I have another thread where I'm remodeling my bathroom. I removed the old lead bend down to the cast iron hub. I'm trying to find the right sized donut to get a water tight seal but am having some problems.
I've taken measurements using a 1/32 ruler and to the best I can read the ID of the CI pipe is 5 4/32 (5.125). The ID of the pipe changes a little up or down but that seems to be the best measurement I can get. I've also taken some masking tape along the inside of the pipe to get a circumference. Assuming the pipe is mostly round I can figure out the average diameter. Circumference was 16.1875 which give me a diameter of 5.153.
Spoke to Fernco and my closest options are
44UX-305 - 5.05 OD and inside diameter made for a 3"pvc sch 40 pipe
412-305 - 5.147 OD and inside again made for 3 inch pvc
A426-305 - 5.21 OD again same for inside
My main problem is I cant find anyone who has any of these or will order a single one for me. Half the plumbing places I call tell me the service weight one will work. I have 3 service weight ones and they are very loose.
Any suggestions? The only one that comes up online is the 44UX-305 which I believe will be too small.
Also once I do find this part I need is there a correct way of installing? PVC into donut first then into cast iron hub or donut into CI hub then PVC into donut.
Do I use sealant anywhere? One picture I saw looked like there was black silicon where the pvc goes into the donut.
Thanks for any help
