Sought after alternative fill adaptor for your FAS Pistol. Standard 1/8″BSP male thread allows direct fitting to a flexible fill line or one of our Quick Coupler Plugs.
Our units are “Through Drilled” to allow for conventional bleeding of the charging system without the need to partly unscrew the reservoir whilst still under pressure.
This helps to prevent premature wear of the reservoir threads and any subsequent damage from debris entering the gun.
