High-quality 3-piece union for your piping system

SCHIEMA is the right place for a high-quality 3-piece union. These unions are specially designed to create a highly reliable, strong and simple connection in various piping systems. Because the union consists of three separate parts, you can easily connect and disconnect pipes without having to dismantle or rotate the rest of the piping system. This makes maintenance and any modifications to your installation quick and efficient.
