Frequently Asked Questions

What is a blind gasket used for?

A blind gasket is a solid disc with no centre hole, used during backflushing to block the portafilter basket outlet so that cleaning solution is forced back through the group head solenoid and internal pathways. A worn or cracked blind gasket will fail to seal properly during backflushing, reducing its effectiveness.

Is this also the steam tap seal?

Yes — on the Carimali Nimble and Pratica, this ø12×5.8mm silicone gasket is also used as the steam tap seal. If steam is leaking from the tap base when the wand is closed, this seal is the likely cause.

Why silicone rather than rubber?

Silicone gaskets are more heat-resistant than standard rubber and maintain their elasticity at high steam temperatures for longer, reducing the frequency of replacement. They are the preferred OEM specification for steam-side seals.
