CPVC Duct Dimensions

GF Harvel CPVC Duct is round, seamless extruded type, and is manufactured from 6" through 24" sizes to Iron Pipe Size (IPS) dimensions. GF Harvel’s unique precision extrusion technology produces duct with consistent proportional stability, assuring that the mechanical integrity of the duct pipe remains uniform. Produced in IPS diameters, GF Harvel CPVC Duct piping has large internal flow areas that can easily be adapted to other common IPS CPVC fittings, reducing fabrication and installation time.

GF Harvel CPVC Duct strictly conforms to the dimensions shown here:
