Single Cartridge O-ring Seal

Designed to Reduce Installation Time and Errors

The compactness of the FFET cartridge seal ensures that it will fit all ANSI and DIN stuffing boxes and offers an ideal upgrade from packing. The FFET is a robust cartridge seal used for a variety of duties from chemicals to oil and water, and for many abrasive and crystallizing duties. It is ideal for use on top-entry mixers, where the liquid product may not provide continuous cooling and lubrication of the seal faces. The use of premium seal face materials ensures low heat generation and dry-running thermal stability. On top-entry agitators a design variation is available for use on hygienic applications.
