Sylmasta Wrap & Seal Pipe Burst Tape 50mm x 11m
Sylmasta Wrap & Seal Pipe Burst Tape is a self-amalgamating waterproof repair tape in a 50mm x 11m roll for sealing live leaks on steel, copper, iron, plastics, concrete, and other pipe materials without shutting pressure 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.
- Tapered profile keeps fluid from tracking under the wrap to maximize pipe contact.
- Central white guideline aids the recommended 50% overlap for consistent coverage.

Key Features
- Long 50mm x 11m roll seals live leaks and supports extended or multi-wrap repairs without shutting 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 50mm x 11m Wrap & Seal roll (PB-50x11HD)?
The 50mm x 11m roll (PB-50x11HD) is the longest Wrap & Seal size in this family and suits extended wraps, larger leak areas, or stocking one roll for multiple plant repairs. Use the Sylmasta pressure tables or the wrap-seal repair calculator on sylwrap.com to confirm how many wraps and rolls a given pipe diameter and pressure need. Sister sizes 25mm x 2m and 50mm x 4m cover shorter or narrower jobs.
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.
