PVC Duct Dimensions

GF Harvel PVC seamless round duct is extruded in 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 remains uniform. Produced in IPS diameters, GF Harvel PVC Duct piping has large internal flow areas that can easily be adapted to other common IPS PVC fittings, reducing fabrication and installation time. For space considerations in congested areas such as pipe chases, additional ID sizes are available in 7", 9" and 11" diameters. GF Harvel PVC Duct strictly conforms to the following dimensions:
