Sylmasta Wrap & Seal Pipe Burst Tape is a heavy-duty silicone repair solution designed to handle active pipe leaks under pressure — without shutting down the system. Engineered for rapid deployment in emergency situations, it provides a reliable, self-fusing seal that bonds instantly to itself, creating a durable and cohesive wrap that prevents further fluid escape. Unlike standard silicone tapes, Wrap & Seal is formulated with high stiffness and a tapered profile, enabling it to apply greater pressure per wrap and deliver a tighter, more secure seal even under live conditions.
Capable of withstanding internal pressures up to 175 psi (12 bar), it’s ideal for repairs on water mains, chemical lines, waste pipes, and industrial process systems. The tape’s 1mm thickness — the highest available — allows it to maintain pressure over leaks more effectively than thinner alternatives. Its WRAS approval ensures it’s safe for use on potable water lines, making it suitable for both domestic plumbing and commercial water infrastructure. When used as part of the Sylmasta Pipe Repair System and overwrapped with a SylWrap Bandage, Wrap & Seal can be part of a permanent pipe repair solution, restoring system integrity and minimizing downtime.
Whether you’re repairing a pinhole leak on a copper pipe, a split in a PVC waste line, or damage on a high-pressure hose, Sylmasta Wrap & Seal provides a fast, clean, and chemical-free solution that gets the job done without disassembly or interruption to service.

Frequently Asked Questions
Can this tape stop pressurized water leaks?
Yes. Wrap & Seal is designed to seal live leaks and can handle pressure up to 175 psi (12 Bar) when applied correctly.
Does it work on all pipe materials?
It adheres to most materials, including metal, PVC, rubber, and fiberglass. Surface prep is essential for rough or corroded pipes.
How long does the repair last?
Wrap & Seal provides a strong temporary seal. For permanent repairs, it should be overwrapped with SylWrap Bandage.
Can I use it in high-temperature environments?
Yes. The tape is rated for continuous temperatures up to 500°F (260°C) and resists extreme thermal cycling.
Is it reusable after opening?
No. Once the release film is removed and the tape starts to bond, it must be used immediately.
