Micro Seals: Precision and Reliability in the Smallest of Formats (For Modern Medical and Laboratory Technology)
Micro Seals stand for precision and reliability and are of crucial importance in modern medical and laboratory technology. These tiny, extremely precise components prevent leaks and ensure that devices function reliably and efficiently. They are used primarily in fluid handling valves, pumps and mixers, as well as small electric motors.
Freudenberg Sealing Technologies offers a broad range of micro-seals and components that are specially designed for the most demanding applications and manufactured in Germany. We have years of experience in the development and production of customized micro seals with dimensions of up to about 20 mm. Our extensive materials expertise, combined with our experience in the production of advanced tools and our in-depth knowledge of the manufacturing processes, make us a leading supplier of reliable micro seals.

Micro Seals – Maximum Variety in the Smallest Format
Our micro seals are developed specifically for each customer and their respective application. Every component is the result of close collaboration with our customers to overcome their specific challenges and requirements. The components presented here are therefore only examples of the countless possibilities for using our high-precision sealing elements and components in a wide variety of devices and systems to ensure maximum accuracy and reliability.
Customized micro seals: Versatile solutions for demanding applications
Micro-Simmerring®
It reliably seals rotating shafts of 1-3 mm at 20,000 rpm, withstands extreme temperatures and media. It also minimizes friction and maintenance costs.
Rocker Valves
They precisely control liquid and gas flows in 2- and 3-way microfluidic valves.
Flipper Valve Seal
These high-precision seals made of FFKM/FKM for microfluid valves provide reliable sealing at 7 bar for up to 10 million switching cycles with minimal tolerances and burrs.
Brake and Seal Disc
Specially developed for sealing dental drills, the Brake & Seal Disc is not only a dental seal, but also stops their rotation at up to 350,000 rpm in the shortest possible time for safe dental treatment.
Hammer Seal
These sealing components provide static and dynamic sealing functions, are made of chemically resistant FFKM, can withstand up to 7 bar and over 50 million switching cycles in complex 2/2 and 3/2-way solenoid valves.
Valve seat seal
Valve seats for axial solenoid valves ensure reliable sealing and precise control of the medium. They prevent leakage and are crucial for safe operation in applications such as medical technology and industrial automation.
“Dogbone” Elastomer Composite Seal
Elastomer composite Seals in the shape of a dogbone are composite Seals made of stainless steel and rubber that are used in 2/3-way solenoid valves. They are produced over 500,000 times a year and are universally suitable for various media thanks to FFKM. Also used in 2/3-way solenoid valves, this seal offers a high degree of reliability and durability.
Valve Seal
They control gas flows in medical devices. In anesthesia machines, they play a key role in the function and control of the solenoid valve system, which regulates the flow of anesthetic gases.

Micro seals are extremely small, high-precision sealing elements used in devices and systems that require the utmost accuracy and reliability. These components can be made of elastomers or elastomer-based composite materials and are used in a wide range of applications, from medical devices and laboratory instruments to industrial applications. Their primary function is to seal fluids or gases while maintaining the integrity of the system.
Micro seals fulfill various sealing tasks:
- Dynamic Sealing Pads: These parts provide a movable seal suitable for applications such as rotating or reciprocating motion.
- Diaphragms (Diaphragm): They are used to create flexible but tight separating layers, which are required in valves or pumps, for example.
- Static Sealing Bead: These seals are designed for applications where a firm, unchanging seal is required.
Depending on the specific requirements, various materials can be used to manufacture these micro Seals, including:
- EPDM, FKM, FFKM
Elastomers with outstanding chemical resistance, high temperature resistance and excellent aging and ozone resistance. - Thermoplastics (e.g. PA6.6 GF, PEEK), metals (e.g. steel, aluminum)
High-performance materials that often serve as base materials for elastomer-based composite concepts to provide additional strength and durability.

Get Expert Advice Today Micro Seals + Unique Material Know-How = ❤️🔥
The unique material know-how of Freudenberg Sealing Technologies is the best basis for selecting the right material. Depending on the requirements, FKM, FFKM or EPDM are used, each of which offers special properties:
FKM
FKM has excellent resistance to oils, fuels, chemicals and high temperatures of up to 250°C.
FFKM
FFKM is characterized by extreme chemical resistance and temperature resistance up to 327°C, making it ideal for use in aggressive environments. FFKM also has excellent aging resistance and retains its mechanical properties even under long-term exposure to high temperatures and aggressive chemicals.
EPDM
EPDM, on the other hand, is particularly resistant to ozone, UV radiation, hot water and steam. It can be used in a wide temperature range from -50°C to +150°C, in which EPDM also has good resistance to aging.
