Tank car fittings

Top fittings on tank cars may vary in design and position. NorFalco cars have either conventional acid car top fittings or a new, low-profile design.

Low-Profile Top Fittings

For more information, please do not hesitate to contact your NorFalco representative.

Conventional Top Fittings include:

A hinged fill hole and cover with a gasket seal.
A 3" discharge (eduction pipe) closed with a pipe cap.
A 1" air connection and pressure release valve.
A safety vent assembly containing a rupture disc to protect the tank from excessive pressure (typically adjacent to fill hole). A surge arrestor or hydro damp under the safety vent assembly reduces the internal surge pressures at the safety relief device interface.
A gauge bar mounted inside the fill hole nozzle to gauge level when loading car.
Please note that on some of the NorFalco tank cars, pressure relief valves (PRV) are installed. Such assembly are equipped with a spring loaded mechanism that would open in the event of high pressure and are not equipped with rupture disc.
