Cast Iron Reductions and Extensions
Cast iron reductions and extensions are widely used to adapt pipe thread sizes or extend threaded connections in water, heating, compressed air and industrial piping systems. They provide a strong, reliable and leak-tight solution for both new installations and maintenance work.
At the POLBERIS online store you will find cast iron reductions and threaded extensions manufactured from high-quality malleable cast iron, offering excellent mechanical strength, durability and long service life.
These products are also commonly known as reducing fittings, reducing bushes, reducing sockets, threaded reducers, pipe reducers, threaded extensions, extension fittings, pipe extensions and reducing adapters.
Cast iron reductions and extensions are widely used by plumbers, heating engineers, welders, maintenance technicians and industrial installers for connecting pipes, valves, pumps, radiators, filters and other threaded pipeline components carrying water, air, gas and other compatible media.
Whether you need to reduce a thread size or extend an existing threaded connection, POLBERIS offers a wide selection of durable cast iron reductions and extensions for plumbing, heating and industrial applications.
