can someone confirm that they are 2.25"?

They are in MM's.

So if you see the pipe that is in question - and go to that install step they tell you the PN for the coupler to use.... and viola you have your coupler size.

^^

We just use it as a base here at work :D...

For this application, 1in=25mm should be accurate enough... .4 isn't so much when we're talking 50-75mm.

If a company is selling 75mm piping, they're not going to advertise it as 2.95", it'll be 3".

on my first pipe work I used 2.5" as I couldn't easily get 2.25". it is a tight fit but 2.5"can be used.
