Exactseal produces custom door seals, window-glazing profiles, gaskets, and O-rings for rail cars, subways, light rail, and transit buses. Our components handle constant vibration, high-cycle passenger doors, HVAC sealing, and exposure to weather, grime, and aggressive cleaning chemicals. We manufacture extruded and molded parts to your specification, sealing vestibules, coupler covers, floor pans, and battery compartments for reliable service across millions of revenue miles.

We compound EPDM, silicone, neoprene, nitrile, and Viton/FKM from 30 to 90 Shore A durometer, with low-smoke and flame-resistant options for rolling stock. Our mass transit seals hold RMA tolerances under an ISO 9001 and IATF 16949 quality system. Request a quote for your program.
