Abstract
A spray arm for a dishwasher is provided, comprising a first portion having a first engaging surface extending about an outer surface periphery thereof, and a second portion having a second engaging surface extending about the outer surface thereof and complementarily configured with respect to the first engaging surface. The engaging surfaces form a laterally-extending, non-linear interface upon engagement such that the first and second portion outer surfaces are directed away from each other. The second portion also includes a flange extending about the outer surface, and disposed laterally outward of and spaced apart from the second engaging surface, to define a channel having a depth extending across the interface. A securing material is introduced into and substantially fills the channel, and extends across the interface and about the first portion outer surface periphery, to secure the first and second portions together. An associated method is also provided.
