Has anyone got an Omega supercharger? Are they good?

Does anyone know the size of the dowdy seal that is on the air hose on for the Omega. I checked mine and it is crushed pretty good. I am going to call Todd fro AOA tomorrow but I would like to place a order today. Its the seal on the male end that screws into the top of the compressor for the supply

I am sure someone knows this, please PM me or give me a shout here. Thanks....Pete
