This generic gasket will fit any port plate as long as the dimensions are 2.11 inch  (53.59 mm) by 2.11 inch (53.59 mm) as show in the picture. This gasket is .030 inch (.762 mm) thick. Some of the mounting holes are a slightly rough cut. However, that in no way will impact the installability or functionality of the gasket. These gaskets have a 1000psi tensile strength. In other words, if your compressor operates below 1000psi, this gasket will work for you.  Is your OEM Pressure Switch leaking badly, hissing? Why buy another pressure switch when all you need is a new gasket? Your gasket has over time, absorbed oxygen making it less and less flexible to the point that it can no longer form an air tight seal causing it to leak more and more. Also, your custom made OEM switch is calibrated to your compressor where as the cheap knock offs out there are not! My generic gasket is made of Nylon reinforced Neoprene Rubber, suitable for use in a moderate oil, and water environment, same as your OEM gasket.  To install this gasket, relieve pressure to the switch if there is any pressure left. I recommend you empty the tank. Swapping out your gasket is a breeze! Just don't let go of that spring loaded switch assembly when you are backing out the 4 screws mounting it to the port plate. You will see the switch assembly trying to separate as you back out the screws. Don't let it! If that spring loaded switch flies apart, you will find it next to impossible to put back together!  Simply back out the 4 screws in the port plate while leaving them in position. Then lift the switch assembly off the port plate just enough to slip the old gasket out and slide the new one in. Push the assembly back into place, run the screws back in and you're home free. My 4-port pressure switch was leaking badly, hissing, on my Sears 5hp/20gal Air Compressor and one of these gaskets fixed the problem!
