Description

SylWrap ‘No Pressure Kit‘ is designed for pipe repairs where flow CAN BE isolated on pipes made from steel, stainless steel, copper, malleable iron, GRP, ceramic, clay, concrete, rubber and most plastics.

Each kit contains Superfast Copper epoxy putty, which is chemically resistant and provides greater scope for versatile repairs to complex pipe shapes by smoothing sharp steps created by pipe joints and filling large cracks. Overwrapping the Superfast Copper with SylWrap provides a high strength, pressure-resistant long-term repair.

Kit Contains Superfast Copper Epoxy to

  • Fill cracks
  • Remove “step” when repairing leaking joints
  • Smoothing off pitted substrates
  • Increase pressure resistance
  • Improve longevity and chemical resistance of repair

For depressurised repairs on

  • Leaking joints
  • Pinhole leaks
  • Cracks

For Depressurised Leak Repairs

Contains Superfast Copper Epoxy
