Innovative Sealing and Fluid Handling Solutions for Truck and Bus Applications

truck and busA proven partner serving the world’s leading truck and bus manufacturers for more than 50 years, Cooper Standard ISG is your one-stop shop for high-performing engineered sealing solutions, as well as advanced fluid handling systems that can help optimize new vehicle designs and stay far ahead of the market trends, especially as trucks and buses evolve to run on hydrogen, electric and other alternative fuels. 

Design and Development Expertise

In addition to industry-leading standard engineered solutions, Cooper Standard helps truck and bus manufacturers design and develop custom engineered sealing and fluid handling solutions from the ground up. Cooper Standard delivers world-class engineering expertise, supported by computerized tools such as Finite Element Analysis (FEA), that can predict seal performance in a virtual environment, and Computational Fluid Dynamics (CFD) to precisely fine-tune fluid handling systems flow before production. These capabilities help slash development costs and accelerate time to market.

Sealing Solutions that Meet Demanding Needs

Contemporary sealing technology emphasizes comfort, safety and performance for truck and bus applications. For example, Cooper Standard seals deliver tight tolerances throughout the cab, minimizing wind and road noise, eliminating water ingress and maintaining desirable temperatures and humidity, helping keep drivers reliably on the road for the long haul.  

Further, high-quality seals help optimize aerodynamics and operations even as traditional truck and bus configurations change, with designs that help account for the new sealing demands of revised door and mirror placements, onboard cameras, and evolving fueling systems.  

Meeting Compliance Challenges

We support our customers’ sustainability efforts with seal designs that optimize performance and help enable new power-train designs, as they evolve to meet certain regulatory demands like EPA, CARB and DOT. Cooper Standard ISG strategically designs our materials to help ensure that you are always on the right side of every regulation. 

Contact us for other regulations and sealing challenges, including lower-weight materials for better fuel economy, leaks or excess noise — we can help. Our engineers are expert troubleshooters and can help you solve the problem.

Advanced Materials Expertise for Maximum Performance 

Cooper Standard ISG compounds many of our own materials to deliver the highest quality and optimum mix of desired properties in the finished truck and bus components. We offer many levels of firmness in our vast library of materials. To learn more about our customized materials solutions, visit our materials page. Not sure if your application needs rubber or plastic? Check out our webpage about the difference between EPDM vs. Silicone, and explore the science behind the selection process. 

Our materials portfolio includes but is not limited to: 

EPDM

For optimum compression, price and overall performance, EPDM rubber is the go-to for dynamic sealing in truck and bus doors and windows. 

Silicone

Silicone is the go-to material for high- temperature applications, such as protecting the battery compartment in electric and hybrid trucks and buses from water, wind and road hazards. Learn more about our silicone-grade materials and capabilities or our custom silicone extrusions
