Union

A brass union is a type of pipe fitting that connects two pipes while allowing for easy disconnection and reassembly. It consists of three parts: two end pieces and a central nut that tightens to secure the connection. The design allows for pipes to be joined without having to turn the pipes themselves, making it ideal for systems where regular maintenance or future modifications are needed. Brass unions are valued for their corrosion resistance, strength, and ability to provide a leak-proof seal. They are commonly used in plumbing, HVAC systems, and various industrial applications.
