🔧 Installation
Tools required: 10 mm wrench
Installation steps:
Make sure the machine is switched off, unplugged, and completely cool.
Access the OPV and remove the original spring.
Install the SICLab 7 Bar OPV Spring in its place.
Reassemble the OPV and tighten the fitting firmly, but do not overtighten.
Turn the machine on and carefully check the connection for water leaks.
Check the brewing pressure with a suitable pressure gauge after installation.
⚠️ Important: Do not overtighten the fitting. Excessive force can damage the threads or sealing components. After installation, always check that no water is leaking around the connection before using the machine normally.
☕ Compatibility
Designed for Gaggia Classic machines using the compatible OPV spring configuration.
Compatible with many Gaggia Classic generations, but please verify your machine's OPV configuration before ordering.
Important: The final brewing pressure depends on several factors, including the Gaggia Classic model, pump condition, OPV configuration, water flow, and other components in the hydraulic system. The spring is designed to target approximately 7 bar, not to guarantee an exact pressure on every machine.
📦 Production & Shipping
Made to order in Brașov, Romania.
Production time: 2–4 business days.

🧼 Care & Maintenance
The spring itself requires no special maintenance.
When servicing the OPV, inspect the valve and surrounding components for scale, coffee residue, or debris and clean them as necessary.
For consistent results, periodically check the actual brewing pressure rather than relying solely on the spring specification.
A Small Spring. A Different Pressure Profile.
