 There's always a possibility of that 

Something from a few years ago is trying to come back to me.
I bought some parts from Rona, and some from Vancouver Irrigation.
I'd swear the skid40 from Rona had a smaller I.D. than the skid80 stuff from VI.
Didn't make sense to me at the time as 1" is 1". I realize they both accept the same pipe size.
I'm thinking it was a valve comparison. May have been between a ball and true union ball. Can't remember.
