Precision sealing
for Passenger Metro
Your Doors Open Hundreds of Times a Day in a Tunnel Environment
Metro doors open and close hundreds of times every day in tunnels where brake and rail dust remain suspended in the air and gradually accumulate on sealing systems. Every door seal must withstand these intensive operating cycles without compromising sealing performance. The challenge is further intensified by the confined environment, where humidity can build up in underground sections of the network.

Our Sealing Solutions
O-Rings and Specialized Sealing Rings
O-rings provide effective sealing for the majority of fixed interfaces throughout your rail systems. We have developed the BS ring to deliver simultaneous resistance to pressure and vibration, a key advantage for rolling stock subjected to continuous stop-and-go operation.
We also offer four-lobe seals, whose geometry provides improved friction characteristics compared with conventional circular cross-section seals.
Extruded Profiles for High-Cycle Doors
Our extruded sealing profiles provide both acoustic and pressure sealing for doors subjected to constant operation throughout the day.
Our range of EPDM cellular foam solutions complements this protection by combining acoustic insulation and thermal performance, making them particularly well suited to the confined conditions of underground rail networks.
This broad portfolio addresses all critical sealing points across your installation, from door systems to cable entry interfaces.
