Wrap & Seal Pipe Burst Tape
Wrap & Seal Pipe Burst Tape is a self-fusing silicone pipe repair tape which seals leaking pipes of all types and diameters even when water pressure cannot be turned off.
It is twice the thickness of other self-amalgamating waterproof tapes and stretches to 300% of its length, allowing for more pressure to be applied per wrap. Using multiple tapes can build a repair capable of holding up to 30bar.
Because Wrap & Seal is effective on live leaks, it avoids costly and disruptive shutdowns of systems. Wrap & Seal is temperature resistant to 200ºC, and is used on pipes carrying hot water and chemicals.
No prior training is required to use Wrap & Seal – simply follow the instructions supplied and apply the tape. It has WRAS Approval, meaning it is certified to British standards as safe to use on pipes carrying drinking water.
Wrap & Seal is used in applications ranging from small domestic plumbing problems to large scale industrial pipe repairs. It is effective on steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber, and lead.
To reinforce pipe repairs made with Wrap & Seal, Sylmasta recommend overwrapping the Tape with a SylWrap HD Pipe Repair Bandage. The Bandage offers a rock hard, impact resistant layer of protection.
SylWrap HD can either be purchased separately, or alongside Wrap & Seal as part of the Universal Pipe Repair Kit or the Pipe Repair Contractor Case, containing enough Tapes and Bandages to make up to six repairs.
How to fix a leaking pipe using Wrap & Seal Pipe Burst Tape
Fixing a leaking pipe with Wrap & Seal Pipe Burst Tape is straightforward. Depending on the diameter of the pipe, repairs can be made in less than 15 minutes.
The repair begins by anchoring the Wrap & Seal next to the leak area. Using the centre line of the Tape as a guide, you stretch it to its maximum and wrap tightly over the crack in the pipe until the Tape runs out.
As you apply Wrap & Seal, it will fuse into a solid rubber band, sealing the leak. The unique tapered profile of Wrap & Seal stops water from tracking underneath the tape.
Typically, one Tape will hold 5bar of pressure. Further Tapes applied on top of the initial repair will fuse to the previous layer, increasing pressure resistance. To determine how many Wrap & Seal are required to make a repair up to a certain pressure, please use the Repair Calculator.
Applications
- Domestic live leak repairs, including kitchen and bathroom pipes
- Industrial live leak repairs, including wastewater treatment works, quarry wash plants, dry risers, petrochemical plants, nuclear power plants, oil rigs, farms, hotels, and breweries
- Repairs to non-plumbing pipes, such as car exhausts and hoses

Wrap & Seal Pipe Burst Tape Case Studies
Wrap & Seal Repair Calculator
The Wrap & Seal Calculator determines how many Wrap & Seal Pipe Burst Tapes 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 or repair area. For pinhole leaks, leave the repair length blank.
After entering your data, selecting the size of Wrap & Seal will determine how many of that specific tape are required for your 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.
