Stew gave you the part, (see image) but not the instruction on how to connect the two pipes.
Insert the doughnut into the cast iron hub. Now take a file and bevel off the edge of the PVC pipe so there are no burs. Now take axle grease or Duel-Tite Lubricant and slaver the out side of the PVC and the inside of the doughnut.
If it's a little difficult to start trimming off a few ridges with a sharp knife's acceptable. Now you can take a Johnson Bar Or a heavy rod and proceed to lever the PVC in until it bottoms out in the hub. Good luck, Tom
