Quickfill adaptor with foster male for filling up your spare FX air bottle without losing air!

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.

Fill up your spare FX air tank the same way you normally fill your FX rifle with your large refill tank and fill set. 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 refill tank and depressurize the fillset and hose and you are ready. The quickfill adaptor can be unscrewed on and off the bottle without losing any air.

The quickfill adaptor for FX bottle's is also equipped with a M4 of M6 threaded hole where a headless M4 or M6 allen bolt can be screwed in, this can be used to open up the bottle's valve so you can depressurize a bottle or you can use it as a flow restrictor when filling the bottle so you will be sure the filling process will go slowly.

It is suitable for all FX cylinders like the 300 cc, 480 cc, 580 cc and the Dreamline compact air cylinder.

*Bottle is not included


NOTE:

Inside the FX valve construction there a 4.5 x 1.5 o-ring used. This ring is the only part keeping the valve seat in it's correct position. Due to the blast of air, in some occasions, this o-ring can be dislocated causing the valve seat not to close properly. This problem can be solved, or prevented, by following the instructions below:

Replace the red marked factory o-ring (see below) with the new o-ring (which has a different size and hardness). Huma-air includes this new model of o-ring with their FX bottle quickfill adaptors. The size used is 5.5×1.5 FKM.
