Product documents: Sylmasta SylWrap Universal Pipe Repair Kit Technical Data Sheet
What leaking-pipe jobs is the Sylmasta SylWrap Universal Pipe Repair Kit built for?
Sylmasta SylWrap Universal Pipe Repair Kit permanently repairs leaking pipes even when pressure cannot be turned off. Typical work includes water and wastewater supply and treatment leaks, petrochemical gas, oil, and water lines, quarry wash-plant pipework, power-station cooling and ash lines, steelworks steam and slurry pipes, hospitality heating and air-conditioning lines, marine fuel, water, and waste pipes, and domestic water or rubber hose leaks. Repairs can be completed in under 30 minutes on steel, copper, plastics, and other plant substrates.
How do I use Sylmasta SylWrap Universal Pipe Repair Kit on a live leak versus a leak with pressure off?
If pressure cannot be turned off, stretch Wrap & Seal to three times its length and wrap it over the leak so it fuses into a solid rubber band that holds pressure. If pressure can be turned off, knead Superfast Epoxy Putty to a uniform colour and push it into holes and cracks; it hardens in 5 to 10 minutes. In both cases, wet SylWrap HD to activate the resin, wrap and smooth it over the seal, and allow a 2 to 5 minute work window with a functional cure in 30 to 45 minutes. Wear plastic gloves and follow the Safety Data Sheets.
When should I choose the SylWrap Universal Pipe Repair Kit 150mm x 10m (SYL-633-UP)?
Choose Sylmasta SylWrap Universal Pipe Repair Kit (SYL-633-UP) when you need a 150mm x 10m SylWrap HD bandage plus SylPad for pipes of approximately 150-300mm outside diameter. The shorter 150mm x 5m sister (SYL-616-UP) covers 100-150mm OD without SylPad. The 200mm x 20m kit (SYL-866-UP) steps up for 300-600mm OD. Confirm OD against the Universal Kit TDS size table before specifying.
Is Sylmasta SylWrap Universal Pipe Repair Kit approved for drinking-water pipes?
Yes. The SylWrap Universal Pipe Repair Kit has WRAS approval, so it is listed as suitable for pipes and fittings carrying drinking water. That supports potable-line leak repairs where a WRAS-listed material is required. Always follow site hygiene rules and confirm the finished repair meets the local water-system specification before returning the line to service.
What pressure and temperature can a completed SylWrap Universal Kit repair handle?
With putty and SylWrap HD, maximum pressure resistance is 30 bar / 435 psi depending on the leak. For a live leak using one Wrap & Seal, the TDS lists 150mm: 8 bar / 225mm: 5 bar / 300mm: 4 bar. This kit includes SylPad, which is used with Wrap & Seal to concentrate tape pressure over the leak and multiply pressure resistance by up to three times. Maximum service temperature is 200°C / 390°F.
What is inside the 150mm x 10m Universal Kit, and which pipe materials can it repair?
The 150mm x 10m Universal Kit (SYL-633-UP) contains Superfast Epoxy Putty, 50mm x 4m Wrap & Seal Pipe Burst Tape, a 150mm x 10.0m SylWrap HD Pipe Repair Bandage, and a SylPad Pressure Resistance Multiplier.
