BJR Roll Over valves
Roll Over valves works by allowing air into the tank to displace the fuel being used, forcing air out of the tank due to thermal expansion, and forcing it closed to prevent fuel from escaping due to vehicle rollover. They are made from billet aluminum and are anodized to protect them. It has a ball bearing inside the lower half that allows air to breathe easily without any restrictions. However, if the tank is turned upside down, the ball bearings will drop to the top of the fitting, effectively cutting off the outlet. These bolt-on flip valves are designed to be installed into a fuel tank or battery as a bulkhead accessory.
Available in -6 to -16 AN fittings and comes with 2x PTFE gaskets for sealing.
