Quick Details

  • Place of Origin: United States
  • Brand Name: Emco
  • Model Number: A1100


This two-stage overfill prevention valve with internal float is designed for use with dual point & coaxial drop tubes

The A1100 is easily installed in a new or existing drop tube assembly for economical compliance with EPA regulations. Unlike competitive units, the A1100 features an internal float design that eliminates any chance of the floats getting caught on tank walls or the riser pipe. This design also prevents float damage during installation.

Stick gauging is never a problem due to the Emco Wheaton designed stick diverter and automatic spring loaded poppet that retracts from the flow path when not in operation. The A1100 is compatible with all standard fuels.
