What a flat EPDM gasket is
This is a flat gasket made of EPDM rubber, used in the coffee machine to seal joints between metal and plastic parts – for example in the water supply, steam line, or milk system. Its purpose is to prevent liquid or steam from leaking at the point where two parts connect.
Signs of wear
EPDM rubber loses elasticity over time, hardening or cracking, especially with repeated exposure to heat and pressure. A worn gasket shows itself through dripping or leaking water or steam around the joint, hissing during brewing, or a drop in system pressure.
Why timely replacement pays off
A leaking joint increases water and energy consumption, can cause damage to surrounding parts from moisture, and in some cases leads to error messages on the coffee machine. Replacing the gasket is a simple and inexpensive fix that prevents bigger repairs.
How to choose the right gasket
- Check the dimensions of the original gasket before ordering
- Verify compatibility in the product's compatibility table
- When installing, do not lubricate the gasket with aggressive agents that could damage the rubber
