Cafelat Gasket - 8.3mm Nuova Simonelli — seal it right the first time
A spare part is bought against the part it replaces, not against the machine's name. The specifications are first on this page so you can hold them next to the component in your hand: the code, the thread, the dimensions and the rating. Anything the maker or the listing doesn't state is left off rather than guessed, and where fitting needs a technician, the page says so.

Send us a photo of the old part, and the code stamped on it if there is one, and we'll confirm the match before you order. On spares that's quicker than reading model lists, because the same machine name covers several generations.
Fitting it
Manufacturer warning - never use a screwdriver or any sharp tool to fit it, this tears the silicone
Two habits save most of the callouts we see. Depressurise and disconnect before you start, because a boiler holds pressure and heat long after it's switched off. And fit seals by hand: a screwdriver used to lever a gasket into a group tears the silicone, and a torn seal leaks under pressure rather than on the bench where you'd notice it. Where the line above says a qualified technician, treat that as the instruction rather than a suggestion — pressure vessels and mains electrical parts are not a place to learn on your own machine.
- Repair instead of replaceA perished gasket, a blocked steam tip or a failed thermostat ends a machine's service, not its life. The part costs a fraction of the machine.
- Identified from a photoSend the old component and we'll match it. On spares that's faster and safer than working from a model name.
- Stated, not assumedWhere a code, a rating or a material isn't published we leave the line out. On a part that holds pressure, a blank is safer than a guess.
Is this the right part for you?
Yes, if you
- Have matched the code, the thread or the dimensions to the part you're removing
- Are replacing a component that's worn, perished, blocked or failed
- Know the rating your machine needs, where the part carries one
- Can fit it yourself, or have a technician who will
Check with us first if
- You're going by the machine's name alone; the same name covers several versions
- The part holds pressure or carries mains electricity and you'd be fitting it yourself
- You're guessing at a dimension — a gasket is sold in millimetre steps for a reason
- A figure you need isn't listed above, which means nobody has published it
In the box
- 1 x silicone gasket
What people ask before buying a spare part
How do I know this fits my machine?
My gasket is 8.3 mm or 9 mm — how do I tell?
Can I fit it myself?
Why does the certification line sometimes say none stated?
Is this an original manufacturer part?
The part number on mine doesn't appear anywhere on this page. Now what?
What if it's the wrong part, or it arrives damaged?
What each specification actually does
Send a photo of the part you're replacing.One picture of the old component, plus any code stamped on it and your machine's model and year, is usually all we need. If it's a pressure or electrical part we'll tell you that too, rather than letting you find out with the machine open.
