Portafilter gasket 73x57x9mm

Every brewing group uses a portafilter gasket. In this case it is a 73x57x9mm gasket. In this case they are made from a food grade nitrile butadiene rubber(Nbr)

The OD and ID of 73x57mm is quite a standard size. You will see this size with brands like Expobar, Vibiemme (VBM), La Scala, Bezzera, Faema and Azkoyen. This doesn’t mean that these brands don’t have brewing groups which use a different size of portafilter gasket.

In the case that your portafilter seals off too far, but it seals, you can try a 0,5 or a 0,8mm paper filler above the portafilter gasket.

If you are not entirely sure if the 73x57x9mm is suitable for your brewing group, please send us a message and we might be able to help you with this.
