This 2" slip is specifically created to accommodate both flexible and rigid pipes with a 2" internal diameter, as well as 2" spigots. The true dimensions are slightly larger in order to compensate for the thickness of the pipe..
This 2-inch spigot is equivalent in size to a pipe with a 2-inch inside diameter. It can be used with a 2-inch slip fitting.
Sweep elbows provide a higher water flow rate compared to sharp turns.
