Sought after fill adaptor for your new Rohm Twinmaster PCP, fitted with the Walther
Reservoir. Can be identified by not having an O-ring on the probe that is supplied with the gun.
Our units are now “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.
