CO2 12g cartridge that contains 0.80 gram silicone sprayed out along with the CO2 in a mixture, which sits on the seals and seeps into the fine cracks and fault lines created by the dehydrating effect that the CO2's low temperature has on the seals over time with repeated application. Useful as an easy and quick tool-free maintenance method on your seals as well as the moving parts throughout the gun's interior, but does not replace the need to deep-clean and hand lube your gun over longer periods of shooting
ASG recommends using one of these in place of your each 10th regular CO2 cartridge. These cartridges can also not over-lubricate your gun either
