This genuine Presto replacement set includes a sealing gasket and a pressure regulator plug for 3- and 4-quart pressure cookers. The gasket fits around the inner rim of the lid and creates a tight seal between the lid and the cooking pot during cooking.

It is compatible with 14 Presto 3- and 4-quart pressure cooker models, including aluminum 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.
