The SS680 is the ideal seal for general-purpose applications. Its rotating Alloy-20 bellows provide corrosion resistance in a broad range of corrosive media. Its cost-effective design, combined with a reliable performance history, has made the SS680 a standard for low-temperature applications found in the chemical, water and wastewater, pulp and paper, and utility industries. The seal is available with hard faces for abrasive applications and a wide range of elastomers to cover a broad range of applications.
