O-rings are widely recognized as the most prevalent sealing component utilized in various industrial applications to prevent the leakage of fluids or gases. They find extensive use in hydraulic systems, pneumatic systems, and fluid power applications. Moreover, O-rings play a crucial role in industries such as aerospace, automotive, medical, oil, and gas, as well as chemical processing. At Signal Industrial Products, we maintain a strategic inventory of standard-size O-rings in commonly used materials such as Buna-N, FKM, FFKM, EPDM, PTFE, and Aflas. Additionally, we stock some of the more frequently required metric sizes.

However, we understand that specific applications may require specialized compounds. Therefore, we encourage you to consult with our specialists to determine the best compound suited for your unique requirements. We can provide vulcanized and custom-sized O-rings utilizing a wide range of different compounds. Additionally, we offer PTFE Encapsulated O-rings as part of our product range.

We provide a wide selection of standard gaskets, such as Ring, Full Face, and Teflon Envelope gaskets, as well as craft custom gaskets tailored to specific customer needs. Whether it’s unique dimensions, materials, or specialized designs, we have the capabilities to manufacture custom gaskets that precisely match the requirements of your application. 

We also offer U-Channel extrusions, which are versatile sealing solutions widely used in industrial applications. These extrusions provide effective sealing and protection against environmental factors while accommodating movement and compression. Alternatively, sponge strips provide excellent sealing properties that are ideal for applications requiring flexibility and conformability. These strips offer reliable sealing and cushioning in a variety of industrial settings.

In terms of production methods, we offer flexibility to meet diverse needs. Whether you require large volume orders or one-off gaskets, we employ various cutting techniques, including die cut, knife cut, water jet, lathe cut, and hand cut. We are dedicated to providing you with reliable sealing products that meet your specific requirements.

Pump packing, commonly made with PTFE or graphite materials, involves installing packing around the shaft to minimize leakage. It provides a reliable sealing method and has been widely used in various applications. However, it is important to note that mechanical seals offer more advanced engineering and enhanced performance compared to pump packing.

Mechanical seals are sophisticated sealing solutions designed with precision. They consist of stationary and rotating sealing faces, secondary sealing elements, and a seal support system. Mechanical seals offer several advantages over pump packing, such as improved efficiency, reduced leakage, longer service life, and reduced maintenance requirements.

Selecting the appropriate option between pump packing and mechanical seals requires careful consideration of specific factors related to the pump and its operating conditions. Our sealing specialists have the expertise and experience to guide you through the selection process.

We maintain an extensive inventory of essential sealing components for hydraulic and pneumatic cylinders and systems. Our inventory includes a wide range of standard polypaks, U-cups, O-rings, piston seals, piston cups, wipers, and various other components crucial for effective sealing. We understand the importance of minimizing downtime and keeping operations running smoothly, which is why we prioritize having a comprehensive inventory on hand. We also maintain a selection of common metric components to cater to a wider range of applications and specifications.
