I have a filter that has a 2inch inlet/outlet; but confused as to my pipe size - if I am using 50mm pipe size is that a match for the 2 inch inlet or I should be using 63mm and that would be an exact match?
 
Welcome to TFP.


a 2” (NB) tube has a 60.3mm od and is also known as 50mm N.B., but the metric equivalent is actually 63mm OD
