Astoria Group Undercup Seal 66x56x5.5 (Part Number 12216) is a precision-engineered replacement component designed specifically for Astoria espresso machines. Crafted from high-quality, durable rubber material, this seal ensures a tight, leak-proof fit between the group head and the undercup, preventing water and steam from escaping during the brewing process. Measuring 66mm in outer diameter, 56mm in inner diameter, and 5.5mm in thickness, this seal matches the exact specifications required for optimal performance and longevity within the machine’s group assembly.

One of the key features of the Astoria undercup seal is its superior resilience to heat, pressure, and chemical exposure. Espresso machines operate under intense conditions, with frequent exposure to hot water and steam as well as cleaning agents. This seal is specially formulated to maintain its elasticity and sealing properties even after prolonged use, thereby minimizing the risk of leaks that can diminish espresso quality or damage the machine. By providing a secure and consistent seal, it supports the machine's ability to maintain proper pressure levels, which is crucial to extracting rich, full-bodied espresso shots with ideal crema.

This part is an essential maintenance item for cafés, restaurants, and baristas relying on Astoria espresso machines for daily coffee production. Over time, seals can harden or degrade, leading to leaks or inefficient brewing cycles that affect both the taste and consistency of your espresso. Installing the Astoria Group Undercup Seal is a straightforward way to ensure your machine runs smoothly, reduces downtime, and extends the lifespan of your equipment. Available now at Kaldi.com, this genuine replacement part is a smart investment to keep your espresso machine operating at peak performance and delivering café-quality espresso shot after shot.
