What size are the correct fittings for 1 1/4" ABS pipe?

by Levi   Last Updated April 16, 2018 02:21 AM

I need to plumb into an existing ABS drain, labelled as "ABS/DWV 1 1/4" schedule 40 ", but for the life of me cant find any 1 1/4" fittings!!!

My suspicion is that the pipe is 1 1/4" ID, and I need to buy 1 1/2" OD fittings.

Before I trundle down to Home Depot, is anyone able to confirm my suspicion (or do I have the most useless, redundant piping ever?

Thanks!
