For fittings where operating temperature is below 45°F (7°C), or where the pipe insulation is greater than 2" (50.8mm), two or more layers of the insulation inserts are required beneath the NO SWEAT™ cover surface.
Hot Systems
  • Tychem QC should be limited and kept below 200°F (93°C) by use of proper insulation thickness.
  • Tychem QC should be kept away from contact with, or exposure to, sources of direct or radiated heat.
  • For fittings where operating temperatures exceed 250°F (121°C), or where pipe insulation is greater than 2" (50.8mm), two or more layers of the insulation inserts are required beneath the NO SWEAT™ cover surface.
