Engineered Solutions for the Bus and Transit Industry
Flexible Exhaust Couplings and Stainless Steel Exhaust Bellows
Our flexible exhaust couplings and stainless-steel bellows are engineered for bus OEM’s and transit fleets across North America. Designed for city buses, motor coaches, shuttle fleets, and hybrid vehicles, they absorb vibration, manage thermal expansion, and reduce stress on the exhaust system in high-temperature, stop-and-go conditions.
Manufactured from multi-ply stainless steel, they deliver high fatigue strength, corrosion resistance, and long service life. Optional external braid and internal liner configurations improve pressure capacity, exhaust flow, and durability — supporting OEM production, aftermarket replacement, and long-term fleet maintenance programs.

Silicone Hoses designed for O.A.T. Coolants
Transit buses operate in demanding, stop-and-go environments with constant heat, vibration, and heavy passenger loads. The best silicone hoses must deliver consistent cooling performance, structural integrity, and long service life under these conditions.
Our 4-ply aramid-reinforced silicone coolant hoses are engineered for bus OEM production and fleet maintenance programs across North America. Designed for city buses, motor coaches, shuttle fleets, and hybrid platforms, they provide high burst strength, long-term flexibility, and excellent resistance to heat aging and pressure cycling, ensuring dependable performance over time.
Fully compatible with O.A.T. coolants and rated from -65°F to 500°F (-54°C to 260°C), these hoses support reliable operation in extreme temperatures. Available in sizes from 0.50” to 6.00” ID, they facilitate smooth installation for both new vehicle assembly and aftermarket replacement, helping fleets reduce downtime and extend vehicle service life.

Air Conditioning Hose Assemblies
We design and manufacture metal air conditioning hose assemblies specifically for bus and transit HVAC systems. These non-permeable, all-metal assemblies are engineered to handle refrigerant service in high-vibration, high-cycle operating environments typical of city buses and motor coaches.
Constructed to isolate vibration and accommodate thermal expansion, our A/C hose assemblies reduce stress transfer among compressors, condensers, and evaporator units. Their metallic construction eliminates permeation concerns common with conventional rubber refrigerant hoses, helping maintain system pressure integrity and long-term refrigerant containment.
Designed for continuous duty transit applications, these assemblies withstand temperature fluctuations, pressure cycling, and road-induced vibration while supporting both OEM integration and aftermarket HVAC replacement programs.

Direct Fit Exhaust Assemblies
We supply direct-fit exhaust systems for bus OEMs and transit fleet maintenance programs across North America. Manufactured to original platform specifications, our assemblies ensure precise fitment, long service life, and reliable performance in high-mileage, stop-and-go transit operations.
Designed for EPA- and CARB-compliant buses, our exhaust systems seamlessly integrate with DPF and SCR after-treatment components used in modern diesel, CNG, and alternative-fuel transit vehicles, ensuring compliance and performance.
Available in aluminized steel and stainless steel (T304, T321, T409), our heavy-duty transit exhaust assemblies are engineered for corrosion resistance, thermal stability, and reduced downtime.
OEM production support. Aftermarket replacement solutions. Built for compliance and fleet uptime.

Thermal Shielding and Insulation Blankets
Our multi-layer metallic heat shields are fabricated from dimpled stainless steel, aluminized steel, or aluminum to manage radiant and conductive heat in transit, exhaust, and engine systems. The dimpled construction creates an insulating air gap that improves thermal dissipation while maintaining structural rigidity in high-vibration environments. Assemblies are engineered to withstand continuous temperatures up to 1200°C (2200°F).
Our removable insulation blankets are constructed with high-temperature core materials and reinforced outer jacketing to provide thermal containment and acoustic attenuation for exhaust manifolds, turbochargers, DPF/SCR after treatment systems, and engine compartments. Designed for pressure cycling, thermal expansion, and road-induced vibration, each blanket is custom-fabricated to meet OEM specifications or direct-fit aftermarket requirements for bus and transit fleets.
