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.

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?
Match the part rather than the machine. Read the code stamped on the component you're replacing, or measure it, and compare that with the specifications on this page. Model names cover several generations and regional versions, so a compatibility list narrows the field without settling it. Send us a photo of the old part with your machine's model and year and we'll confirm before you order.
My gasket is 8.3 mm or 9 mm — how do I tell?
Take the old one out and measure its thickness, or check your machine's parts diagram. They look nearly identical in a photo and they are not interchangeable: too thin and the portafilter over-rotates and leaks, too thick and it won't lock in far enough. If you can measure it with calipers, do. If not, send us the machine model and we'll look up which thickness it takes.
Can I fit it myself?
It depends entirely on the part. A steam tip, a gasket, a diffuser or a crank are owner-serviceable with basic tools and care. A safety valve, a thermostat or a pressure fitting is not: those sit in a pressurised boiler or on mains electricity, and the installation line on this page says so where it applies. Read that line before you order, and if it names a technician, arrange one.
Why does the certification line sometimes say none stated?
Because we only publish what is actually claimed. Some parts here carry a formal certification — a safety valve may be CE and PED marked, a gasket may have a food-grade test report — and some are sold without any certification claim at all. Saying so is more useful than silence, particularly on a part that sits in a boiler or touches the water that reaches the cup.
Is this an original manufacturer part?
Read the brand and the part number lines. Some items here are branded components from the original maker, some are third-party parts sold to fit named machines, and where a part replaces an original code that code is listed. None of that is hidden: if a part is a compatible replacement rather than an OEM one, the specifications say what it replaces and the rest is for you to weigh.
The part number on mine doesn't appear anywhere on this page. Now what?
Send it to us. Part codes are how spares are actually identified, and we can usually trace a code to the current equivalent even when the listing doesn't name it. That's a better outcome than ordering something that looks similar.
What if it's the wrong part, or it arrives damaged?
If you change your mind, you can request a return within 3 calendar days of delivery, as long as the item is unused, in its original packaging and in resalable condition — so check the fit before you attempt to install it. If it arrives damaged or defective, tell us within 7 days and send photos or video of the issue. Returns need our approval first, so start with a message or email to info@scorestore.ae. Sale and clearance items can't be returned unless they're confirmed defective.
What each specification actually does
Model / OEM part numberNuova Simonelli 8.3 mm conical group gasket (NS Red)
The part number is how spares are identified, and it's worth more than any description. A code matches one component with one set of dimensions; a name like "steam tip" matches dozens. Write yours down somewhere you'll find it, because the next time this part wears out the code turns a diagnosis into a two-minute order.
Replaces / original part codeReplaces the original rubber group gasket
This line is the bridge between what you have and what you're buying. Where it names an original code, you can check it against the component you're removing and be certain. Where it says an accompanying piece isn't included, read that carefully — on spares the commonest disappointment is a part arriving without something the buyer assumed was attached.
Compatible machines / brandsOlder Nuova Simonelli models - Program, Optima, Personal, Program VIP, Premier, Premier Maxi, Mac Digit, Mac Cup, Mac 2000, Appia, Appia II, Oscar, Oscar II, Musica
Read it as a shortlist, not a promise. Makers change components mid-production and sell different versions by region, so a model name on this list tells you the part is probably right and never that it's certainly right. Where the line itself says to confirm the exact model, that caution is deliberate. Match the old component and the list becomes a cross-check rather than the decision.
Compatible group / portafilter size8.3 mm gasket - check whether the machine takes 8.3 or 9 mm before ordering
Group families are the useful unit for anything that sits in a group head. A part cut for an E61-style group fits the many machines built around that design, which is why one diffuser covers a long list of brands. Within a family, though, the millimetre figure still has to match — the family gets you to the right shelf, the dimension gets you the right part.
Size / dimensions (mm)71 outer diameter x 56.5 inner diameter
On seals and rings the dimensions are the product. An o-ring is defined by its inner diameter and cord thickness, a gasket by its outer and inner diameter, and a millimetre in either direction is a part that leaks or won't seat. If you can measure the old one with calipers, do — and if you can't, tell us the machine and the position and we'll look it up.
Thickness / height (mm)8.3
Thickness is what sets how far the portafilter turns. On a group gasket it decides where the handle ends up and how firmly the basket seals: a gasket that's too thin lets the portafilter rotate too far and weep at the edge, one that's too thick stops it locking home. This is why gaskets are sold in steps like 8.3 and 9 mm rather than one size.
Main materialFood-grade FDA silicone rubber with an SGS food test report
On a part that sits in hot water under pressure, the material is the lifespan. Silicone stays flexible far longer than the rubber it usually replaces, which is why a silicone group gasket is a common upgrade rather than a like-for-like swap. Fluoroelastomer seals are specified where heat would harden an ordinary o-ring. Where the line adds a food-grade standard or a test report, that matters too: this is a part the water passes.
CertificationFDA food-grade silicone, SGS food test report
Certification is a claim, and this line reports whether one is made. On pressure parts a formal marking means the component was assessed against a standard, which is what an inspector or a service engineer will look for. On parts that touch water, a food-grade standard or a test report is the equivalent. Where nothing is claimed we say so rather than leaving the line out, because on a spare part the absence of a claim is itself worth knowing.
Hole pattern / shapeConical with external grooves
Pattern and profile decide how the part behaves in use. Wide holes and narrow holes on the same count of jets steam differently; a conical gasket with external grooves seats differently from a flat one. It's the detail that explains why two parts with the same headline description don't feel the same once fitted.
Installation & careManufacturer warning - never use a screwdriver or any sharp tool to fit it, this tears the silicone
Follow this line as written — most of it exists because the maker has seen it go wrong. Seals go in by hand rather than with a tool, threaded fittings want the correct tape or seal and no more torque than needed, and parts inside the group get cleaned with your regular backflush rather than left to build up. Where it names a qualified technician, that's a boundary, not a formality.
Pack quantity1
Worth reading twice on consumable seals. Gaskets, o-rings and screens are the parts you'll replace again, and having the spare already in the drawer is the difference between ten minutes of maintenance and a machine that's down until a delivery arrives. If you run more than one machine, buy accordingly.
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.
