Airsoft Innovations Duster Adaptor.  Computer duster gas (compressed gas) can be used to fill Japanese guns (e.g., Tokyo Marui, Maruzen, Tanaka).  Duster gas is not intended for use with non-Japanese gas guns which use a higher pressure gas (propane).  However, this adaptor can be used as a replacement tip for the adaptor that comes with the “Airsoft Innovations Gun Gas Kit” or an earlier version of their propane adaptors that did not include a duster adaptor.  It can also be used as an extension for those mags that require an extra long fill tip.

To use this adaptor, just place two drops of silicone oil (not included) in the tip of the can of duster gas before attaching the adaptor.  Flip the can upside down and use it like you would a can of green gas!  Its that easy!  You are good to go for that mag’s next ten refills before you need to add more silicone oil.  The silicone oil is used to combat the drying effect that the compressed air will have on the rubber components—namely, the valves’ o-rings and hop-up.
