The gasket has minimum exposure to steam inside the cooker, does not rub every time the product is opened and closed - so lasts longer.Suitable for gas, electric, ceramic and halogen cooktops.Stay-cool handles. Fixed sturdy pivot does not put pressure on the plastic handles as it is a part of the metal handle itself. Thus handles last longer.Recommended for use on gas stoves.
