La Marzocco Copper Sealing Ring 27x21x1.5 mm – Original Spare Part
A single copper ring, flat, unassuming, barely bigger than a fingernail – and yet the exact point where a threaded fitting inside the machine either stays dry or doesn't. Copper deforms just enough under torque to even out every small irregularity, and that's exactly what makes it the material of choice for sealing rings on threaded connections.
Over time, even copper loses its ability to deform – once a fitting has been loosened, the same ring often no longer seals reliably when retightened. A new ring brings the connection back to being tight, for little effort and even less cost.

Frequently Asked Questions
What is this sealing ring used for?
It seals threaded connections inside the machine, wherever copper rings are used for their slight ability to deform.
How do I know the ring should be replaced?
Once a fitting with a copper ring has been opened, it's worth fitting a fresh ring when closing it again.
Can I replace it myself?
As part of a service, yes, though this requires loosening the relevant fitting. If you're unsure, we're happy to take care of it as part of our service in Bern or Zürich.
Can I see the product before buying?
Yes, in our showrooms in Bern (Gerberngasse 44) and Zürich (Hagenholzstrasse 50b) you can experience the original spare part live.
The Roastery Tip
A tightly sealed machine deserves beans that show just as much care. Our main recommendation: Cozy Chocolate and Nutty Delight, dense, aromatic, full-bodied. For maximum body with no acidity at all: Very Nutty. For anyone wanting to discover a fruity experience: Wild Peach, lively and always a discovery. Our recommendation from the roastery, one of many.
