Features: brand new and high quality Float valve and silicone gasket are part of the pressure cooker cover and are essential parts for the work of the pressure cooker. The float is made of metal, and the sealer is made of flexible plastic, which is odorless, non-toxic and safe to use. Easy to install, first insert the smaller side into the cover (from outside to inside), then put the sealant on the smaller side so that it is in the groove of the valve. Silicone gaskets are often washed off, making the float valve loose and the pressure cooker unusable. This spare part can make your malfunctioning cookware work like new. This float and sealer can be applied to various types of electric pressure cookers.
