PVC Gasketed Pipe and the Role of Insertion Lines
If you’ve ever been involved in a water or sewer project, chances are you’ve worked with PVC gasketed pipe . It’s one of the most common materials used in underground utilities, and for good reason: it’s tough, flexible, and built to last. But here’s something many people don’t realize—the performance of the pipe depends heavily on a small mark called the insertion line . What Makes Gasketed PVC Different? PVC pipe with gasketed joints is designed with two ends: one side is the bell (the socket) and the other is the spigot (the smooth end). Inside the bell is a rubber gasket that seals when the spigot is pushed in. This system has a big advantage over glued pipe: the joints stay flexible. That means the pipe can handle ground shifts, temperature changes, and pressure surges without breaking or leaking. For cities and contractors, that translates to fewer repairs and longer system life. The Purpose of the Insertion Line Take a look at the spigot end of a gasketed PVC pipe and you...
