The lever-locking mechanism prevents accidental valve openings with any engine vibrations, which is a critical key of our invention and manufacturing.
For added valve security we do offer lever clips now included with every F-type valve, for those rare events of debris contact with the lever at high speeds or extreme conditions.
FOR USERS OPERATING VEHICLES IN EXTREME CONDITIONS (ie. logging, off-road, farming), we recommend installing a lever clip or metal lever lock (compatible with T- and FG-valves). A lever clip/lock firmly secures the lever in the locked position at all times and prevents accidental openings in the toughest of conditions.
