Waterproof pipe repair tape made from self-fusing silicone which stretches by 300% its length to seal highly pressurised live leaks

SKU: PB Categories: ,


Wrap & Seal Pipe Burst Tape is a waterproof pipe repair tape made from self-fusing silicone which seals live leaks on pipes made from copper, PVC plastic, steel, malleable iron, and many other materials.

The tape stretches by three times its length and once applied, it fuses to form a solid rubber band which exerts maximum pressure over the hole or crack in the pipe. Using multiple tapes creates a repair which is pressure resistant up to 30bar and Wrap & Seal is temperature resistant up to 200°C.

Wrap & Seal is suitable for fixing leaks in applications ranging from small domestic plumbing problems through to large scale industrial pipe repairs. Because it is effective on live leaks, using Wrap & Seal avoids costly and disruptive shutdowns of systems.

The versatility of the product makes it suitable for wrapping car exhausts, hoses and other types of pipes. Wrap & Seal is WRAS approved, meaning that it can be used safely with drinking water.

Wrap & Seal can also be used as an electrical insulation tape. For more details, please go to the Electrical Repair Tab.

Wrap & Seal Pipe Burst Tape details – how to repair a leaking pipe with waterproof tape

Wrap & Seal is easy to use and depending on the size and pressure of the pipe, repairs can be carried out in under 15 minutes by simply following the instructions provided.

The repair begins by anchoring the waterproof tape next to the leak area. Using the centre line as a guide, you stretch the tape to its maximum and wrap it around the pipe until it runs out. The unique tapered profile of Wrap & Seal stops water from tracking underneath the tape, completely sealing the leak.

One Wrap & Seal Tape will typically hold 5bar pressure. Further pressure resistance can be built up by using additional tapes. If you are undertaking a high pressure repair, then please use the Repair Calculator tab to determine the number of tapes required for your repair.

Repairs made with Wrap & Seal should be reinforced by applying a SylWrap Pipe Repair Bandage over the Pipe Burst Tape. The Bandage offers a rock hard, impact resistant layer of protection which turns the repair permanent.

Both Wrap & Seal and SylWrap Bandages are available in the Universal Pipe Repair Kit which contains all the equipment needed for fixing live leaks in an emergency. For a kit that allows for multiple pipe repairs to be carried out, then please see the Contractor Case.

  • Repairs to non-plumbing pipes, such as car exhausts and hoses

Repair Calculator

The below calculator can be used to determine how many rolls of Wrap & Seal are required for a live leak repair up to a specified pressure resistance.

Enter water pressure, the diameter of the pipe in millimetres and the length of the crack. For pinhole leaks, leave the repair length field blank.

Once you have entered your data, selecting the size of a Wrap & Seal Tape will show you the quantity of that specific tape required to complete the repair.

Calculations serve as a guide to potential maximum pressure resistance only. Actual pressure resistance depends upon pipe material, condition, hole size, leak type and tension maintained during wrapping. If you are unsure, then more than one Wrap & Seal can be used to stop the leak.

Electrical Repair

Wrap & Seal can also be used in electrical applications for insulation and repairing damaged cables.

It offers a superior alternative to traditional adhesive electrical tapes because it fuses with itself and turns into a solid rubber band. This makes Wrap & Seal ideal for wrapping damaged wires, insulating terminal blocks, sealing around cable glands and wrapping and sealing junction blocks.

Only a minor stretch and one layer of Wrap & Seal are necessary when carrying out an electrical repair, meaning that one roll can be used for multiple repairs.

When sealing junction boxes against moisture, it is recommended that the cavity is first filled with Pack & Seal non-setting insulation putty first, before being wrapped with Wrap & Seal.


  • Wrapping damaged cables
  • Insulating terminal blocks
  • Sealing around cable glands
  • Wrapping & sealing junction boxes


  • Unlike other electrical tapes, Wrap & Seal self fuses
  • Only a small amount of tape is required per repair
  • Quick and easy to use
