The invention relates to a duplex basket strainerarrangement. Such arrangements include an outer casing having a first basket strainer receptacle at one end thereof, a second basket strainer receptacle at the other end thereof, a center plug receptacle having an inner wall surface and being disposed between the first and second receptacles, inlet means disposed in one side wall of the casing for permitting entry of a fluid into the casing, and outlet means in the other side wall of the casing for permitting exit of the fluid from the casing and a center plug disposed in the center plug receptacle. In accordance with the invention, the center plug comprises an elongated member, circular in cross-section, having an inflow stage and an outflow stage, and resilient means disposed around the periphery of the elongated member between said inflow and the outflow stages. The diameter of the resilient means is greater than the diameter of the inner wall surface of the center plug receptacle adjacent the resilient member, so that the resilient member resiliently engages the inner wall surface to provide a fluid tight seal between the inflow stage and the outflow stage.
