Precision sealing
for Passenger trains
Your Doors and Windows Must Remain Sealed to Protect Passenger Comfort
Passenger comfort and safety depend directly on the sealing performance of your doors and windows. Poorly engineered seals can allow drafts and water ingress, degrading the travel experience and creating noticeable thermal discomfort within the first minutes of a journey.
Wide temperature variations across different regions and operating conditions place additional demands on sealing systems throughout the life of the train.

Our Sealing Solutions
O-Rings and Specialized Sealing Rings
O-rings provide effective sealing for the majority of fixed interfaces throughout your rolling stock. We have developed the BS ring to deliver simultaneous resistance to pressure and vibration, a key advantage for trains continuously exposed to track-induced disturbances.
We also offer four-lobe seals, whose geometry provides improved friction performance compared with conventional circular cross-section seals.
Extruded Profiles for Doors and Windows
Our extruded profiles provide acoustic and pressure sealing for doors and windows, tailored to the specific requirements of your rolling stock.
Our range of EPDM cellular foam solutions complements this protection by delivering both thermal and acoustic insulation for passenger coaches. Together, these solutions address all critical sealing points, from door systems to the areas most exposed to environmental conditions.
Gangway Bellows
Our gangway bellows provide a fully sealed connection between adjacent rail cars, protecting passengers from external weather conditions while ensuring a comfortable transition between vehicles.
The floor remains level with the passenger compartment, facilitating access for wheelchair users, passengers with strollers, and travelers with reduced mobility.
This complete sealing solution helps maintain a comfortable circulation area between cars while protecting passengers from variations in weather, temperature, and external noise throughout the journey.
