Sylmasta Wrap & Seal Pipe Burst Tape 25mm x 2m
Sylmasta Wrap & Seal Pipe Burst Tape is a self-amalgamating waterproof repair tape in a 25mm x 2m roll for sealing live leaks on smaller-diameter steel, copper, iron, plastics, and other pipe materials when pressure cannot be turned off. The high-stiffness 1mm tape stretches to three times its length so each wrap applies firm pressure over the leak until the layers fuse into a solid rubber band.
- WRAS-listed approval supports drinking-water pipe and fitting repairs.
- Repairs that need one Wrap & Seal can often be completed in under 15 minutes.
- Fused tape will not unwrap and can be removed later with a sharp blade if required.

Key Features
- Compact 25mm x 2m roll seals live leaks on smaller-diameter pipe without turning pressure off.
- High-stiffness 1mm tape stretches to three times its length so each wrap applies maximum pressure over the leak.
- Layers fuse into a solid rubber band that will not unwrap once bonded to the pipe and to itself.
- WRAS-listed approval supports drinking-water pipe and fitting repairs on potable systems.
- Tapered profile helps stop fluid tracking under the tape and maximizes surface contact with the pipe.
- Central white guideline aids the recommended 50% overlap for consistent wrap coverage.
- Repairs can be reinforced by overwrapping with SylWrap Pipe Repair Bandage for a rock-hard protective shell.

Frequently Asked Questions
What live-leak jobs is Sylmasta Wrap & Seal Pipe Burst Tape built for?
Sylmasta Wrap & Seal Pipe Burst Tape is a self-amalgamating waterproof repair tape for sealing live leaks on pipes of many types and diameters when pressure cannot be turned off. Typical work includes hot and cold water lines, chemical service pipe, and emergency wraps on steel, copper, malleable iron, GRP, ceramic, clay, most plastics, concrete, and rubber. Repairs can later be reinforced by overwrapping with SylWrap Pipe Repair Bandage.
How does Sylmasta Wrap & Seal Pipe Burst Tape seal a pressurized leak?
The tape is 1mm thick with a high-stiffness formulation and stretches by three times its length, so each wrap applies firm pressure over the leak. As it is wrapped tightly, Wrap & Seal bonds to the pipe surface and to itself, forming a solid rubber band that will not unwrap once fused. Multiple rolls applied on top of each other fuse the same way and can build pressure resistance up to 30 bar.
When should I choose the 25mm x 2m Wrap & Seal roll (PB-25x2HD)?
The 25mm x 2m roll (PB-25x2HD) is the compact Wrap & Seal size for smaller-diameter pipe and localized bursts. The TDS cites live pressure resistance of 12 bar on a 50mm pipe using PB-25x2HD when applied as directed. For longer wraps or wider coverage, step up to the 50mm x 4m or 50mm x 11m sister rolls.
Is Sylmasta Wrap & Seal Pipe Burst Tape approved for drinking-water pipe repairs?
Yes. Wrap & Seal carries WRAS Approval, so it is listed as safe to use on pipes and fittings carrying drinking water. That supports emergency and planned potable-line wraps where a WRAS-listed material is required. Always follow site hygiene rules and confirm the repair meets the local water-system specification before returning the line to service.
What temperature and fluid service can cured Wrap & Seal handle?
Sylmasta Wrap & Seal Pipe Burst Tape lists an operating temperature from −90°C to 200°C and is effective on pipes carrying hot and cold water and chemicals. Performance notes rate high-temperature, UV, moisture, and electrical insulation resistance as excellent, with good solvent and abrasion resistance. Confirm chemical compatibility for aggressive process fluids against the TDS before specifying a permanent wrap.
How do I apply Sylmasta Wrap & Seal Pipe Burst Tape and can I reinforce the wrap?
Stretch the tape firmly while wrapping, use the central white guideline to maintain approximately 50% overlap, and keep tension so layers fuse. Single-roll repairs can often be finished in under 15 minutes. If needed, the fused rubber band can be cut away with a sharp blade and leaves no residue. For a permanent shell, overwrap Wrap & Seal with SylWrap Pipe Repair Bandage to add a rock-hard, impact-resistant cover.
