About this item

• Is This the Right Gasket? - Check the date stamp located on the bottom of your canner; it will be displayed in a fraction format indicating Month and Year. This gasket is compatible with Mirro and Mirro Matic Canners manufactured prior to January 1983. It is not suitable for Mirro canners or cookers if the model number starts with 92***.
• Customer Service - Our highly trained staff is just a phone call away if you have any problems or questions. We are located in Hillsvile, Virginia.
• Original Part - This is an Original Equipment Manufacturer Part. In 2007, SEB Corp granted explicit authorization to Red Hill General Store for the procurement of Mirro / Mirro Matic pressure cooker components directly from the original manufacturer.
• Premium Gasket - Our gaskets are crafted from top-tier, food-grade silicone rigorously tested to withstand high temperatures and pressures. Originally, our gaskets were white, a design that persisted until the 1990s when they transitioned to black neoprene gaskets. In our continuous pursuit of excellence, we have recently upgraded to food-grade silicone, enhancing both sealing performance and longevity.
