An ostomy body side member with a sealing member is provided. The sealing member has a fixed base member defining an opening having a first diameter and a resilient sealing element comprising a stoma receiving orifice defining an inner boundary. The inner boundary of the stoma receiving orifice has a second diameter that is smaller than the first diameter of the frame. The sealing member is also provided with at least one adjustment member coupled between the fixed base member and the resilient sealing element. Furthermore, an alignment member for adjusting the tension of the at least one adjustment member is provided thereby allowing the diametrical dimension of the stoma sealing orifice to be adjusted from a first diameter to a second diameter.
