Cool-Skin™LT Sleeve

Cool-Skin™LT sleeve is an ideal safety solution that has been designed to drastically reduce hot surface temperatures to a safe touch conditions.  This highly effective insulation sleeve offers excellent burn protection when installed around hot flexible metal hoses, large diameter pipes, valves and other high temperature process lines. 



Cool-Skin™ Technology

  • Worbo’s Cool-Skin™LT is manufactured from a flexible, clean, non-fibrous, closed cell and lightweight elastomeric material that does not contain fiberglass or release airborne particulates.
  • Well suited for use in a variety of environments from heavy industrial applications to clean-room and laboratory settings.
  • This user friendly product is equipped with a hook and loop self-gripping closure for ease of field installed (or removed for maintenance) without line disconnection.
  • Cool-Skin™LT Sleeve offers very good resistance to water absorption, UV radiation, ozone exposure, corrosion, noise and a wide variety of chemicals in general.
  • Cool-Skin™LT sleeve is supplied with a bright safety yellow protective neoprene coated jacket designed to alert personnel to potential danger.
  • Unlike traditional dated technologies that use glass as the insulating medium, Cool-Skin™ LT Sleeve is easily cut to length in the field using an ordinary pair of scissors without “end fray” or releasing irritable fiber particulates.
