Additional Information for Preformed Packing Additional Information for Preformed Packing

Preformed packing refers to a type of sealing material that is pre-cut or pre-formed into specific shapes or sizes. It is commonly used in applications where a tight seal is required, such as in pumps, valves, and other mechanical equipment.

Preformed packing is typically made from materials such as rubber, graphite, PTFE (polytetrafluoroethylene), or other synthetic materials. These materials are chosen for their ability to withstand high temperatures, pressure, and chemical exposure.

The main purpose of preformed packing is to prevent leakage of fluids or gases from the equipment it is installed in. It provides a reliable and durable seal that helps maintain the integrity of the system.

When selecting preformed packing, it is important to consider factors such as the operating conditions (temperature, pressure, and chemical compatibility), the size and shape of the sealing area, and the specific requirements of the application.

In the supply group Hardware And Abrasives, preformed packing is categorized under the class Packing And Gasket Materials. This class includes various types of packing materials, gaskets, and sealing products used in industrial and mechanical applications.
