I'm slowly learning the lingo...such as 1-1/4" pex can have a true ID of 1.07", 1.054", or even 1.28".
So, when it comes to the fittings...do you need to purchase specific to the brand of Pipe?
I was leaning toward expansion fittings so I'd have no restriction at the fitting. Worth the effort?
Regards, Scotty
