A straight cross is a plumbing fitting that connects four pipes of the same diameter at a perpendicular angle, forming a cross shape. It is used in both water supply and drainage systems where multiple lines need to intersect or branch off. Straight crosses are typically made from materials like PVC, copper, or brass, depending on the application. Proper installation of straight crosses ensures even distribution of flow, minimizes pressure drops, and maintains system efficiency. They are secured using appropriate joining methods, such as soldering, threading, or solvent welding, based on the pipe material.
