Madbull XG02 Propane Adapter

The adapter features a dedicated side chamber where you add silicone oil. As you press the adapter onto your magazine to fill it with propane, the gas passes through this chamber, picking up a small amount of oil and distributing it directly into the magazine's internal seals.

This adapter is designed for standard gas blowback (GBB) magazines that use a propane fill valve. While it is compatible with most major airsoft brands, it will not work with magazines that use proprietary or non-standard fill valves.

You do not need to refill the oil chamber every single time. Simply keep the chamber topped off periodically, and the adapter will automatically mix the oil with the propane as needed, ensuring your seals stay lubricated without over-saturating the system.

No, the design includes a mechanism that prevents silicone leakage when the adapter is disconnected from the gas canister or magazine. It is safe to store in your gear bag without worrying about messy oil spills.

The stainless steel core provides the necessary structural integrity to handle the high pressure of propane canisters without deforming or stripping. It ensures a consistent, airtight seal during the filling process, which is critical for preventing gas waste.
