Qualifications for use

Cold Systems

For fittings where operating temperature is below 45°F (7°C), or where the pipe insulation is greater than 1.5" (38mm), two or more layers of the insulation inserts are required beneath the NOSWEAT™ valve 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 1.5" (38mm), two or more layers of the insulation inserts are required beneath the NOSWEAT™ valve cover surface.

Sizing Parameters

a = Diameter of the insulated pipe
b = Length of valve. Allow for a 2" overlap.

Example: valve 4" long + 2" = 6" long end cap valve wrap

When ordering, use the Valve Wrap Chart for Side a, then choose desired length from the Valve Wrap Length Chart.
Example: Pipe diameter 3/4" x 1" thick insulation x 6" long use wrap #2.
