Replaced the main seal on the espresso machine for the second time. Seems we reliably get about 3 years out of a seal (machine used 4-6 times per day for 2 people).

Thanks for the corrections!

This one was silicone, and the one I happened to get shipped overnight in March 2021 (it lasted almost exactly 4 years, had to go look it up to confirm it was silicone). Not sure why they chose green. I was trying to highlight the failure and the section of bead tore off. There's more damage from me jamming a hook into it to pull it out. I wish it were easier to get it out for periodic cleaning and inspection. I'll have to look into that.

I replaced it with another silicone gasket (this time off-white) and now have a backup handy.

I'd be interested to know if there's a way to predict failure or if there's a good schedule to follow!
