an axle defining a hollow bore for receiving a liquid output from the ostomy appliance, the axle comprising a curved lateral wall; and
an outlet element comprising a cap arranged concentrically with the axle and an outlet tube affixed to the cap;
wherein a valve opening is defined in the curved lateral wall; and
the cap is rotatable around the axle to move from a closed configuration in which the valve opening is not in liquid communication with the outlet tube to an open configuration in which the valve opening is in liquid communication with the outlet tube;
wherein the outlet valve further comprises at least one seal configured to provide sealing between the cap and the axle around a circumference of the axle and sealing between the intake opening and the valve opening when the outlet element is in the closed configuration;
wherein the at least one seal comprises a continuous first seal configured to provide sealing between the cap and the axle around a circumference of the axle and wherein the distance between the first seal and a basal end of the axle varies around the circumference of the axle.
