Removing Ty-seal from Cast Iron hub

[Newbie420]

Hi,

Is it possible to remove the broken piece and the rubber seal out of the hub? if so, what would be the best way?
End goal is to replace the broken cast iron piece with ABS

I would try a big flat blade screwdriver tapped in vertically at the interface of the hub and rubber donut. Then pry.

I think so too. Diablo makes a good blade for cast iron.

Are you suggesting cutting the hub off completely then couple it with a no-hub couplings (fernco)?

Or cutting just the rubber gasket? If so, how can I remove the section of the pipe inside the hub? I believe this is the gasket used https://www.anaco-husky.com/upl/dow...ubmittal-sheet-ty-seal-sv-gasket-ff6c5d1f.pdf

Thanks!

I guess both ways, if there isn't raised print on the pipe behind the bell, then cutting there works with the proper coupling. Check the OD of the cast, sometimes it's more of a copper size on the outside.
If removing the cast and donut from the hub, that involves some work. Normally I'm pulling a lead bend with a brass insert that I can cut and fold inward.

Sometimes you have to cut the hub grind down any lettering on the pipe and use a Mission coupling CI X Copper or XHCI x NO HUB

Or CI to Copper

Tip Jar for Terry or Saint Jude's or the Schreiners would be apricated

This is a bit of late update. I followed Terry's advice and it worked.
I left the rubber seal in there, and I used a 3" to 2" fitting to go over the hub. I was lucky that the hub fit perfectly to the 3" end of the fitting.
I took an identical hub to Ace hardware and fit check it to the fittings. Hopefully, this helps someone with similar problem.

Sorry to bring this thread back from the dead, but does anyone have any word on whether or not newbie420's solution is a good one? I am currently dealing with this exact same situation. Gut feeling seems to say that a reducing Fernco over the hub is not a good idea with broken pipe and an old donut in there.

That said, this would sure make my life one heckuva lot easier if this is an accepted method to deal with this. This will be an underground application.

Thanks all.

EDIT: I would of course be cutting the broken pipe flush with the opening of the donut with a sawzall if I went forward with this...

I think it looks ok best would be to cut hub off In my opinion and then as others mentioned grind off the bumps . Or better yet get rid of all that old stuff put new in . Kind of depends on how good is good enough I think its a relatively sound joint
