Designed to fit four sizes of our pressure cookers, this WMF glass lid is great for viewing the contents in the pot when keeping your meal hot on the stove. Once your preparation is completed using the WMF pressure cooker, simply remove the lid after the pressure is released, and replace with this glass lid. This lid is also a nice accessory piece for those times when you opt to use the pressure cooker as a regular pot on top of the stove, to make sauces or gravies. Lid fits the WMF 3-, 4.5-, 6.5-, and 8.5- quart cookers.
