A pressure cooker varies in price. A person can buy an expensive pressure cooker or a cheaper pressure cooker. They cost around forty dollars to one hundred thirty dollars.
National Presto does sell replacement parts through an authorized Amazon dealer. You can use their website (gopresto.com) to search by appliance/size (2.5 qt to 8 qt) to find the part that's specific for your pressure cooker. If available, the link will take you directly to the Amazon retailer.
