Madbull XG02 Airsoft Propane Adapter with Silicone Oil Port – CNC Aluminum Build for High-Pressure Applications

Upgrade your gas-filling setup with the Madbull XG02 Airsoft Propane Adapter, a robust and reliable tool designed for serious airsoft enthusiasts and techs. Built to work with standard CO2 air tanks, this adapter lets you fill your airsoft magazines and devices with propane efficiently—while injecting silicone oil directly into the system for better internal lubrication and long-term maintenance.

Built for Strength and Precision

Constructed from CNC-machined high-grade aluminum, the Madbull XG02 is engineered to handle demanding field use. Its stainless steel CNC core ensures long-lasting durability and consistent performance, even under heavy-duty conditions. Whether you're filling gas grenades, airsoft shells, or CO2-compatible magazines, this adapter is ready to take on the job.

The serrated body gives you a solid grip, making it easy to twist the adapter on and off propane tanks—even with gloves or oily hands. The integrated rubber O-ring ensures a tight seal that helps prevent leaks, reducing wasted gas and ensuring efficient performance every time.

Integrated Silicone Oil Port – Lubrication Made Easy

What sets the Madbull XG02 apart from typical propane adapters is its built-in side oil port. This innovative feature allows you to add silicone oil directly into the gas stream, which then mixes with propane or CO2 as it enters your magazines. This helps keep your internal seals, valves, and O-rings lubricated during regular use, improving longevity and reducing wear on gas-powered guns and accessories.

Simply add a drop or two of silicone oil into the port before filling. The oil disperses with the gas, providing consistent internal protection with minimal effort.

💡 Note: Always use 100% pure silicone oil to avoid damage to seals and rubber parts.

For High-Pressure CO2-Compatible Devices Only

While this adapter is highly versatile, it is not regulated—meaning the gas output is at full CO2 pressure. As a result, it should only be used with devices specifically designed to handle high-pressure gas, such as CO2-compatible airsoft grenades, shower shells, or Madbull-compatible launchers.

DO NOT use the XG02 with green gas-only magazines, standard GBB pistols, or any components that are not rated for unregulated CO2 pressure. Doing so can cause catastrophic failure and injury.
