This Rollover Vent is properly manufactured with the correct 1/2" NPT Taper thread and is checked using a thread gauge.
Q: What is the Roll Over Safety Vent? Do i need it?
A: The Rollover Safety Vent is a simple ball check valve device that will allow the tank to vent when in the normal operating position and also act as a Anti-Splash when your tank is full. In the event of an accident causing a rollover the ball will drop and block off the vent port so that fuel does not leak out. For safety I would always recommend purchasing the Rollover Safety vent
