Where my 4" cast iron sewer line exits the house there is a 4" combination

I know I can get a 4"x4" PVC donut gasket and then put in a 4" cleanout
adapter.

However, I prefer to use metal parts if at all possible, brass or cast. *I
went to Charlotte Pipe web site and tried to see if I can find the right
parts but I do not see a part list. *I think I need some sort of a
adapter...for a 4" SV CI hub, that has a threaded ring on the inside for a

install it I would need to either epoxy it to the existing CI hub, or
someone who is skilled to use oakum and pour a lead joint, then I can insert
a threaded metal plug. *Does anyone have an online source where I can see
the parts with pictures?

Also I did find a 4" brass plug. *It's over $120.00. *Is this highway

Thanks,

SS (304) will be less but oyu might have to do the reducing bushing &
recessed hex plug dance.

a cast iron cleanout ferrule will be relatively cheap by comparison

I'd consider PVC
