This genuine Presto replacement set includes a sealing ring and an automatic air vent valve. The sealing ring installs around the inner rim of the lid and forms a tight seal between the lid and the pot during cooking.

It is compatible with 14 Presto pressure cooker models in 3, 4, and 6 pints, including stainless steel models.

Presto is the appliance brand of National Presto Industries, a company founded in 1905 in Eau Claire, Wisconsin. It originally manufactured autoclaves for commercial use, then for home use, before introducing its first small kitchen appliances in 1939. Presto also offers genuine replacement parts, such as sealing gaskets for its pressure cookers and autoclaves.
