OD (Outside Diameter)

Outside Diameter (OD) refers to the measurement of the outer width of a pipe, tube, or fitting, which is crucial for ensuring compatibility and proper fit in plumbing systems. OD is used to identify the size of pipes and fittings, helping to determine the appropriate connections and flow rates. It is particularly important for pipes made from materials like copper, PVC, or PEX, where accurate sizing is necessary to maintain system efficiency and prevent leaks. Understanding OD is essential for selecting the right pipes and fittings, ensuring compliance with industry standards, and achieving secure connections.
