tools are available.

Leaks It Handles

Emergency repair of compressed-air leaks, water leaks and weeping, tiny pinhole leaks, and leaks from fittings or threaded joints. Withstands 1 MPa after application (proven at 1.5 MPa water pressure).

Where You Can Use It

Pipes, hoses, valves, fittings, electrical cables, and more. With -60 to 260C heat resistance and UV/ozone resistance, it works outdoors, on hot sections, and in humid or underwater environments.

vs. Ordinary Tape

Unlike vinyl tape that sticks with adhesive, the tape itself fuses into one body. It leaves no sticky residue over time and, because it is stretched into place, wraps with no gaps.
