Reducers<br />
Eccentric and concentric reducers, illustrated in Fig-<br />
ure 2-9, are used <strong>to</strong> reduce a line <strong>to</strong> a smaller size. Very<br />
few eccentric reducers are used in piping systems,<br />
therefore it is not difficult <strong>to</strong> tell which is which. The con-<br />
centric reducer has an inlet and outlet that are on a cen-<br />
ter line.<br />
The eccentric reducer has an off-center outlet, and is<br />
flat on one side. The eccentric reducer fits flush against<br />
a wall, ceiling, or floor <strong>to</strong> give greater pipe support <strong>to</strong> the<br />
line.<br />
