This is a replacement o-ring gasket for your VCM machines. This seal fits the all VCM 40s and most 44 model machines. This o-ring may not fit the newer VCM 44 lids. The newer lids require a slightly larger diameter o-ring. This must be purchased directly from Stephan. For the smaller 25 model machines, you may still purchase this seal but you will need to cut it down to size.
