XLG, or Extra Long, refers to plumbing pipes or fittings that have an extended length compared to standard components. Extra Long components are used in situations where longer runs are needed, such as in underground water supply lines, extended vent stacks, or large drainage systems. They help minimize the number of joints or connections required, reducing the risk of leaks and improving system efficiency. Extra Long pipes and fittings must be properly supported and aligned to maintain system integrity and prevent sagging or damage.
