Our promise to design CRITICAL PARTS that PROTECT.

Critical parts are our PRODUCTS.

Critical parts are our PEOPLE.

Seal designer & MANUFACTUreR | Critical SEALING & POLYMER parts

Our OmniSeal® PTFE spring-energized and rotary lip seals, Rulon® fluoropolymer plastic materials; and Meldin® thermoplastic and thermoset polyimide critical parts are used in core systems with challenging conditions, keeping these systems protected and worry-free. These systems play an important part of our daily lives such as driving a car for work or leisure or flying in an airplane to explore the world; and moving us technologically forward such as processing samples to further medical research, building a better rocket for outer space and going under the sea for energy resources.

With our critical products and people, we PROMISE to deliver the PRECISE FIT and LIFETIME CONFIDENCE to our customers and end users.

Gas Turbine Engines

The most widely used form of propulsion system for modern aircraft and requires high operating temperatures, which our OmniSeal® solution is known for.

Components

The many major and minor pieces on an aircraft must all work together seamlessly. Our products have a critical effect on several of these components, offering reliability, comfort and safety.

Space

A long-time partner in the space industry, we lead with knowledge, invention and vision, starting with Project Mercury, continuing with the Space Shuttle and heading to the future with the Mars and Space Launch System programs.

Automotive

Partnering with L+S, we acquired expertise in injection-molded seal rings and thrust washers for powertrain & transmissions, building on more than 40 years of experience with OEMs, Tier 1 and Tier 2 companies. We strive to reduce friction, leakage, wear, noise, and emission; and contribute to energy-efficient solutions with our OmniSeal® polymer seals and Meldin® thermoplastic products.

Powertrain

We co-develop a wide variety of applications in engine systems, drivetrain and exhaust management which are key in increasing fuel efficiency and reducing CO₂ emissions.

Active Safety

Systems that play an important part to minimize or avoid collisions and crashes. We provide precise components in brake assist and actuation systems that are critical in these systems.

Driving Comfort

A key selling point for Automotive OEMs and an important factor in overall safety by reducing driver fatigue on long journeys. We supply key precise parts for steering, suspension systems and climate control.

Electric Drive

A popular alternative in the present and near future, we offer sealing solutions for the battery cooling system and support other applications in this quieter and cost-saving mode of transportation.

Energy

Our PTFE sealing and polymer solutions were introduced to the Oil and Gas sector in the 1970s. Since then, our OmniSeal® spring-energized and rotary lip seals have addressed critical issues including aggressive media, sour gas environment, resistance to rapid gas decompression and extreme cryogenic operating conditions, leading to the next generation of materials that are NORSOK and API certified.

Onshore Drilling, Production & Transport

Our sealing solutions are compliant with API 6A and fugitive emission standards ISO 15848 and SHELL MESC SPE 77-300 for valves in the upstream and downstream sectors.

Subsea Drilling, Production & Transport

We support customer demand for high-performance, subsea equipment sealing solutions compliant with API 17D, addressing extreme pressure and temperature issues.

Cryogenic Production & Transport

Where harsh chemicals and liquefied gasses (LNG and LPG) are present and need to be handled properly, our customers rely on our sealing systems for protection, reliability and lower costs.

Floating Production

A key technology using large and complex turret swivel stacks. Our OmniSeal® seals with back-up rings handle larger diameter sealing systems with ease.

Renewable Energy

We are committed to working with renewable energy technology that is affordable and sustainable such as our OmniSeal® windmill gearbox seals.

Life Sciences

Nurturing a more than 30 year relationship with medical, dental, analytical equipment and pharmaceutical customers, we have become their trusted design and manufacturing partner due to our high purity OmniSeal® spring-energized and rotary lip seals, Rulon® PTFE bearings and Meldin® thermoset polyimide parts, providing a precise level of sealing and meeting the most stringent cleanroom requirements.

Analytical Instrumentation

Used in a number of fields due to cross-functional capabilities, these systems need a high level of data resolution and precision. Our design, materials and manufacturing methods save customers valuable design and test time.

Surgical Tools

Global increase in surgical procedures push tool designers to find less invasive and cost-effective solutions, which we deliver with many sterilization resistant materials suitable for sealing and friction control and over 22 FDA Compliant or USP Class VI materials options.

Healthcare & Medical Devices

One of the many changes experienced in this industry is the growth of devices in wearable, portable healthcare and home healthcare options. We support OEMs so they provide the lowest friction, most reliable components on the market.

Industrial

Our OmniSeal® polymer spring-energized and rotary lip seals, Rulon® PTFE bearing materials and Meldin® thermoset polyimide products are used in compressors, pumps, valves, commercial machinery and food industry equipment where it is critical to be contaminant free, withstand aggressive media and handle extreme pressures and temperatures. We ensure our customers a lifetime of confidence with equipment being as maintenance free as possible.
