Custom-Engineered Seals for Buses, Coaches, and Transit Vehicles

At FlexSeals (FS USA), we design and manufacture high-performance sealing solutions for the transportation industry that are built to meet the extreme demands required. From city buses and school buses to commercial coaches and fleet vehicles, our seals provide reliable protection against air, water, dust, and vibration, improving durability, safety, and passenger comfort.

Transit vehicles operate under challenging conditions, with constant vibration, fluctuating temperatures, and heavy daily use. Our U.S.-made custom seals are engineered to endure these environments while maintaining consistent performance.

Engineered for Transit Applications
We supply a full range of extruded and trim sealing profiles that address the unique sealing needs of transportation manufacturers and fleet operators. Common applications include:
  • Entry and emergency exit doors
  • Windows and ventilation openings
  • Hatches and roof panels
  • Access doors and service compartments
  • Interior paneling and trim seals
Every FlexSeals product is built to integrate seamlessly into vehicle assemblies, reducing wind noise, preventing leaks, and enhancing thermal efficiency.

Materials Built for Harsh Environments

Our seals are manufactured using durable, transportation-grade materials including:
  • EPDM Rubber: Excellent resistance to UV, ozone, and weather extremes
  • PVC: Lightweight and cost-effective for interior and trim applications
  • Dual-Durometer Compounds: Provide flexible sealing with rigid attachment
With options like sponge, dense rubber, top bulb, side bulb, and edge trim profiles, we tailor every seal to match your precise performance and installation needs.
Solving Industry Pain Points

One of the most common challenges in bus and coach manufacturing is premature seal failure. Leaks, rattles, and air gaps can lead to customer complaints, warranty claims, and high maintenance costs. Our precision-engineered custom seals maintain their shape, resist compression set, and stay effective even after thousands of open-close cycles.

By partnering with FlexSeals, OEMs and fleet operators reduce downtime, lower costs, and enhance vehicle reliability across the board.
