Fernco or Mission coupling, you need the outside dia. and inside dia. of both pipes. Most big box stores carry them, but if not go to a plumbing supply house. Keep in mind that the root prob. will come back in any Orangeburg that remains. Luck.

Just wanted to share a little knowledge with the group.
The best way to connect PVC to Orangeburg or clay sewer tile pipe is an epoxy putty found in the plumbing dept.
You squish this stuff like playdoh into the female end of the orangeburg and push your PVC into that and it hardens up in about 15 minutes.
I also found out how to reseal orangeburg to orangeburg.
I met an old man in the plumbing dept at Home Depot. He is at least as old as my house. He told me that the best way to reseal orangeburg joints is to pour a bag of quickcrete on top and just bury it. Shocked
Said that roots would have a devil of a time getting through 3 inches of concrete.
Needless to say, we are finished with this project and are now getting ready to sit on our butts for the rest of the weekend.

Both of these items probably work great; but neither are an "approved" application.

"but neither are an "approved" application"

Neither is putting a "brick, big rock or block" under a sewer pipe....:)

Well, since this old guy was a retired plumber, I'll take his word over other opinions.
He told me that he has replaced more orangeburg than you could shake a stick at.
He also told me that city inspectors approved of the quickcrete method.
All I really care about is that my plumbing is clean and the roots shouldn't ever be a problem again.

I'm having plumbing issues and have reason to believe that the line from my house to the street is made of Orangeburg (the downspouts dropped into Orangeburg pipe which then fed into cast iron under the house). Other than diggin up my recently finished landscaping and possibly the entire front yard, are there other methods to "replace" the pipe. I believe there is some method in which they run a tube inside the pipe and then expand it. Is this expensive and a permanent solution?

Four months ago I hand-snaked the line out 25 feet, which seemed to remove the clog. However, it back up again, so I power-snaked it (90ft) out to the city's main line. I will be only running clean water through the pipes, and if it backs up again, I will know I have a serious problem. At that time, I will most likely have a camera run down the line before digging, etc.

I guess I am anticipating the worst and looking for possible solutions when the time comes.

Thanks in advance for any info.

This Old House from this season has an episode where they relined the existing sewer pipe. It's program #2605.

I ran into an issue with my septic system where the T had broken off inside of the Septic tank and the sewage had backed up. After digging to the septic tank and uncovering the nearby distribution Box I found that the Orangeburg pipe coming from the tank to the box was badly clogged by hard stuff and the Box was rusting away but the line out of the box to the Dry well was OK I also found the pipe that had been disconnected years ago to another dry well and I reconnected that one as well. The biggest problem I had was finding something to use as a coupling to connect the Orangeburg to the PVC. What I finally found was that there is a Fernco fitting used for drains like gutter systems use that worked very well. The Fernco Part number was 1070-44. I had to modify this piece by cutting of a lip on the inner part where it was to connect to the Orangeburg but then it fit perfectly. After the connections were made and the new pipe and T installed I concreted over the Ferco fittings which should insure at least 50 years of life out of them and is accepted for sewer system repairs nationwide

Found pressed into an orangeburg and p.v.c glued into has anyone seen this before or know what this fitting is called for future connections.

How about a heavy duty rubber boot w/ clamps to connect pvc to orangeburg pipe???
