Wrap & Seal Pipe Repair Tape

Wrap & Seal Pipe Burst Tape

Wrap & Seal Pipe Burst Tape is a waterproof pipe repair tape made from self-amalgamating silicone which stretches by three times its length. As it is wrapped around pipework, it fuses to form a solid rubber band which seals live leaks. Wrap & Seal has WRAS approval and makes repairs to pipes of most materials and diameters.

The effectiveness of Wrap & Seal comes from being twice the thickness of other self-fusing waterproof repair tapes, its extra stretch and its unique tapered profile enabling more pressure to be applied per wrap.

Multiple tapes applied over each other will amalgamate in the same way, building a repair capable of withstanding up to 30 bar. Wrap & Seal is temperature resistant to 200°C and effective on steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber, and lead.

It 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.

No prior training is required before using Wrap & Seal. Simply follow the instructions provided. It can be used on pipes carrying hot water and chemicals.

Wrap & Seal is WRAS approved, meaning that it can be used safely with drinking water. The versatility of the product makes it suitable for wrapping other types of pipes, including car exhausts and hoses. It can also be used in electrical applications for insulation and repairing damaged cables.

Wrap & Seal Pipe Burst Tape Details

Wrap & Seal is easy to use and depending on the pipe size, pressure and number of tapes being used, repairs can be carried out in under 15 minutes.

The repair begins by anchoring the waterproof tape next to the leak area. Using the centre line as a guide, the tape is stretched to its maximum and wrapped around the pipe until it runs out. The unique tapered profile of Wrap & Seal stops water from tracking underneath the tape, maximising surface contact.

Each layer of tape increases the pressure resistance of the repair. To determine how many layers or tapes are required for a specific application, please use the Calculator tab to enter the repair details.

When repairing holes up to 20mm on pipe diameters in excess of 150mm, a SylPad Pressure Resistance Multiplier can be used in conjunction with Wrap & Seal.

SylPad better concentrates the elastic force of Wrap & Seal directly over the lean on larger diameter pipework, multiplying pressure resistance by up to three times.

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

Both Wrap & Seal and SylWrap Bandage 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.

Repair Calculator

Wrap & Seal Pipe Burst Tape Repair Calculator

The below Wrap & Seal Calculator can be used to determine the recommended number of Wrap & Seal Pipe Burst Tapes required to seal a live leak based on pipe diameter and pressure.

Enter the diameter of the pipe in millimetres, water pressure and the size of the hole requiring sealing in millimetres. The safety factor is a multiple to include a margin of safety. For example, if pipe pressure is 5 bar and you want a safety factor of two, the calculator will formulate a repair capable of withstanding 10 bar.

After entering your data, selecting the size of Wrap & Seal will determine how many of that specific tape are required for your repair. Repairs being made to pipes in excess of 150mm diameter with Wrap & Seal PB-50x4m or PB-50x11m should be made in conjunction with SylPad.

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, more than one Wrap & Seal can be used to stop the leak.
