How come McMaster says the ID of 3/4" CPVC is .742" then?

Hrm, thanks everyone.

Will 0.2in really make a big difference? I'm planning on having some pump-action design with a pipe sliding inside another pipe, and it's pretty complicated with a bunch of fittings and stuff. I'd have to buy all CPVC fittings for it to work, which would be more expensive than just buying regular PVC fittings. How much more expensive is CPVC than regular PVC?

Spudstuff, I live near LA, California.

Because that is sch40(or maybe 80) cpvc. What you want is CTS (copper tube size) CPVC. Most hardware stores carry the CTS CPVC. In fact every hardware store around me carries CPVC and it is all CTS http://www.harvel.com/piping-cts-dim.asp
