Using our expertise in high-performance polymer compounds, we have developed over 500 proprietary formulations in house that are used to meet the demands in a number of critical applications. These materials are compounded and processed to be optimized for tribological (friction and wear), mechanical and thermal properties.
Rotary lip seals may have garter springs to help assist with the higher than acceptable runout/misalignment of the shaft and improve sealing under high speed. The springs may also add a consistent load combined with polymer compounds.
Design expertise allows for collaborative customer designs that are engineered to meet even the most challenging applications. In addition to series 10 to 90 that are shown as catalogue designs, we have the ability to go far beyond and address your custom sealing needs. Knowledgeable and experienced engineers are ready to co-develop solutions with your technical team.

Consisting of a family of proprietary materials that are composed primarily of polytetrafluoroethylene (PTFE) based resins, the different grades of this high-performance polymer material have been specifically formulated to meet the needs of challenging applications and the different applicable certifications. For example, some grades were designed to be USDA, USP, and/or FDA compliant and therefore well suited for life science equipment such as harmonic scalpels or chemical analyzers.
Omniseal Solutions has diversified its expertise in processing polymer materials to allow for any problem to be solved. Whether the application requires the design to solve corrosion issues, chemical compatibility, lubrication-free, electrical insulation improvement, or any other issue, the design starts with choosing the right material.
Omniseal® Rotary Lip Seals are metal-cased PTFE-based shaft seals using a flexible lip design to maintain radial sealing contact. They combine the low friction and chemical resistance of PTFE with the robustness of metal cases, enabling effective sealing in dynamic rotary applications.
Omniseal® Rotary Lip Seals offer outstanding chemical resistance, low friction, wide temperature tolerance (–60 °C to +230 °C; –75 °F to +450 °F), shaft speeds up to 35 m/s (up to 100 m/s in special designs), and pressure handling up to 34 bar (500 psi).
Omniseal® Rotary Lip Seals are used across aviation (jet engines, rotorheads), industrial equipment, and life science applications like pharmaceutical mixers—industries that demand robust, dynamic rotary sealing solutions.
Yes. Omniseal® Rotary Lip Seals are available in multiple series, ranging from the economical 10 Series for general-purpose sealing, to the 20 Series with higher lip loads for gases and abrasive media, the 30 and 40 Series with threaded lips to pump media away, the 50 Series for low torque and long environmental life, the 60 Series with spring-loading for misalignment or runout, and the 70, 80, and 90 Series with double-lip designs for high-pressure, high-speed applications.
Omniseal® Rotary Lip Seals are made from proprietary high-performance PTFE-based polymer compounds (over 500 material blends) optimized for tribological, chemical, and thermal performance. Some designs also include garter springs to maintain consistent lip loading in misaligned or high-speed rotary scenarios.
