La Marzocco O-Ring for LEVA / Smart Steam Backflush Screw – Original Spare Part
Once a day, without detergent, a few seconds – backflushing is part of the ritual of every machine meant to last with care. At the end of this small routine sits a screw that closes the backflush channel, sealed by a tiny O-Ring.
On the LEVA and on machines with Smart Steam, this O-Ring sits in the same spot: small, unassuming, but responsible for making sure no pressure escapes sideways during backflushing.
A seal that works quietly – until it doesn't
Rubber seals lose elasticity over time, especially from repeated heat and pressure. An O-Ring that has become brittle no longer seals completely – an effect that doesn't show up immediately, but becomes more noticeable with every backflush. Since the backflush screw is moved regularly during daily care, this O-Ring is one of the parts most likely to need replacing.
The replacement is small, but important for a system that depends on tightness: the daily backflush routine without detergent and the more thorough cleaning roughly every 50 shots.

The Roastery Tip
A well-maintained machine deserves beans that deserve 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 curious to discover a fruity experience: Wild Peach, vivid and always a discovery. Our recommendation from the roastery, one of many.
