Cafelat NS-1 Silicone Gasket: Nuova Simonelli Portafilter 71×56.5×9 mm

Cafelat CFL-NS1 Blue Silicone Grouphead Gasket for Nuova Simonelli, Victoria Arduino & La Cimbali

The Cafelat CFL-NS1 Blue Silicone Portafilter Grouphead Gasket is a 9mm replacement gasket designed for espresso machines that use a 71mm x 56.5mm x 9mm group gasket. Made from durable silicone, the CFL-NS1 replaces the standard 9mm rubber group gaskets used on select Nuova Simonelli, Victoria Arduino, and La Cimbali commercial espresso machines.

The flexible silicone construction provides a reliable seal between the grouphead and portafilter while making installation and future gasket removal easier than with traditional rubber gaskets that can harden and compress over time.

Compatible Espresso Machine Brands & Models

The Cafelat CFL-NS1 is intended for compatible machines using the 9mm group gasket configuration, including select models from:

Nuova Simonelli

• Aurelia
• Aurelia II
• Select Appia configurations
• Appia I
• Appia II
• Appia Life

Victoria Arduino

• Adonis
• Black Eagle
• Other compatible commercial grouphead configurations using the 9mm gasket

La Cimbali

• Select grouphead configurations using the 71mm OD x 56.5mm ID x 9mm gasket dimensions

Always verify the gasket dimensions and profile against your original gasket before ordering, particularly because different models within the same brand can use different group gasket sizes.

Important Compatibility Note – CFL-NS1 vs. CFL-NS2

The Cafelat CFL-NS1 should not be confused with the thinner gasket used on certain smaller Nuova Simonelli machines.

The Nuova Simonelli part number 02280020.V corresponds to an approximately 8.2–8.3mm conical group gasket used on select machines, including certain Appia, Oscar, and Musica configurations. The thinner gasket is associated with the Cafelat CFL-NS2 Red Silicone Gasket, rather than the 9mm CFL-NS1.

If your machine uses the 02280020.V gasket, verify the required thickness and gasket profile before purchasing the CFL-NS1.

Replace a Worn Espresso Machine Group Gasket

A grouphead gasket is a critical sealing component between the espresso machine group and portafilter. Over time, repeated exposure to brewing heat, pressure, and moisture can cause rubber gaskets to harden, flatten, or deteriorate. A worn gasket may result in water leaking around the portafilter during brewing.

The Cafelat CFL-NS1 Blue Silicone Grouphead Gasket provides a durable replacement option for compatible commercial espresso machines using the 9mm conical gasket design.

Please Note: OEM and distributor part numbers are provided for identification and cross-reference purposes. Compatibility should be confirmed by matching your espresso machine model, gasket profile, outside diameter, inside diameter, and thickness. The CFL-NS1 is specifically intended for the 9mm gasket configuration and should not be substituted for the thinner 8.2–8.3mm gasket used on certain machines.
