Description

This type of coupling is used to connect two pipes of different diameters together. It has one end that fits onto a larger diameter pipe and the other end that fits onto a smaller diameter pipe. The coupling is designed to reduce the pipe size gradually to allow for a smooth and continuous flow of fluid through the piping system.

Made from high-quality polypropylene material, this fitting is resistant to corrosion and impact damage, making it ideal for use in industrial, commercial, and residential applications.
