Reducer

Definition

A reducer is a pipe fitting which connects pipes of different sizes. It is also a tile trim unit used to reduce the radius of a bullnose or a cove to another radius or to a square.

Purpose

The purpose of a reducer is to join pipes of different diameters, ensuring a smooth transition and maintaining the integrity of the piping system. In tile work, a reducer creates a seamless transition between different tile profiles or sizes.

Examples of Use

• In plumbing, reducers connect larger main water lines to smaller branch lines.
• HVAC systems use reducers to transition between different duct sizes.
• Tile installers use reducers to finish edges and transitions in tiled surfaces, such as where a curved bullnose meets a square edge.

Related Terms

• Adapter: A fitting used to connect pipes of different types or sizes.
• Coupling: A fitting used to join two pipes of the same diameter.
• Bushing: A type of reducer that fits inside another fitting to reduce its size.

Notes

Reducers must be carefully selected to match the materials and sizes of the pipes or tiles they are connecting to ensure a proper fit and function.
