I need to connect to an existing vent stack that is 2-3/8″ in diameter, that I need to connect a pvc vent stack to. Problem is, there are to my knowledge, no rubber couplings that have a 2-3/8″ Inside Diameter.
I’m thinking it would not be a good idea long-term to stretch a 2″ coupling to 2-3/8″, but would a 2-1/2″ coupling take up that 1/8″ of slack? Open to other suggestions…
Thanks, PJ

if that is the OD (Outside Diameter) mearsurement it is a 2" pipe...
pipe is read and called by the ID... (Inside Diameter)...
if the stack is a galvinized or iron pipe - whatever sizw you are trying to hook up by 2" iron is what you are looking for...

It is actually even a little more complicated. For 1" ANSI Schedule 40 steel pipe the actual internal dimension is specified as 1.05 inch while the external diameter is 1.32". For Schedule 80 steel pipe, the external diameter remains the same while the extra wall thickness reduces the internal diameter to 0.96". There are even heavier wall thicknesses of steel pipe that reduce the internal diameter even further. The Engineer's Tool Box has tables that give standard dimensions for ANSI Schedule 40 and Schedule 80 steel pipe at:http://www.engineeringtoolbox.com/ansi-steel-pipes-d_305.html

I know this...
and then we get into SCH120.....
but for the OP and his residence figuring in SCH40 should do just fine.........

To make it even more confusing, 2" iron pipe is larger than 2" ID (or at least that's true with smaller pipes). The inch designation refers to the mythical pipe produced back around 1890, and the stuff used since maybe 1935 has a thinner wall and hence larger ID (to maintain the same OD, since that's where the threads are).
Similarly, plastic pipe comes in several different wall thicknesses, with corresponding differences in ID.

But to be even more confusing while pipe is designated by ID, tubing is designated by OD.Thus compression fittings for used with 5/8" copper tubbing is perfect fit for 1/2" copper pipe..

wait till they make metric pipe..lolSpheramid Enterprises Architectural Woodworks

Years ago I heard something interesting about metric standards.They said that things like screws using metric screws where completely different from ASE standards.But other items, one mentioned was oil field pipe, was given metric numbers, but in fact was still the US standard dimenensions..
