Replacement handles are the most common requirement, normally after a cooker has been dropped onto a hard floor. Luckily all handles are user replaceable, only requiring a cross head screwdriver.
Whilst the blue silicone gaskets can last for years with care, they will
need to be replaced when the cooker will not come up to pressure properly. To check the required part number look on
the inner surface of the gasket. The part
number will be embossed onto the surface.
Measuring a gasket is not recommended.
You will need to locate the model number of your Duromatic and year of manufacture. Helpfully, Kuhn Rikon etch all this information onto the base of each and every cooker during manufacture. An example is shown here with the required information underlined.
Once you have this information you can visit the Cookability Interactive Spares Finder.
