About Mechanical seal type 606
The Type 606 is a high-temperature (to 425°C/800°F) rotating seal with the same high-strength design features as the Type 609. In addition, the Type 606 incorporates drive lugs under the bellows that provide added rotational drive. This reduces torsional stress on the bellows, and makes the Type 606 the ideal seal for maximum reliability and extended life in viscous or thermosetting applications.
