54mm Silicone Steam Ring Group Head Gasket Replacement Fits Breville Espresso Machines

Is your espresso machine now losing pressure, letting liquid drip from the portafilter as the espresso is extracted, or causing water to leak into your cup? The factory rubber gaskets eventually dry out, harden, and crack as a result of the heat and pressure.

This high-temperature silicone, which is 100% food grade, premium replacement steam wand creates a tight seal in order to restore maximum brewing pressure and get rid of group head leaks permanently.

🛠️ Quick & Easy 4-Step DIY Installation Guide

1. Safety first: switch off the espresso machine, unplug it from the outlet, and let the group head cool down completely.
2. Remove the old gasket: First take off the shower screen, then use a flathead screwdriver or a pick tool to carefully push the hardened rubber gasket out.
3. Clean the recess: Make sure you wipe the internal channel of the group head thoroughly in order to remove any buildup of coffee oil, grit, and old residue.
4. Install the new ring: Insert the new silicone gasket, then reattach the shower screen and tighten the screws firmly.

⚠️ Important tip when installing it: The flat side should be placed upwards (towards the machine) and the grooved side downwards (towards the portafilter).
