Gaggia Classic Pro OPV Spring – 9 Bar

Works ONLY on the Gaggia Classic PRO/ EVO and Gaggia Espresso Evolution.

The spring in your standard Gaggia espresso machine is a 12 bar spring.

This is because the machine is shipped with a pressurised basket.

If you are wanting to use a normal basket or any precision basket you want to remove the original spring and replace it with the industry standard 9 bar spring.

Works ONLY on the Gaggia Classic PRO/ EVO and Gaggia Espresso Evolution.
