A pipework reducing bush, commonly known as a reducing bushing, is a type of pipe fitting used to connect two pipes of different diameters. It is a cylindrical component with male threads on one side and female threads on the other. The male threads are of a larger diameter, while the female threads are of a smaller diameter.

The primary purpose of a reducing bushing is to adapt a larger pipe size to a smaller one, allowing for a smooth and proper transition between different pipe sizes within a plumbing or piping system.

Reducing bushings come in various materials, such as brass, stainless steel, PVC (polyvinyl chloride), or other metals, depending on the specific application and the medium being transported through the pipes. They are commonly used in plumbing, industrial processes, and other fluid transportation systems.

When installing a reducing bushing, it is essential to use appropriate sealants or thread tapes to ensure a watertight and leak-free connection between the pipes. Additionally, it’s crucial to adhere to local plumbing codes and standards while working with pipework and fittings.”
