Stirring Assembly SS PTFE Lined

Stirring Assembly SS PTFE Lined

The Stirring Assembly SS PTFE Lined is a chemically resistant agitation system designed for glass reactors handling corrosive, aggressive, or high-purity media. By combining the mechanical strength of stainless steel with the inertness of PTFE lining, this assembly ensures safe, contamination-free, and long-term operation.

This stirring assembly features an SS core shaft and housing fully lined with PTFE, preventing direct contact between the process fluid and metal components. It is ideal for processes where chemical compatibility, product purity, and corrosion resistance are critical.

The design supports smooth torque transmission while maintaining leak-tight performance during continuous or batch agitation.
