Heat shrinkable sleeve for protection of pre-insulated pipe joints

SuperSeal™ is a high performance, heat shrinkable product intended for sealing of pre-insulated pipe joints.

SuperSeal™ provides superior barrier against moisture ingress while protecting the joints from the soil stresses associated with Pre-Insulated Pipelines. Specifically designed for bonding to polyethylene pipes and casings, SuperSeal™ offers low substrate pre-heat temperature thus making the installation of this product simple, forgiving, and most importantly, reliable.

Effective Long Term Sealing

  • A combination of cross-linked polyethylene backing with a layer of unique hot melt adhesive, results in a long term barrier impermeable to moisture
  • As part of an insulated pipe joint casing and sealing system, SuperSeal™ complies with the stringent requirements of the EN 489 standard

Proven Track Record

  • SuperSeal™ has been protecting joints of pre-insulated pipelines for over 25 years

Reliable and Consistent Performance

  • Low installation pre-heat temperature ensures uniform and consistent bond to the substrate
  • High performance backing provides superior mechanical strength required for high stress environments

Flexible Product Options Save Time and Money

  • Available in three configurations: pre-cut to specific pipe size, bulk rolls and tubes
  • Allows for lower inventories of pre-cut sleeves and just-in-time sleeve cutting, thus reducing cost
