copper fittings??

[mathew11]

Hi all,

I went to tradelink today and bought sme fittings.

My 1" copper elbows fit onto my pipe

How ever, my 1"-1/2" reducers dont fit. the 1/2" pipe fits in but the 1" side is the same size as my 1" pipe.

my 2" - 1" reducer is the same, 2" side is the same size as the 2" pipe so it wont fit, but the 1" side will fit the 1" pipe into it?

I am confused?????

Am I doing something wrong? or do i need to do something??

please help.
