Radium Engineering DSV Valve Extension Adapter

Radium Engineering  internal DSV valve can be used for fuel tanks that have -12AN ORB female threads (including the Radium FCST). The high flowing -12AN male fitting permits dry break applications that use dump cans for quick fuel filling. The 1-piece machined part is manufactured from billet 6061 aluminum and type-II anodized. Included are 2 ball valves, FKM O-ring, and a stainless steel retaining ring. These materials are compatible with all fuel types including alcohol fuels such as methanol and E85. It can easily be disassembled for quick cleaning, inspection, and maintenance. 
20-1035 DSV VALVE EXTENSION ADAPTER
When installed with a DSV, this extension adapter will effectively move the air shut-off point higher in the system.

This will efficiently speed the refueling process by preventing dump can chugging. Radium DSV valves are not included (20-0535 shown below left / 20-0935 shown below right).

NOTES
