This gasket is designed for Mirro and Mirro Matic Canners manufactured before January 1983. To determine if this is the correct gasket, you should identify the date stamp located on the underside of your canner, which will be presented in a fractional format representing Month over Year. If the model number of your Mirro canner/cooker begins with 92***, this gasket will not fit.

The S-3440 Mirro Gasket is an Original Equipment Manufacturer (OEM) 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.

Our gaskets are crafted from top-tier, food-grade silicone that has been 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.

If you have any problems or questions, our highly trained staff is just a phone call away. We are located in Hillsvile, Virginia.
