A one-way cross-slit valve formed of an elastomeric material and comprising a foreshortened hollow cylindrical body having first and second ends, a body wall, and an axis and a passageway entirely through the body, the passageway being intercepted by and movement of any fluid therethrough controlled by a transversely extending continuous ridge and valley wall structure, there being two ridges extending substantially diametrically and intersecting at about the axis of the cylindrical body, the ridges constituting apices of folds in the ridge and valley wall structure, and the apices being both slit therethrough the wall at the intersection to provide a cross-slit, the ridge and valley wall structure being integrally formed with and circumferentially confined by the cylindrical body wall whereby the cylindrical body wall provides hoop strength confinement for the apices, and wherein said cross-slit is essentially coplanar with said cylindrical body second end.
