Actual Size 4.94" OD x 3.5 ID. Beginning of the drain is PVC, then to a 2" gavinized pipe (which rotted thru and is leaking) that leads into a cast iron hub which at that loc. Joints between the cast iron pipe Hub and the plastic spigot should be made using mechanical compression joint. Proflex Specialty Couplings. Elastomeric PVC (Polyvinyl Chloride) Maximum Working Pressure. Hello! Just wondering if anyone has a idea on what size donut would work to connect 2in pvc to the hub in this cast iron main stack. Fernco 4"Clay/Cast Iron x 3" PVC/ABS Compression Donut. is sealed with a lead packing. Made of tough elastomeric polyvinyl chloride (PVC), the flexible couplings are strong, resilient and unaffected by soil conditions. How to connect PVC to cast iron hub Experience a leak in the drain from sink to a soil hub. Designed for resistance to heavy earth loads and shear forces, and provides improved pipe alignment. This FERNCO straight flexible coupling is ideal for cast iron, plastic, copper, steel, or lead to cast iron, plastic, copper, steel, or lead pipe. And since most cast iron systems are underground, getting to the pipe or a usable piece of pipe might involve tunneling. At this point in the game, most cast iron is so bad that finding a viable piece to connect the PVC pipe is almost impossible. A "Fernco Donut " is recommended. 46.
