Autopilot CO2 Generator Brass Plug

The Autopilot CO2 Generator Brass Plug is a replacement part for Autopilot CO2 generators. It is designed to seal unused burner outlets on generators that run on natural gas or propane, creating a reliable and secure connection. When a grower wants to reduce the number of active outlets on a multi-burner CO2 generator, this plug provides the correct fitting to do so safely. SKU: APCGBP.

Why Choose the Autopilot CO2 Generator Brass Plug

CO2 generators often come configured with multiple burner outlets to allow output scaling across larger grow spaces. When operating in a smaller room or using fewer burners, unused outlets need to be properly sealed to prevent gas leaks and maintain safe operating pressure. The Autopilot Brass Plug is designed specifically for this task.

• Dual-fuel compatibility: Works with both natural gas and propane CO2 generators, so it fits across the Autopilot generator lineup regardless of fuel source.
• Brass construction: Brass is standard for gas fittings because it resists corrosion and forms reliable seals under pressure. This plug uses the same material specification as the generator’s original fittings.
• Secure outlet closure: Creates a reliable and secure connection at unused burner ports, which is required for safe generator operation when running fewer than the maximum number of burners.
• Correct outlet-reduction procedure: The manufacturer specifies that when reducing outlets, growers should start from the back row forward. This plug supports that procedure by providing a correctly sized brass fitting for each outlet being closed off.
• Direct OEM replacement: Sold under the Autopilot part number APCGBP, this is the manufacturer-designated plug for Autopilot CO2 generators rather than a generic aftermarket fitting.

Best Uses for the Autopilot CO2 Generator Brass Plug

This plug is a purpose-specific accessory for CO2 generator maintenance and configuration. It is not a general-purpose fitting. Below are the scenarios where it applies:

• Reducing active burner count: When a grower wants to run a CO2 generator with fewer than its maximum number of burners — for example, in a smaller room or during early veg stages with lower CO2 demand — unused outlets must be plugged. This brass plug seals those ports correctly.
• Replacing a lost or damaged outlet plug: The original brass plug that ships with an Autopilot CO2 generator can be lost during maintenance or damaged over time. This part restores the generator to its complete configuration.
• Configuring a generator for propane vs. natural gas setups: Because the plug works with both fuel types, it can be used in any Autopilot generator configuration regardless of whether the installation uses propane tanks or natural gas lines.
• Indoor grow rooms and greenhouses: CO2 enrichment is common in sealed or semi-sealed indoor growing environments. This plug is a maintenance component for the CO2 burner generators commonly used in those setups.
• Commercial and hobbyist growers alike: Whether maintaining a single generator in a home grow tent or managing a bank of generators in a commercial facility, having the correct replacement plug ensures generators can be reconfigured safely when needed.

If you are managing other climate variables in your grow room, the Autopilot PX2 Advanced Lighting Controller integrates lighting schedules with environmental timing, and the Ideal-Air Pro Series dehumidifier replacement condensate pump supports humidity management in sealed environments.

Compatibility

The Autopilot CO2 Generator Brass Plug (APCGBP) is compatible with Autopilot CO2 generators that use standard threaded brass outlet fittings. The canonical product data confirms compatibility with both natural gas and propane generator models.

Key compatibility notes:

• Natural gas CO2 generators: This plug fits the outlet ports on Autopilot generators plumbed to natural gas supply lines.
• Propane CO2 generators: Also fits Autopilot generators using propane as the fuel source. No modification is required between fuel types.
• Outlet reduction procedure: Per manufacturer documentation, when reducing the number of active outlets on a CO2 generator, plugs should be installed starting from the back row forward. This ensures correct gas flow distribution through the remaining active burners.
• Not for non-Autopilot generators: While brass fittings are a common standard, this plug is listed specifically for Autopilot generators. Thread pitch and port diameter compatibility with other brands’ generators is not documented in the available product data.

Manufacturer-published compatibility data for specific model numbers is not included in the available product records. Consult autopilotcontrollers.com or the documentation included with your CO2 generator to verify fitment for your specific model.
