Steam Tap Seal SES990

What this seal does

The Steam Tap Seal SES990 is a small gasket fitted around the steam cock of a coffee machine. It creates a tight seal at the point where the steam tap connects to the housing, preventing steam and pressure from escaping during frothing or hot water dispensing.

Signs it needs replacing

Over time, this seal is exposed to repeated heat cycles and pressure, which causes it to harden, crack or lose its shape. Once worn, you may notice steam hissing or leaking around the tap, a drop in steam pressure, or moisture forming near the steam wand base. A worn seal can also make the steam tap feel loose or wobbly when turned.

Choosing the right part

Replacing the Steam Tap Seal SES990 promptly helps restore proper sealing and steam performance. Before ordering, check the compatibility table by the product to confirm it matches your specific coffee machine model.
