Freudenberg O-rings

Freudenberg Sealing Technologies has been developing sealing technology for nearly a century. Headquartered in Weinheim, Germany, the company’s history in sealing dates back to the invention of the Simmerring® radial shaft seal in 1929. Today, Freudenberg is a global leader in sealing technology, with a broad portfolio of O-rings, radial shaft seals, hydraulic and pneumatic seals, and other sealing products used across industries worldwide.

Freudenberg is known for combining established sealing expertise with extensive material development, including proprietary compounds such as Simriz® perfluoroelastomers and AU 30000 polyurethane. Its broad product offering also gives customers options across different performance and price points, including cost-effective solutions for less demanding applications.

Why Freudenberg?

O-ring performance depends on much more than size alone. Material formulation, temperature, media compatibility, pressure, movement, and operating conditions can all influence how well a seal performs over time.

Freudenberg develops O-rings and elastomer materials for a broad range of sealing requirements, from standard industrial service to more demanding environments where chemical resistance, temperature capability, wear resistance, or regulatory requirements become especially important.

Its O-ring portfolio includes materials such as NBR, HNBR, EPDM, FKM, FFKM, silicone, polyurethane, and other specialized compounds. Freudenberg has also developed proprietary materials such as Simriz® perfluoroelastomers and high-performance polyurethane compounds designed for challenging sealing conditions.

Freudenberg O-rings are available in standard and specialized sizes, materials, durometers, and configurations for both static and dynamic sealing. Depending on the compound and product, options are also available to meet specific industry approvals and requirements.

Freudenberg complements its premium sealing portfolio with Dichtomatik products, providing customers with additional options for applications where dependable performance and cost efficiency are important.

The breadth of Freudenberg's material portfolio, combined with decades of sealing knowledge and product development, has made the company a trusted sealing manufacturer across industries worldwide.
