Disclosed is a flexible resilient saddle for effecting a fluid path between a primary channel and a secondary channel, the secondary channel oriented normally to the flow axis of the primary channel, the flow path passing thru an aperture in the primary channel. The inventive saddle includes a longitudinal drum-like bore having a hollow internal surface, the bore having an inner end for interfacing with the primary channel and an outer end opposite thereto for interfacing with an extension of the secondary channel. Further included is an inner peripheral collar extending integrally normally outwardly from an outer area of the inner end of the bore, the inner collar permitting press-fitable, fluid-tight insertion into the aperture and, thereby, into the primary channel. Yet further included is an outer peripheral collar extending integrally normally outwardly from an outer surface proximate to the outer end of the drum-like bore, the outer collar axially separated from the inner collar by a dimension generally corresponding to the wall thickness of the primary channel, the collars having respective opposing facing surfaces for fluid-tight resilient engagement with the inner and outer walls of the primary channel about the aperture. Therein, a fluid-tight fluid path between the primary channel and the secondary channel is achieved through the press-fitable insertion of the inner collar into the aperture of the primary channel.
