Cut out the old lead pipe all the way back to the brass caulking ferrule. This should bring you up to the lead and oakum joint in the cast iron hub. You will now have to remove the brass ferrule and lead joint. To remove a poured lead and oakum joint take a 3/8" drill bit and drill a few holes down past the lead and into the oakum.. Push a screwdriver under the lead ring and lever it up. Once it's free you can began to peel the lead ring out. Now pick out the oakum and you can pull the joint apart.
OK! Now you are left with a open hub. A Neoprene Gasket,)(see image) will then be inserted into the hub and the PVC into that. Let me show you how.
Duel Tite connections go like this. You first insert the gasket into the hub of a cast iron fitting. Next you paint the inside of the gasket with Duel Tite Lubricant and file a bevel on the end of the PVC pipe so it will slip in and start to seat. Now paint the pipe and insert it into the gasket making sure that it goes in straight and not cocked. If there's a problem getting it started it's acceptable to take a knife and trim the first few ridges off the front of the gasket. Now simply place a Johson Bar, (And I'll bet you thought a Johnson Bar only lived in your trousers) on the end of the PVC and push it in until it seats. Good luck, Tom

What part of this did you not understand? OK! Now you are left with a open hub. A Neoprene Gasket,)(see image) will then be inserted into the hub and the PVC into that. Let me show you how.
