drukring

Drukring is a Dutch term that literally means “pressure ring.” In technical usage it refers to a ring-shaped component that is designed to create, transmit, or maintain pressure in a system, or to provide sealing between mating parts. The exact meaning of the term varies by industry and context.

In mechanical engineering and hydraulics, a drukring typically sits between components such as a piston and housing or a gland and shaft. Its functions can include distributing axial load, stabilizing position, and assisting sealing. Materials range from metals (such as steel or stainless steel) to high-strength polymers, and geometries are usually annular or stepped. The drukring is often used in conjunction with gaskets, packing rings, or O-rings and must be selected for the operating pressure, temperature, and chemical environment.

In other contexts, the term can appear in the printing industry or in vendor-specific documentation to denote a ring used to apply or set pressure in a press or assembly. Because meanings can differ, it is important to rely on accompanying specifications or drawings to determine the exact function and dimensions of a drukring in a given application.
