“PLEASE READ MY MOST RECENT UPDATE. I TOOK IT FROM A ONE TO A FIVE STAR BECAUSE OF THIS DISCOVERY! Original review: September 1: Ordered these about a year or so ago and they worked well, re-ordered them in August 2025 and it is not the same size or quality I ordered previously. I installed the new gasket and water is leaking out everywhere and does not seem to be making a good seal on my Breville BES870XL Barista Express. Doesn't work, waste of money. Update: These were delivered on September 1, 2025. It is now September 7, 2025. It has blown out AGAIN. I never could get it to pull a shot correctly as it did perfectly before, the previous gasket wore out. The first time I installed this it blew water everywhere still and I have messed with it enough that I got it to at least pull a shot, but it's very apparent that the millimeter of the gasket is too loose. Well this morning, seven days later, the gasket came out again. ITS DRIVING ME CRAZY. Save yourselves the headache and go straight to Breville for the parts, which is what I am doing now. Update: September 18, 2025. It blew out again but we figured out why! Everyone with my same machine, there are internal screws that loosen in the group head and cause this to happen. If you drill through outer plastic and access them you can tighten them without disassembling and your gasket won't keep blowing out. You can look up the placement and exact location of the screws and holes you need to drill on YouTube . I reseated the gasket and after tightening the group head screws, it works perfectly.”

“I had my Breville Barista touch unplugged and upside down because of a milk sensor issue. While I was troubleshooting I realized I had never changed the head gasket and figured I should preemptively do it while the machine was out of commission anyway. This gasket couldn’t have been simpler to replace and fit perfectly. I had no issues with it at all and like there was a spare in the pack as well.”

“First set of 2 did Not work but leaked. Instead of leaving a negative review, we contacted Amazon and were sent a replacement set and needed to return the first set. No problem. Replacement set arrived Jan 6, inserted one the 7th and it's been working Great with no leaks and great pressure. We are very pleased.”
