Flair Espresso O-Ring Sets – Replacement Seals for All Flair Models
A slight drip at the brew head. A plunger that no longer glides quite as smoothly as it used to. The needle of the pressure gauge twitching nervously. These are the moments when your Flair is telling you: an O-ring needs some attention. No drama, no repair – just a few minutes of care that give your daily ritual back its calm.
Coffee Coaching Club is a Swiss importer of Flair Espresso and stocks the original Flair O-ring sets for every model in the family. You choose your model, we deliver the matching set – throughout Switzerland and to Liechtenstein in 2 to 4 working days.
What These O-Rings Do
O-rings are the most inconspicuous parts of your Flair and, at the same time, the most important. They keep the pressure where it belongs. They stop water from escaping where it shouldn't. They make sure the plunger glides smoothly and that the pressure gauge measures what is actually happening in the brew cylinder.
Over time, the silicone hardens. Heat, pressure changes and the occasional cleaning leave their mark – that's not a weakness of the Flair, it's simply material physics. A change every one to two years, depending on how intensively you use it, keeps any Flair precise. Original Flair O-rings are made of food-safe silicone, designed precisely for their respective seats, and reproduce the original clearance.

Which Set Fits Your Flair
If you have a Flair 58, 58+ or 58+2, you need the 58 set. The brew head rings have a larger diameter than on the other models – they're not interchangeable.
For the Pro series – PRO, PRO 2 and PRO 3 – there's one shared set. The three generations share the internal dimensions of the brew group. If you're not sure whether you have an older or newer generation: the set fits all three.
Classic, Standard and Signature belong together. These three non-electric models use the same brew cylinder and the same plunger geometry. One set covers all three.
NEO Flex and Flair 2GO are the more compact, lighter models in the family. They make do with a set of four rings because their design has fewer sealing surfaces.
The 49 PRO is the youngest Flair and uses a 49 mm portafilter instead of the 58 mm of its big sister. Its own set, its own geometry – don't mix it up with the PRO set.
When a Change Makes Sense
The O-rings in your Flair are surprisingly durable. With normal use they last one to two years, often longer. But there are signs to watch for: a slight drip at the brew head during pre-infusion, water running down the stem, a pressure gauge that suddenly twitches or no longer moves off its zero position. If a ring has visible cracks, looks brittle or has lost its shape – it's time for a change.
If you pull several espressos a day, you can swap the set as a precaution after 12 to 18 months. If you only use your Flair at the weekend, you'll easily get two to three years out of it. Espresso is complex but it isn't rocket science – and maintenance is part of the ritual, not a source of stress. That's our observation; others may see it differently.
Available in the Showroom
If you'd like to have your Flair looked after in Bern or Zurich, you're warmly invited. Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. Drop us a quick line at [email protected] before your visit, and we will check whether the product you have in mind is currently there. Come by even if you don't need an O-ring, simply for a coffee and a chat. You're part of the community the moment you walk in – whether you take something home or not.
While You're at It
If you're looking after your Flair anyway, it's worth taking a look at two related areas: good cleaning products for machines and grinders keep the brew path in shape just as long as the seals. And if you want to refine the brewing experience itself, you'll find accessories such as the preheat funnel, bottomless portafilter or Pressure Gauge Kit in the Flair Espresso Collection.
For your daily setup around the Flair, one thing holds true: a good grinder makes the biggest difference. Affordable and precise, we recommend the Comandante C40 as a hand grinder. If you want an electric one, you'll find the VS3 in the Varia Collection. For more control, it's worth looking at Weber Workshops or Option-O Lagom. A precise Acaia scale or a compact Normcore scale makes every shot easier to follow.
FAQ
How often should I change the O-rings on my Flair?
That depends on how you use it. With daily use we recommend 12 to 18 months; with occasional use the rings last two to three years. Visible cracks, brittle material or a slight drip are clear signs it's time to change them.
Which set fits my Flair?
Choose the version according to your model name: 58 / 58+ / 58+2 for the electric 58 mm models, PRO / PRO 2 / PRO 3 for the Pro series, Classic / Standard / Signature for the non-electric models, NEO Flex / NEO Flex 2024 / 2GO for the compact models and 49 PRO for the newest 49 mm model.

Roastery Tip
After an O-ring change, the first two or three shots often taste ever so slightly different – that's just imagination, but a lovely one. Freshly cared-for equipment changes the moment in the morning. If you're looking for a bean that really shines in the Flair's manual brewing: our full-bodied Cozy Chocolate or the nutty, dense Nutty Delight. For maximum body without any acidity at all, the Very Nutty. If you're in the mood for fruity complexity, Wild Peach is a lively discovery. That's our recommendation, one of many.
