WMF Perfect Ultra + Perfect Pro spare part Cooking signal seal for pressure cooker 2.5l - 8.5l. The cooking signal seal is suitable for the WMF pressure cookers of the "Perfect Ultra" and "Perfect Pro" series. The pressure cooker with the knack in the handle. Sometimes a masterpiece can only be created from exquisite ingredients if you take your time. But sometimes cooking can't be fast enough. In this case, the WMF pressure cooker not only saves you time, but also a whole lot of energy. And that saves vitamins and nerves. The WMF Perfect Ultra pressure cooker stands out with its trend-setting design and maximum ease of use. This is ensured above all by the all-in-one rotary knob on the handle: opening and closing, preselection of the cooking level as well as automatic steaming - everything is controlled via this central control element. Thanks to visual and acoustic signals, the integrated timer ensures that food is cooked to the point. The gentle automatic steam release of the WMF Perfect Ultra ensures that the steam escapes gently and the pot can be opened easily and safely. Thanks to the flame protection on the pot and side handle, the WMF Perfect Ultra is also suitable for use on the gas cooker. To ensure that you enjoy your steam pot for a long time, the WMF Perfect Ultra is made of indestructible Cromargan. And convenient cleaning is also taken care of: the handle can be removed, and the pot and lid are dishwasher-safe. Available are four pots of different sizes, one pan and two sets.
