3Pcs 54mm Silicone Steam Ring, Grouphead Gasket Replacement Part, Replacement Sillicone Gasket for Most coffee machines 870/878/880/860/840/810/450/500/875/878

These group head gaskets are a good thing to have around the house. When the group head starts leaking and the gasket needs replacing, the last thing you want to do is figure out which piece is needed, order, then receive it. It's more likely you're here right now because you need one right now. At least it should arrive quickly from Amazon. I can't speak to what machines these gaskets will fit, but I can say they do fit my Breville BES840 Infuser.

There's not much to criticize about an item like this. It either works or doesn't and this works. I switched it out for the original gasket that came with my Breville Barista Pro and it was a perfect fit. Quality wise, it seems just as good to me and when I ran the machine, it worked without issue. Not to mention it came with 3 gaskets, which I don't see myself ever needing all 3. I got this just in case there was ever an issue, but with 4 gaskets now, I think I'll be good to go if anything happens lol. The only difference is it's a little whiter looking that the original, which doesn't matter at all as you don't see it, and it's a little bit stiffer. That doesn't affect the function at all. For the cost and amount you get, there's definitely no beating it. If you need a new gasket for your Breville machine, this is the one.
