This float valve kit fits Duo series pressure cookers: Duo 3, 5, 6 Quart, Duo Plus 3, 6 Quart, Smart 6 Quart, Smart Wifi 6 Quart. The float valve and lid are small parts that play a big role in how your pressure cooker functions. The silicone seal wears out over time due to the heat and pressure inside the cooker. You might also lose one while washing the lid, so it's good to have spares on hand. Well-made and durable. The silicone seal is made of safe and durable silicone; odorless.
