Stainless steel quickfill adaptor with foster male connection, to fill up your spare FX pressure bottle without losing any air when screwing it on- or off the bottle!

This solid, stainless steel, quickfill adaptor with foster male connection can be used to fill up your spare FX air tanks. The special design makes sure you do not waste any air when the adaptor is screwed on- or off the bottle so you always keep the maximum pressure left in the bottle.

The same way you normally fill your FX rifle, with your scuba tank and fill set, you can fill up your spare FX air tank. Just screw the adaptor into the bottle, connect your fill set with hose to the adaptor and fill up the bottle slowly to the maximum allowed fill pressure, close your scuba tank and depressurize the fill set and hose and you are ready. The quickfill adaptor can be unscrewed on- and off the bottle without losing any air.

The adaptor is also equipped with an M4 or M6 threaded hole where a headless M4 or M6 allen bolt can be screwed in — this can be used to open the bottle's valve to depressurize it, or as a flow restrictor to slow the filling process.

Suitable for all FX cylinders including the 300cc, 480cc, 580cc, and Dreamline compact air cylinder.

Machined from one massive piece of stainless steel for maximum durability and safety at up to 300 bar.

Note: Bottle is not included. Includes a replacement o-ring for the FX bottle valve seat (5.5x1.5 FKM).
