DISCONTINUED I.4731 Portafilter Gasket Ascaso

I.4731 Portafilter Gasket for Ascaso Dream/PID 2019 and Steel Models

The I.4731 Portafilter Gasket is a replacement group head gasket designed for Ascaso Dream/PID 2019 and Ascaso Steel espresso machines. Measuring approximately 73 x 57 x 7.8 mm, this gasket features three internal cuts that help provide a secure seal between the portafilter and brew group.

A properly fitted portafilter gasket helps prevent water and pressure from escaping around the portafilter during brewing, supporting consistent espresso extraction and reducing leaks. This gasket is an excellent choice when an original gasket has become worn, hardened, flattened, or damaged.

When to Replace Your Portafilter Gasket

A worn group head gasket can cause portafilter leaks, reduced brewing pressure, difficulty locking in the portafilter, or water escaping around the group head. Replacing the gasket is a simple maintenance procedure that can help restore a proper brew group seal and maintain reliable espresso machine performance.

Important: Always verify the gasket dimensions, internal-cut design, and machine model before ordering to ensure proper fit.
