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 .087 inch (2.21 mm) thick.   The gasket is made of Nitrile Rubber, suitable for use with oil and water, same as your OEM gasket. Is your OEM Pressure Switch leaking badly, hissing? Why buy another pressure switch when all you need is a gasket? Your gasket has over time absorbed oxygen making it less and less flexible and unable to form an air tight seal causing it to leak more and more. Also, your custom made OEM switch is calibrated to your compressor and better than those cheap knock offs out there and it is a lot simpler to change the gasket than it is to change the switch! 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. Don't let it! If that spring loaded assembly flies apart, you will find it nearly impossible to put it back together! Simply back out the 4 mounting screws. Then back the switch assembly off from the port plate just enough to slip the old gasket out and 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 this procedure fixed it!
