Why Choose OmniSeal® Critical Parts for Your Application?

Oct 13, 2017 / by Geert Vanthienen

Are you familiar with OmniSeal® polymer spring-energized seals and rotary lip seals? Ever wonder why spring-energized seals have a jacket and spring while lip seals have a metal casing? How do these two unique designs benefit your application? Lifetime confidence is just one of the key benefits; here are several more reasons OmniSeal® parts should be your seal of choice.

Function or failure? Confidence or compromise? Which of these traits best describe your sealing solutions? At Saint-Gobain Seals, we believe critical parts demand critical precision that can only be achieved via expert material formulation, engineering, manufacturing and testing with the end result instilling lifetime confidence. Here’s how:

Formulated to solve problems

OmniSeal® PTFE rotary lip seals are driven to solve your toughest sealing challenges; they are always co-designed with customer input to meet your unique specifications. The metal casing design is a distinctive sealing solution that bridges the gap between traditional elastomer lip seals and expensive mechanical face seals. Unlike traditional designs, the rotary lip seal overcomes challenges such as temperatures, speeds and pressures to provide your engineers with a cost-effective sealing solution that does not compromise on performance for dynamic applications.

Engineered for cost savings

OmniSeal® spring-energized seals broke the manufacturing mold (so to speak) by being among the first seals where the fluoropolymer-based jacket of the seal was injection molded, unlike traditional materials which were fully machined. With a molded solution, there’s the potential to save significantly over machining, which can be a significant advantage in the total cost value of building assemblies.

Manufactured and tested for precision

Our OmniSeal® spring-energized seals incorporate a spring-actuated, pressure-assisted sealing device constructed of a PTFE (or other polymer) jacket that is partially encapsulated by a corrosion-resistant metal spring energizer.  

To manufacture these unique devices, we built a special assembly line fitted with unique cutting tools. These manufacturing tools allow us to offer a wide variety of part geometries. All manufacturing is done in-house within our global manufacturing facilities and parts are tested for critical performance and lifetime confidence. We also invest heavily in our R&D for advanced simulation tools such as FEA (finite element analysis) to model, design and validate complex designs to ensure they meet your specifications.

Application versatility for best results

Our OmniSeal® products are an ideal solution for extreme applications where low friction, high load and extreme temperatures are a concern. Design versatility including sealing jacket with several spring types to 2- or 3-lip designs that meet the challenging application requirements offer customized solution for your needs. Given that sealing solutions often control the fundamental functioning of a system, longer life means that failure is not an option.

Where will you find OmniSeal® spring-energized seals and rotary lip seals?  
In Aerospace:

First designed in the 1950s and used for several space programs, our OmniSeal® spring-energized seals really made a difference with NASA’s Space Transportation System when the first space shuttle was launched in 1981. Since then, we’ve worked with hundreds of engineers from NASA and other key space visionary companies to design and manufacture thousands of seals in the main engine, life support systems, external tanks and launch vehicles. The seals are now used to solve temperature, pressure and weight requirements of jet and helicopter engine seals, gearboxes, rotors, and hydraulic/pneumatic controls.

Once established in aerospace, OmniSeal® products have since excelled in other industries:

In Automotive:

In automotive powertrain and transmission, OmniSeal® seals help to reduce friction and CO2 emissions to deliver a more energy-efficient solution. And just as in the aerospace market, they deliver a better weight-to performance ratio for greater fuel savings using our precision control capability. Look for them in engine shaft seals and fuel injection pumps.

In Energy/Oil & Gas:

In this extreme and hazardous field, OmniSeal® sealing parts are very valuable. The material helps to solve the reliability problems that can occur when elastomer seals come in contact with corrosive oil and gas (or sour gas), plus varying temperature and pressure requirements and sudden high-pressure changes. Look for them in pressure conditions up to 20,000 psi and temperature ranges from cryogenic to 300°F and above.
