Fernco P44u-405 Cast Iron Hub Donut, 4 In.

The Fernco P44U-405 Cast Iron Hub Donut is a flexible compression ring designed to connect 4-inch service weight cast iron pipe to the plain end of 4-inch PVC Schedule 40 plastic pipe. This donut-shaped fitting creates a strong, lasting joint for sewer pipe and DWV (drain-waste-vent) connections, including sockets, hubs, bells and spigots.

The removable design means the donut can be taken out without damaging surrounding pipe, making repairs and inspections easier. As a lead-free, UV-resistant fitting rated for underground installation, this connector performs reliably when buried in below-grade applications and resists corrosion over time.
