I have purchased many guages over the past few years thinking they were faulty. The guages were likely not the issue but the white gaskets. Recently, when I called Presto complaining that another guage didn't work, I was told to go the local Extension Office to have it tested. My response was that when it sounds like it is going to explode and the guage shows low pressure, I assume it does not work. This is when I learned that the issue is the white gasket. They now have a black gasket for only a few dollars. When you see the design, you will understand why the white gasket was not a good design. Amazon does not offer the new black gasket but if you go to goPresto, it is part #81751.
