Roll Over Valve - 12AN ORB to 8AN Male

Radium Engineering vent valves feature roll-over protection for fuel cells and gas tanks. The valves come in different varieties for all fill type applications; standard fill and quick-fill. Simply put, the larger the vent, the quicker the fuel cell can be filled. NOTE: Be sure to lubricate the FKM O-ring prior to installing either valve.

STANDARD FILL ROLL OVER VALVE

20-0934 ROLL OVER VALVE, 12AN ORB TO 8AN MALE
This roll over vent valve can be used for fuel tanks that have -12AN ORB female threads. The large external -8AN male fitting is more than enough for all standard fuel filling. The 1-piece machined part is manufactured from billet 6061 aluminum and type-II anodized. Included is 1 ball valve, FKM O-ring, and a stainless steel retaining ring.

In case of an inverted accident in which the wheels are up-ended, the ball valve sinks sealing the vent. This safely prevents fuel from leaking out of the fuel cell vent line.

NOTES: 
1. The vertical height of at least one portion of the vent tubing (not included) should be positioned above the highest point of the fuel fill point. 
2. The valve can easily be disassembled for cleaning, inspection, and maintenance.
3. The valve is compatible with all fuel types including alcohol fuels such as methanol and E85.
4. This roll over valve comes standard on all Radium FCST units after August 2023.

FUEL LEVEL ADAPTER
20-0439 12AN ORB to 5-Bolt SAE Adapter
To use a Radium Engineering DSV on an old FCST that has 8AN ORB vent threads (20-014X-XX), this adapter can be used.

However, a fuel level sender cannot be used with this adapter in place.

REMOTE FITTING
14-0434 12AN ORB TO 12AN MALE
This would be used if the external quick fill DSV needs to be remotely mounted off the fuel cell. It will secure directly into the 12AN ORB Vent Port on the Radium FCST.

Or it can be used in conjunction with 20-0439 12AN ORB to 5-Bolt SAE Adapter for older FCST units.
