Charge Block Spring Ø 9.5×8.4×25mm

This precision spring is designed for the charge block assembly in Promac and Rancilio espresso machines. If your machine is losing pressure during extraction or the pump is cycling irregularly, a worn or weakened charge block spring is often the cause. Replacing this small but critical component restores proper water delivery and consistent brewing pressure.

This spring is manufactured to exact dimensions—outer diameter 9.5mm, wire diameter 8.4mm, length 25mm—ensuring proper compression and tension in the charge block mechanism.
