OEM/ODM China Pneumatic Piston Seal Types - Piston Seals FM2 is a reciprocating seal for both bore and shaft applications – Yimai

The FM2 seal is a single acting seal consisting of a U shell and a V corrosion resistant spring.
Its contour shape is asymmetrical, and its sealing working lip has optimum short and thick characteristics, thus reducing friction and extending life.
The metal spring provides the initial sealing force at low and zero pressure. When the system pressure rises, the main sealing force is formed by the system pressure, so as to ensure reliable sealing from zero pressure to high pressure.
Due to the excellent adaptability of seals and springs to appropriate materials, the FM2 seal can be used in general hydraulic systems, as well as in a wide range of other industries such as chemical, pharmaceutical and food.

FM2 type seal in order to disinfect it, and provides a “clean” seal, the spring at the cavity filled with silica gel, to prevent pollutants into it, it can also work in mud, suspension or binder and other media, can prevent sand into the seal chamber affect the spring work.
