At Signal Industrial Products, we pride ourselves on offering a wide range of engineered sealing solutions services to cater to the diverse needs of our clients.

Knowledge and Sourcing

We stay up-to-date with the latest advancements, industry trends, and best practices to provide our clients with accurate information and guidance when it comes to sealing solutions. We have established strong relationships with reputable manufacturers and suppliers, enabling us to source high-quality sealing components and materials efficiently.

Factory and Manufacturer Assistance
We understand that each sealing application is unique, and sometimes off-the-shelf solutions may not suffice. In such cases, our team can collaborate with factories and manufacturers to develop customized sealing solutions tailored to your specific requirements.
Application Engineering
Our skilled application engineers work closely with clients to analyze their sealing needs and challenges. By understanding the operational conditions, environmental factors, and performance expectations, we can recommend the most suitable sealing solutions for each application.
Inventory Management
We work closely with clients to develop tailored solutions that ensure the availability of essential sealing components when needed. This includes implementing inventory tracking systems, just-in-time deliveries, and proactive monitoring to anticipate and prevent potential shortages.
Custom Seals
Our experienced team will work with you to recommend custom seals that precisely fit your equipment, machinery, or systems. Whether it’s a unique shape, size, or material requirement, we leverage our experience and resources to deliver seals that offer optimal performance and reliability.
Custom Gaskets
We offer custom gasket solutions tailored to your specific application. Our team considers factors such as temperature, pressure, chemical compatibility, and flange specifications to make the best recommendations to provide an effective seal, reducing the risk of leaks and ensuring operational efficiency.
Custom Kits
To streamline procurement and installation processes, we provide custom sealing kits that include a combination of seals, gaskets, and related components needed for specific applications. These kits are assembled and packaged according to your requirements, allowing for easy identification, inventory management, and efficient maintenance.
These circular cross-section seals create a simple but reliable seal between two mating surfaces (typically with a machined groove), preventing leakage of fluids or gasses by mechanical deformation that creates a barrier to the leak path. Signal’s inventory of O-Rings are available in standard and custom sizes, ensuring a precise fit for different equipment and systems.
PTFE (Teflon®)
PTFE (Polytetrafluoroethylene), commonly known by the brand name Teflon®, is a high-performance material widely used in sealing applications. PTFE seals are suitable for demanding applications in industries such as chemical processing, food and beverage, pharmaceuticals, and more.
Machined Rubber and Plastics
We offer precision-machined rubber and plastic components that are tailored to meet specific sealing requirements. They are commonly employed in industries such as automotive, aerospace, electronics, and general manufacturing.
Molded Rubber Components
Molded rubber components are manufactured using high-quality materials, offering excellent resilience, durability, and resistance to various environmental factors. These components are designed to provide effective sealing, vibration isolation, and protection against contaminants.
These seals ensure efficient air compression, prevent leakage, and contribute to the reliable operation of pneumatic systems in industries such as automation, robotics, and manufacturing.
Mechanical Seals and Packing for Pumps and Valves

Standard Single Spring and Cartridge Mounted Seals are available for Process Equipment including Mixers, Agitators and Reactor Vessels. We work closely with manufacturers to correctly identify the application needed.

Fluid Handling
These products are engineered to withstand the specific requirements of fluid handling systems, including compatibility with various fluids, resistance to pressure and temperature, and prevention of contamination.
Rotary Seals
Rotary seals offer excellent sealing performance, low friction, and durability, ensuring reliable sealing in rotary applications such as pumps, motors, gearboxes, and rotary equipment.
Gaskets are essential sealing components used to create a reliable seal between two mating surfaces. They provide effective sealing against fluid and gas leaks, maintaining the integrity and safety of systems and equipment.
