Milwaukee MA957 CO2 Flow Pressure Regulator with Solenoid Valve
Stable CO₂ is the difference between a planted tank that “survives” and one that truly thrives. The Milwaukee MA957 CO2 Adjustable Flow Pressure Regulator is a high-quality regulator built with standard brass fittings for long-lasting performance in aquarium and hydroponics applications. It includes an integrated solenoid valve so your CO₂ can be automated through a controller—helping you maintain consistent dosing and a healthier, more predictable planted tank.
Product Overview
The MA957 is designed to deliver controlled, adjustable CO₂ flow while providing the core features aquarists rely on for daily use: a solenoid, diaphragm valves, and a built-in bubble counter to help you dial in your bubble rate with confidence. It’s designed to be compatible with all Milwaukee controllers, including MC122 and MC125, making it a dependable choice for automated CO₂ systems.
Key Features:
- Built for reliability: High-quality construction with standard brass fittings designed for long-term use.
- Controller-ready automation: Integrated solenoid valve allows your Milwaukee controller to manage CO₂ on/off cycles.
- Fine-tuned CO₂ control: Adjustable flow helps you match CO₂ output to your tank size and plant demand.
- Built-in bubble counter: Makes it easier to set and monitor your CO₂ bubble rate at a glance.

Together, these features make the MA957 a practical, dependable foundation for consistent CO₂ injection.
How to Use & Specs
Install the MA957 on your CO₂ cylinder, connect 1/4" CO₂ tubing, and use the regulator controls to set a stable working output. Fill and use the bubble counter to dial in your bubble rate, then plug the solenoid into your compatible Milwaukee controller (or timer) so CO₂ can be automated around your lighting schedule. As with any CO₂ setup, leak-check connections and make small adjustments gradually.
