Threaded Cross is a type of pipe fitting used in plumbing and industrial piping systems, and this easy-to-install threaded cross is favored for its convenient disassembly in maintenance scenarios. It is designed to connect four pipes at 90-degree angles, forming a cross shape. Unlike butt weld or socket weld fittings, threaded crosses use threaded connections, which means the pipes are screwed into the fitting rather than welded.
Threaded Cross is a pipe fitting with four threaded openings arranged at 90-degree angles, used to connect four pipes in a piping system. It allows fluid or gas to flow in four directions and is installed by screwing threaded pipes into its ends, making this practical threaded cross a go-to choice for flexible pipeline configurations.
Made from materials like stainless steel, carbon steel, or brass, it is commonly used in low to medium-pressure systems such as plumbing, gas distribution, and irrigation.
Its key advantages include easy installation, reusability, and versatility. However, it is not suitable for high-pressure or high-temperature applications due to potential leak risks at threaded joints.
