The vacuum breaker is installed on cargo tank trailers to allow atmospheric air into the tank during unloading, preventing dangerous vacuum conditions that could collapse the tank. Over time, the poppet's seal or spring mechanism may wear out, causing improper venting; replacing this poppet restores the breaker's safety function.
