A diffuser saddle connection is used for the attachment of diffusers on submerged air laterals in systems that treat municipal and industrial waste water. A top saddle surface and a bottom saddle surface enclose a portion of a feed pipe. A spout attached to the bottom saddle surface is solvent-welded to a tee, which is threadedly engaged to a diffuser. Flexible bushings on a nipple attached to the tee relieve stress on the connection between the diffuser and the diffuser saddle connection. An open end allows water to flow into the diffuser pipe to provide hydrostatic equilibrium and to reduce buoyancy.

1. A diffuser connection, comprising: a threaded nipple, having a longitudinal axis A; a threaded nipple bushing, threadedly engaged to the threaded nipple; and a diffuser, having a longitudinal axis A', connected to the threaded nipple and housing a resilient bushing, wherein stress applied at an angle to the axis of the diffuser results in a deformation of the resilient bushing. 2. The diffuser connection of claim 1, further comprising a check valve abutting said resilient bushing. 3. The diffuser connection of claim 2, wherein the diffuser accommodates a volume of liquid for hydrostatic equilibrium. 4. A diffuser connection, comprising: a nipple having a proximal end, a distal end and a longitudinal axis A; a threaded nipple bushing, threadedly engaged to said nipple; a resilient flow control bushing, distal to the nipple, receiving flow from the nipple, having a longitudinal axis A'; a resilient ring bushing, disposed circumferentially around the threaded nipple bushing, having a longitudinal axis A'; and a resilient disc bushing, receiving the nipple, proximal to the threaded nipple bushing, having a longitudinal axis A', wherein the flow control bushing, ring bushing and disc bushing form, in combination, a resilient seat remaining leak tight around the nipple and threaded nipple bushing upon the exertion of stresses altering the angle between A and A'.
