4L HHO Reservoir – Durable, Heat-Resistant & Easy to Install

Upgrade your HHO system with our 4-liter HHO Reservoir, specifically designed to support all HHO dry cell kits for cars and vans. Built in Europe with top-grade Polyethylene High Density (PEHD), this reservoir resists heat and delivers long-term reliability, even in demanding engine environments.

We engineered this HHO Reservoir with mounting ears to make installation fast and easy on any light vehicle worldwide. The tank arrives uncut—without pre-drilled holes or connectors—so you can fully customize it based on your setup. Its thick PEHD walls allow you to create precise threads for your hose fittings without needing glue. Glues can’t hold up against NaOH or KOH-based electrolytes, but our reservoir is built to handle them without compromise.

The front has a flat surface that is perfect for mounting a water level indicator. Connect a buzzer or diode to monitor electrolyte levels easily and prevent downtime during operation.

We chose the 4L size based on years of hands-on experience—it fits perfectly in most vehicle installations while holding enough water for extended HHO usage. The polyamide cap features an EPDM rubber gasket, ensuring a 100% leak-proof seal from liquid and HHO gas.

If you’re in the HHO business or building your kit, this HHO Reservoir is a must-have component.
