Concentric Reducer or Eccentric Reducer.
A Concentric Reducer joins the tube sections on the same axis. They connect unequal size pipes that have
a common centerline and are used for TC transitions in vertical tubing.
An Eccentric Reducer, also called a Bell reducer, has two female (inside) threads of different sizes with centers
so designed that when they are joined, the two pieces of pipe are not in line with each other, but they can be installed
so as to provide optimum drainage of the line.
What is difference between eccentric and concentric reducer?
Concentric reducers reduce the pipe in the center. So, if you're looking at the reducer head-on,
you can see the smaller section is formed in the direct center of the larger side.
Eccentric reducers reduce the pipe to the side. ...
Eccentric reducers are used when the pipes have to maintain the same top or bottom level.
