1. A valve for a hub of a sheath, catheter, or other tubular device, comprising:
a valve body comprising a first face, a second face opposite the first face and an axis extending between the first and second faces;
a first slit having a first width perpendicular to the axis that is less than a width of the first face and a first length extending substantially parallel to the axis from the first face towards the second face to a first intermediate location within the valve body;
a second slit having a second width perpendicular to the axis that is less than a width of the second face and a second length extending substantially parallel to the axis from the second face towards the first face to a second intermediate location within the valve body; and
a bore extending along the axis between the first intermediate location and the second intermediate location such that the first slit and the second slit are spaced apart axially from one another on either side of the bore, the bore having a cross-section perpendicular to the axis that is smaller than the first width and the second width,
wherein the valve body comprises:
a first valve portion comprising the first face and first slit and defining a first intermediate face,
a second valve portion comprising the second face and second slit and defining a second intermediate face,
the first and second intermediate faces placed against one another to provide the valve body.
