Cast iron compression fitting

Hello all,

Rob is the name and I need some help finding some parts. I'm doing a bathroom remodel and pulled the old 2 inch drain pipes from the cast iron fitting (sink drain pipe was badly scaled inside, shower drain pipe was loose in the fitting).

How do I install a new steel nipple into the cast iron pipe without packing oakhum and melting lead? No, I don't want to cut the cast pipes to use a hubless rubber band since this would require a larger section being replaced. The cast iron fitting is in good shape.

I've read in various threads about a rubber compression ring, but haven't seen one. The folks at a local plumbing supply hadn't heard of it, but they did have some oakhum and lead.

If you know a source for the needed parts, please post their contact information.

Thanks,
Rob

I could be wrong, but I don't think they make the donut in 2". They do have a "liquid lead" in a can that takes the place of hot lead. It is a plastic compound. Not sure who makes it.

They do make one, but making one, and finding one locally can be two different things. If no one ever uses one, then local companies have no need to stock them.

my 2 cents

hire a plumber for this one fitting

It looks like Ace Hardware sells the Fernco donut for 4" CI to 2" PVC which will also fit 2" steel. They have a variety of sizes at the same link.

Thanks for the replies and link.

I'll check out the local Ace hardware store for the ring.

I certainly understand why they won't stock it if no one buys it. The common practice is to cut out older sections and piece in with the hubless bands. Not that this is bad, but if in a visible space looks terrible. Of course, I'm not doing the typical hot mop with the new shower either.

If I can't get the ring, I'll look for the liquid lead stuff. I was thinking that if I couldn't find the rubber ring that I would try packing oakhum and using Bondo to seal it.

Oh boy.... Don't forget the duct tape on top of the Bondo!

I think the liquid lead is Otey or Hercules
