Gasket for pressure hose for Bosch Vero 3,8x1,5 mm coffee machines

What is the pressure hose seal

The pressure hose seal is located at the connection point of the hose that carries hot water under pressure to the brewing unit or outlet of the coffee machine. Its job is to seal the joint so that pressurized water does not leak outside the intended path and so the coffee machine reaches the pressure needed for coffee extraction.

When the part stops doing its job

An old or hardened seal loses its elasticity and no longer seals perfectly. This shows up as water or steam leaking around the hose, dripping under the machine, weaker or unstable pressure during brewing, and sometimes a pressure-related error message on the coffee machine. The machine may also make a hissing sound as water flows through.

Why timely replacement pays off

A leaking joint increases water consumption, can damage nearby components through moisture, and causes uneven extraction, which affects the taste of the coffee. Replacing the seal is a simple and inexpensive fix that prevents bigger failures in the hose system.

How to choose the right seal

• Check compatibility with your model in the product table.
• When replacing, also inspect the condition of the hose itself and the adjacent connections.
• Replace the seal in pairs if the joint uses more than one piece.
