Precision sealing
for Freight trains
Your Rolling Stock Must Remain Protected Throughout the Journey
Freight trains operate in demanding environments, exposed to weather conditions, continuous track-induced vibration, and wide temperature variations across different regions. Poorly specified sealing solutions can allow moisture ingress into onboard equipment, accelerating electrical contact corrosion and reducing service life.
Maintaining reliable sealing performance throughout the entire journey is therefore essential to protecting critical systems and ensuring long-term operational reliability.

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 freight wagons continuously exposed to track irregularities.
We also offer four-lobe seals, whose geometry provides improved friction performance compared with conventional circular cross-section seals.
Extruded Profiles and Cellular Foams
Our extruded profiles provide acoustic sealing, pressure sealing, or fluid sealing, depending on the requirements of your rolling stock application.
Our range of EPDM cellular foam solutions complements this offering by delivering both thermal and acoustic insulation for freight wagons and railway equipment. Together, these solutions address all critical sealing points across your vehicles, from cable entry systems to the areas most exposed to environmental conditions.
