The rolled groove O-ring gasket joint has decades of proven performance history with steel water pipes. The rolled groove joint consists of a bell and spigot that are formed integrally into the parent pipe cylinder, yielding a joint that is capable of sustaining pressures equal to that of the parent cylinder pipe. The O-ring gasket is contained in the formed spigot groove, and upon insertion of the spigot into the bell, the gasket is compressed between the two ends to form a watertight seal. Given the form of the ends, a properly assembled rolled groove joint is self centering. The rolled groove O-ring joint has a proven history of successful service across a wide range of pressures. Further, historical testing has shown that the parent cylinder will yield and fail prior to failure of the joint itself. Refer to AMERICAN’s Field Service guide for assembly recommendations for a rolled groove O-ring gasket joint.
