Fitting and joints are a critical aspect of PVC piping installation. Overlapping joints are used to connect pipe lengths and fittings. Whether using threaded or solvent-welded connections, there is an expanded-diameter section that allows entry of the previous pipe. The expanded-diameter portion is the female end and it is often called a socket, bell, rip or hub. The male end is frequently called a slip, mip or spigot.
An advantage of PVC pipe is the ease of connections. In onsite wastewater applications, the most common means of connecting pipe is with solvent-welded fittings. A strong solvent is used to chemically weld
