A reducing coupling is a versatile plumbing fitting designed to connect pipes of different diameters, facilitating a smooth flow transition between varying pipe sizes. It provides a secure, leak-proof connection that maintains system pressure and efficiency, making it ideal for plumbing, heating, and industrial systems. Constructed from durable materials like stainless steel, and brass, reducing couplings are resistant to corrosion, pressure, and mechanical damage. Easy to install, they reduce the need for complex fittings, making them a reliable solution for connecting pipes in various environments.
