54mm Silicone Steam Ring, 2 Packs Grouphead Gasket Replacement Parts for Breville Replacement Parts, No BPA Silicone Gasket Breville Accessories fit with Sage/Breville Espresso Machine 450/870/878/880

The grouphead gasket is compatible with Breville 870/878/880/860/840/810/450/500 Sage 500/810/870/875/878/880 coffee machine models.

The 54mm espresso gaskets for Breville Espresso parts prevents steam or hot water from leaking out of the portafilter holder assembly and the thermal block assembly, ensuring the safe operation and use of the machine.

Food-grade silicone makes it suitable for long-term use without damage or deformation.

A spare steam ring is essential for prompt replacement and to prevent disruption to machine operation.

The silicone steam ring has good sealing performance, which can ensure the normal flow of water in the machine and prevent the water flow from bypassing the brewing head, leading to poor coffee flavor.
