Brasilia Conical Portafilter Holder Gasket 66x56x6.4mm

Conical Portafilter Holder Gasket 67 x 56.5 x 6.4 mm – Brasilia

Conical Portafilter Holder Gasket – 67 x 56.5 x 6.4 mm is a specialized espresso machine group head gasket designed for select Brasilia espresso machines. This commercial-grade conical filter holder gasket features a tapered profile that provides a secure, pressure-resistant seal between the portafilter and group head during espresso brewing.

Also commonly identified by the generic size 66 x 56 x 6.4 mm and commercial reference BF…1 / BF001, this gasket is particularly associated with early-generation and first-series Brasilia espresso machines. Its conical design is important for proper fitment and should not be confused with later flat-style Brasilia gaskets.

Key Features

• Gasket Type: Conical Portafilter Holder / Group Head Gasket
• Outside Diameter: Approximately 67 mm, tapering through the conical profile
• Inside Diameter: 56.5 mm
• Overall Thickness: Approximately 6.4–6.5 mm
• Cone Step Thickness: Approximately 4 mm
• Profile: Tapered / Conical
• Application: Commercial, lever, and select domestic espresso machines
• Designed for: Specific legacy and early-production group head configurations

The tapered cone profile is designed to wedge securely into the group head, helping create a reliable seal during high-pressure espresso extraction. A properly fitted portafilter gasket helps minimize leaks around the filter holder and maintain consistent brewing pressure.

Compatible Brasilia Espresso Machines

This conical portafilter gasket is suitable for select first-series and early-production Brasilia machines, including:

• Brasilia Belle Epoque – early/vintage production and select lever or semi-automatic versions
• Brasilia Century – first-series models
• Brasilia Firenze – early production models

Important Fitment Information

Verify the gasket profile and dimensions before ordering. Early Brasilia Belle Epoque, Century, and Firenze machines can use this conical 67 x 56.5 x 6.4 mm gasket, while later versions of these machines may use a different flat 70 x 57 x 8 mm gasket.

The later flat gasket is commonly associated with BF011, so this conical gasket should not be substituted based solely on the machine model name. Production year, group head design, gasket profile, and existing gasket dimensions should be checked to ensure compatibility.

Reference & Cross-Reference Part Numbers

Replace a Worn Espresso Machine Group Gasket

Over time, espresso machine portafilter gaskets can become hardened, compressed, cracked, or deformed from repeated exposure to heat, water, coffee oils, and brewing pressure. Replacing a worn gasket can help restore a tight portafilter seal and reduce water leakage around the group head.

This 67 x 56.5 x 6.4 mm conical portafilter holder gasket is an excellent replacement choice when servicing compatible early-production Brasilia and cross-compatible espresso machines.

Before purchasing, compare the dimensions and conical profile of your existing gasket to ensure the correct fit.
