2.5mm IO Restrictor (4923293002)

Astoria Espresso Machine Part 2.5mm IO Restrictor (4923293002) is a precision-engineered component designed to optimize the water flow within Astoria espresso machines, ensuring consistent extraction and superior coffee quality. Crafted from durable, high-grade materials, this restrictor is meticulously calibrated to maintain an exact 2.5mm orifice size that regulates the water pressure and volume passing through the internal system. This precise control helps baristas achieve the ideal infusion rate, allowing for balanced flavor profiles and a rich, aromatic espresso shot every time.

One of the key benefits of the 2.5mm IO restrictor is its role in enhancing machine longevity and performance. By regulating the internal water flow, it prevents excessive pressure build-up and reduces wear on other machine components such as pumps and valves. This part also minimizes the risk of channeling—the uneven water flow through the coffee puck—which can cause under-extraction or over-extraction issues, leading to inconsistent taste. The restrictor’s reliable functioning contributes to maintaining the machine’s optimal operation, resulting in fewer maintenance interventions and downtime.

Designed specifically for use with Astoria espresso machines, this restrictor is an essential replacement part for cafés, restaurants, and coffee enthusiasts committed to excellence in every cup. Whether used during routine maintenance or as part of a repair strategy, the 2.5mm IO restrictor ensures that your Astoria machine performs at its peak daily. Available through Kaldi.com, this component supports your brewing precision and helps you deliver exceptional espresso experiences to your customers or guests, maintaining the high standards synonymous with Astoria craftsmanship.
