Cafelat Group Gasket-E61 (Red), Silicone, E61 8mm, SYNCHKG060251

You should really measure your old gasket first, or at least confirm what the OEM size of your original gasket is. I quickly assumed the gasket in my Lelit Mara was a 8mm and ordered accordingly. It fit, but required an excessive amount of tightening to get the portafilter to seal; well past the 6-O-Clock position. I measure my OEM rubber gasket and found it to be 9mm. I reordered the 'blue' 8.5mm gasket and it's a much nicer fit. The portafilter tightens a little past the 6-O-Clock position, but much better than the 'red' 8mm gasket. The silicone is sturdy and seals very well, no leaks like my old rubber gasket was giving me, and I'm getting better shots since I'm not losing pressure to a leaky gasket. If you have an E61-style grouphead this is a good replacement gasket and a nice upgrade from a rubber one. It's inexpensive and very easy to replace. Also, get in there and do a good cleaning while you have the shower screen out. :-)

It was a little tough getting this new gasket in, but my machine was still hot and that didn’t help. Definitely wait until your group head cools down and slowly work the new gasket in. Start by getting one part all the way in then slowly work in a circle easing it in until you’ve gone all the way around. Then seat it firmly by installing your portafilter a few times. Works great in my Diletta Mio (saturated group head). Not a single drop or leak from the first shot.

Installed this on my Rocket Giotto. I'd ordered a yellow gasket that was supposed to fit the Rocket from the place I bought the machine, but that gasket was next to impossible to install and felt too big. This was perfect (8mm) and installed easily. Works well inside the machine and no more leaking (My old gasket was quite old and brittle). One thing to mention: one side of the gasket will have a slightly rounded profile and the other side will be a square 90 degree profile. Make sure you install the gasket correctly - rounded profile fits into the rounded shower screen corner.

This is the second one I have bought; the first Cafelat silocone gasket was for Gaggia Coffee. I have installed it yesterday. Despite what some folks have said (and even Espressoparts, if my memory is not failing me, said "this is not the one we recommend") these work well for me. Fact is, when my Silvia was just bought, the gasket required realy, really superstrong tightening of the portafilter or it leaked. Eventually when 3 years ago I decided, after some more than 10 years to replace it, I bought the original gasket again. Sure enough, it is tough, not soft at all, and required lots of strength to tighten and kept leaking. And recently, after less than 3 years, I have not enough strength to tighten it. So, remembering my experience from 4 years ago when I replaced the gasket on my Gaggia Coffee (which I am sure was ... 20 years old and the extraction really took some doing) and was impressed with the results: the tightening required normal effort and no leaking was observed, I bough the same for the Silvia, in spite of the Espressoparts recommendation. Well, I am happy: I duplicated the Gaggia result: the tightening requires just a normal human effort, and no leak is observed. I know that over one year of constant use my Gaggia did not develop any leaks (I stopped as it was my office machine and during the pandemic I have been working from home). And then I kept using it intermittently (took on trips in a car) and it was, and still is fine - I have just resumed normal use by having returned to the office full time. So. Not sure what is expected, life-wise, from a 10-dollar gasket, but to me it is totally worth buying and is, in my opinion, better than the original

Well, for the price, this is a fine gasket. It's cut cleanly and just the right size. Stuck it in my Bezzera BZ group machine no problem. It is thicker than the OEM gasket that Bezzera sells, so my portafilter doesn't need as much turn to lock in place. That's ok with me, though. The silicone is more dense and more durable than the rubber OEM gaskets use, and, when I hit that resistance locking the portafilter, I know both that I won't get leaks and that I'm not damaging the gasket. Yay for that. The docked star is docked because other silicone gaskets generally come with a screw type tool that can be used to help remove an old gasket. The group head gasket on an espresso machine can be hard to wiggle out because it's wedged into the group head. A hook with a threaded screw would have been a lovely inclusion. I spent a good hour trying to find something around the house to use before eventually landing on a Swiss Army Knife corkscrew. If you buy this, think ahead on what tools you will need to remove the old gasket because this gasket does not come with any such tool.

I wasn't sure if I should get the 8mm or 8.5mm gasket, but the 8mm gasket ended up working out well for my Rocket Appartamento that was previously leaking due to a very old (original) gasket. No more leaks and the portafilter catches nicely into the group head.

Bought this for my ~2006 Gaggia Baby Class, fit right in. Easy to remove I gave 3 stars for removal, but this is for the old hard rubber gasket that was in there. I removed the base of the espresso machine and drilled severla small holes into the old rubber-do not drill into the boiler, you can feel the bit stop-STOP then. Clean the old gasket material until the slot is free of any junk, take the time to do this and this will slip right in. It's been in for about a month and all leaks have stopped, wonderful! Best part of this is when you put the basket back in, it will slide in and have give,and slide right of center just like when it was new! I would definitely buy this again. If it fails, it won't be like removing the cement that rubber turns into.

As advertised. Got here quick and worked great! I got this one to replace the original for my Simonelli Oscar 1 and it works better than the original - very tight fit, no leaks.
