The invention provides a one-piece rotator and manifold system and method of operating the same. The system comprises a manifold having an integral stem formed on its proximal end, a O-ring, and a cylindrical outer member. The integral stem has a spigot and a circular flange having a stepped surface which are received in a recess formed in the cylindrical outer member. The O-ring is disposed within the recess and encircles the spigot. During pressurization, the stepped surface is forced axially and radially into the outer cylindrical member and acts to prevent the outer cylindrical member from decoupling from the manifold.
