Actuation Options


Push connector on, rotate bail handle over valve for connection. No wrenches or twisting needed. The handles are available in many sizes to fit applications filling with: standard valves, RPV valves, valve guards, valves with integrated pressure regulators, and 6 or 12 packs.


Simply push on and pull off. Pressure locks the connector on during the fill process. Great for small medical applications filling valves with integrated pressure regulators.


The FasTest MediMate is the industry standard solution for filling small medical cylinders with post valves. Position the connector aligning the pins into the valve, then cam over the handle to connect.
