Materials and Properties
Omniseal Solutions offers various high-performance polymer compounds for seal jackets, including virgin PTFE, polymer-filled PTFE, and UHMW-PE, each with specific properties for different applications.

Material Codes and Properties
PTFE-based materials for seal jackets are characterized by temperature range, coefficient of friction, wear factor, tensile strength, elongation, and hardness. For example, A40 is FDA compliant, while A56 offers outstanding heat and chemical resistance.

Industry Standards and Qualifications
Materials meet standards like NORSOK M-710 and API 6A for oil and gas, and FDA, EU regulations, and USP Class VI for life sciences, ensuring safety and resistance to extreme conditions.

Seal and Energizer Options
Various seal options include elastomeric O-ring and metallic spring energizers, designed for static and dynamic applications with specific recommendations for radial and face sealing.

Back-up Rings
Back-up rings prevent seal extrusion at high temperatures and pressures, with designs like rectangular, triangular, and L-shaped, recommended based on application conditions.

Friction and Load Calculations
Friction is influenced by the seal material's coefficient of friction and lubrication. Omniseal provides charts and formulas for calculating friction values in non-lubricated conditions.

Specifications and Procedures
Minimizing extrusion gaps is crucial to prevent seal failure under high pressure and temperature. Guidelines for gland width and extrusion gap dimensions are provided, recommending back-up rings for enhanced performance.

Surface Finish and Hardness
Smoother surface finishes reduce wear and extend seal life. Recommended Ra values are provided for various media and applications, emphasizing surface hardness for different motion speeds.

Seal Design Variations
Various seal designs, such as skived lip and extended heel, are suited for specific applications, offering improved resistance to extrusion and environmental exclusion.

Market Applications
Omniseal products are used in oil and gas, aviation, and life sciences, capable of handling extreme conditions like high pressure, high temperature, and cryogenic environments.

Key Recommendations
Consult Omniseal's technical support for specific applications, especially under extreme conditions. Proper gland design and surface finish are critical for preventing seal failure.

Compliance and Manufacturing Standards
Omniseal® products comply with FDA and USP Class VI standards, manufactured in clean rooms to ensure high purity and chemical compatibility.

Life Science Applications
Used in HPLC/UHPLC, surgical tools, and pharmaceutical equipment, Omniseal® seals perform well in dry and poorly lubricated environments.

Product Specifications
For saturated steam applications, seals operate between 21°C to 137°C, at pressures up to 3.5 BAR. For high-pressure applications, custom seals function at temperatures from 20°C to 40°C, pressures up to 1,034 BAR.

Electronics Market Applications
Omniseal® products are used in semiconductor processing equipment, offering high purity and chemical resistance under high pressure and temperature.

Case Studies and Product Features
Omniseal® 103A and 400A radial seals are suitable for high temperatures and pressures, while APS and RP II series offer low friction and high spring loading.

Installation and Handling
Careful installation is required to prevent damage. Special tools are recommended for closed groove installations, and hardware surfaces must be free of scratches.

Installation Procedures
Mechanical compression tools ensure seals return to original diameter after expansion. Special considerations are noted for installing multiple seals on a common shaft.

Special Seal Designs
Specialized designs include Anti-Blowout Rod Seals, Integral Piston Seals, and Bidirectional Seals, each for specific applications.

Chemical Compatibility Guide
A guide rates the chemical compatibility of materials like PTFE and UHMWPE with various chemicals, considering temperature effects.

Warnings and Recommendations
Avoid using hand tools for seal installation to prevent damage. Consult technical support for closed gland designs.

When Our Spring-Energized Seals (SES) Journey Began What Is the Omniseal® Solution? Omniseal® seals are the Omniseal Solutions' product family of spring-energized PTFE seals made from high-performance polymer materials. In the early 1950s, Omniseal® seals were ﬁrst developed by three separate entrepreneurs in Southern California, each introducing a unique design: Omniseal®, TEC Ring and RACO® seals. These seals were developed to provide improved performance over soft elastomeric seals and hard metal gaskets in applications involving cryogenic liquid propellants in various rocket engine programs....

Our Spring-Energized Seals and Their Part in History Hardware that was built for space vehicles in the Apollo moon exploration program contained a variety of Omniseal® products. The Lunar Lander at the Smithsonian National Air and Space Museum in Washington, D.C., displays our RACO® seal (a design within the Omniseal® product family), which was used to seal the triangular shaped window on the space vehicle. Omniseal® seals were designed and used in the first space shuttle launched in 1981 by NASA as part of their STS (Space Transportation System) program. Since that time, our seals have been...

How Our Omniseal® Spring-Energized Seals Work The Omniseal® spring-energized seal is a spring-actuated, pressure-assisted sealing device consisting of a PTFE (or other polymer) jacket partially encapsulating a corrosion-resistant metal spring energizer. When the Omniseal® seal is seated in the gland, the spring is under compression, forcing the jacket lips against the gland walls and thereby creating a leak-tight seal. The spring provides permanent resilience to the seal jacket and compensates for material wear and hardware misalignment or eccentricity. System pressure also assists in energizing...
