BIALETTI replacement gaskets and filter set for 1-cup moka pot – 3 gaskets + 1 filter (mpn 800001)

Set of replacement gaskets and a filter plate designed for a 1-cup BIALETTI moka pot. This spare-parts kit contains three rubber sealing gaskets and one metal filter plate that restore the original seal and filtration of small stovetop espresso makers. By replacing worn or hardened components, the set helps prevent steam or coffee leaks, supports correct pressure build-up and promotes consistent extraction for one-cup brewing.

Advantages

The three rubber gaskets provide multiple replacement cycles, allowing staggered changes and longer overall service life for the moka pot. The single metal filter plate reproduces the original filtration surface to maintain even water flow through the coffee bed. The parts are shaped and sized to match common 1-cup models, enabling straightforward installation and reliable sealing when parts show signs of wear or deterioration. Using original-style components reduces the risk of leaks and uneven extraction.

Suitable for

• Owners of 1-cup BIALETTI stovetop espresso makers needing routine maintenance
• Replacing hardened or torn rubber gaskets to restore a tight seal
• Renewing the metal filter plate to improve water distribution and extraction
• Keeping a spare set on hand to avoid downtime from worn parts

Key specifications

• Content: 3 rubber sealing gaskets and 1 metal filter plate
• Compatibility: sized for 1-cup moka pot models
• Material: heat-resistant rubber gaskets and stainless metal filter plate
• Function: sealing ring replacement and filtration plate replacement for stovetop espresso makers
• Purpose: restore sealing, prevent leaks and support pressure build-up for proper extraction

How to use

Allow the moka pot to cool fully and disassemble it according to the manufacturer’s instructions. Remove the old gasket by pulling it from the upper funnel groove and lift out the existing filter plate. Clean the mating surfaces to remove coffee residues and scale. Fit a new rubber gasket into the funnel groove ensuring it sits evenly, then place the replacement metal filter plate back in its position. Reassemble the unit, tighten by hand until snug, and perform a test brew to confirm there are no leaks and that normal pressure and flow are restored.

Usage recommendations

If the original gasket shows hardening, cracks or compression set, replace it promptly. Regularly inspect and replace the gasket and filter plate as part of routine maintenance—especially when you notice leaks, reduced crema or irregular flow. Wash parts by hand with warm water and mild detergent; avoid aggressive scouring agents. Store spare gaskets in a cool, dry place away from direct sunlight to preserve elasticity.
