IridiumBlackberry Wouldn’t e61 groups be a large diameter and hence their gaskets be too
The E61 group is a standard, and all manufacturers of the E61 groups will make absolutely certain that standard e61gaskets should fit perfectly. This of course is in terms of the ID and OD of the gasket. The variability is in thickness, and this depends on the portafilter the manufacturer has used….the thickness of the ears.
In fact, the less niche a manufacturer of the groups are, the more important it would be to keep to the standard. So Vibiemme which holds the rights to the only “true” E61, Ironically probably have the least standard group…but again the bottom of the group that we’re talking about will be the same I would think.
I’ve never used Cafelat gaskets…i guess it would be interesting to try all the different E671 colours (if there are different ones, and see what they are like on various machines I have…and I have quite a few machines.
