reducer

A plumber installs a reducer to connect two different-sized pipes.

Definition
  1. Noun:
    • A pipefitting that joins two pipes of different diameters: A mechanical component used to connect two pipes, allowing for a change in the flow diameter from a larger pipe to a smaller one, or vice versa.
    • A substance capable of bringing about the reduction of another substance as it itself is oxidized: In chemistry, a reagent that donates electrons or hydrogen atoms to another substance, thereby reducing it, while the reducer itself is oxidized. This process is used in applications like photography to lessen the density of a negative.
Examples of Usage
  • Noun:
    • The plumber installed a reducer to connect the wide main pipe to the narrower branch line.
    • In the darkroom, a chemical reducer was applied to the overexposed negative to lighten the dark areas.
