Union Cross

A union cross is a form of pipe fitting that connects four pipes in a cross-like configuration at a central location. It has four female-threaded apertures that allow pipes with male threads to be connected. Union crosses are often designed with a central nut and two independent nuts on each side of the cross, allowing for easy assembly and removal without interfering with the other pipes. They are available in a variety of sizes and materials to fit various pipe types and fluid system requirements.

A union cross’s principal function is to allow fluid flow in numerous directions from a central point. Union crossovers promote fluid flow between different portions of the system by joining four pipes at right angles. Their union nut design allows for easy maintenance and replacement without the need to remove other linked pipes, making them highly adaptable connections in fluid systems.
