Meteorological Influences on Mass Accountability of Aerially Applied Sprays

Disclosed is a joint system for connecting a smooth walled end portion of a pipe to fittings or other pipe. The smooth walled end portion of the pipe has a gasket attached thereto which covers a portion of the end of the pipe and a portion of the outer surface of the pipe adjacent to the end. The fitting or other pipe has a bell end attached thereto with the inner surface of the bell provided with cylindrical surfaces of different diameters separated by a surface perpendicular thereto. When the joint is assembled, the gasket engages a cylindrical surface and the perpendicular surface.
