A gas refill valve functioned as a component within a blaster. Its purpose was to enable the replenishment of the blaster with various types of blaster gases. To suit the diverse array of blaster models, the nozzle of the gas refill valve was manufactured in a range of sizes and configurations. The gas was able to flow into the blaster via the gas refill valve, where it was then held within the internal gas chamber. These valves were frequently positioned at the rear of the blaster, a design seen in weapons like the DL-44 heavy blaster pistol and the DH-17 blaster pistol.
