Freudenberg Sealing Technologies (FST) Automotive, a market leader in the auto industry’s technology, quality and service segments, offers a diverse portfolio of products to all the major automobile and commercial vehicle manufacturers worldwide. The portfolio includes a large assortment of seals ranging from our near frictionless dynamic seal, Levitex, to static sealing solutions suited for even the harshest conditions.
As battery, fuel cell, charging and hybrid technology emerge, so does the growth in our product offerings. To meet the demands of these new systems, FST is now prepared and ready ready to support solutions that extend outward from sealing. The electrification of the vehicle creates potential needs for electromagnetic interference shielding and pressure management. For this, we now offer a wide array of EMI shielding plastics and DIAvent®, respectively. The list of our innovations is constantly growing in the fields of battery, fuel cell, e-powertrain, power electronics, engines, transmissions, suspensions, steering systems, drivetrains, climate control, & conventional fuel systems.
All of this is made possible by our cutting-edge research, absolute perfection in manufacturing and outstanding customer service. We look forward to what we can create together!
The Future Begins Now
As an innovative partner to our customers, Freudenberg provides custom-engineered materials and technology expertise to resolve all of your E-Mobility challenges.
Our portfolio on components addressing thermal management, temperature and pressure control, power densities and service improve the safety, reliability and range of electric vehicles. Our DIAvent® component, for example, offers intelligent pressure management solutions for large batteries in electric and hybrid vehicles. Specially developed heat shields for lithium-ion battery systems prevent the heat from “propagating” to neighboring cells when cells malfunction. The patented nonwovens they contain reliably ensure bi-directional pressure compensation even under extreme conditions.

Hydrogen Fuel Cell Cars
Fuel Cell Stack Components and Housings
Low hydrogen permeation materials, water, safety, tolerance compensation in the stack, vertical integration (different Freudenberg components) are all different forms of competencies and value we bring to our customers. We work as a partner to help develop customized solutions together with our customers.
Freudenberg has been developing its expertise in the field of fuel cells since the 90s. We are known for the durability of our polymers that allow for different functions to be integrated. We support forklift trucks, commercial vehicles, buses, trucks, ships, trains, bikes and drones.
Applications in Which We Make Parts
O-rings
Please contact us for more information.
Tank Valve O-rings
(minus) 60 degree Celsius material specifically formulated and designed for hydrogen applications.
Back Up Rings
Please contact us for more information.
Stack sealing
Loose gaskets for prototypes, FCPO materials in stack sealing and other fuel cell stack gaskets.
Seal on bipolar plates
Seals on both metal and graphite bipolar plates are possible.
Seal on GDL
Seal on Freudenberg GDL.
Plug and Seals
Our well-established plug and seals are the perfect interconnection in cooling systems. Compared to competitive solutions, they are extremely resistant against vibration and possess excellent tolerance compensation. Furthermore, when an application requires it, a sensing function can be incorporated into this solution to offer even greater value.
Plug and Seals With Sensors
All the benefits of our conventional plug and seals, but enhanced with various sensing capabilities e.g. temperature.
DIAvent® Light
Similar to our DIAvent®, DIAvent® Light also provides pressure regulation during normal operation with extremely high gas permeation.
Port Seals
Port seals for water glycol/deionized water.
O-Rings
Tank valve o-rings for hydrogen applications.
DIAvent® Light
Similar to our DIAvent®, DIAvent® Light also provides pressure regulation during normal operation with extremely high gas permeation.
Sealing Disks
They open and close and regulate pressure through valves to offer high lifetime durability. Low hydrogen permeation prevents hydrogen embrittlement.
