Sealing Ring Residual Pressure Safety

Original replacement sealing ring for the residual pressure safety mechanism of WMF pressure cookers. It keeps the safety valve sealed so any pressure remaining in the pot is released in a controlled way and the lid can only be opened when it is safe to do so. Made from soft silicone, this small gasket hardens and wears over time; regular replacement is recommended for best performance and safety. Compatible with WMF Perfect, Perfect Plus and Perfect Pro pressure cookers. Easy to fit and remove by hand and simple to clean with warm water.
