Our diverse range of sealing products includes specialized options for various industrial applications. From pneumatic and hydraulic seals to mechanical face seals.

Pneumatic Seals

In general, pneumatic seals are used to retain liquids, such as air and gas. Advanced Sealing Technology supplies a number of seals that have been specially developed for pneumatic applications: where cylinders and valves are activated by air. Pneumatic seals are used in dynamic applications, often with high speeds and generally with rotary and linear movements. That is why these seals also require advanced properties which are reflected in the optimized materials we use.

In addition to our standard pneumatic seals tailor-made solutions can of course always be developed. Contact us to find out more about our possibilities.

Custom Hydraulic Seals

Hydraulic systems require specialized seals to withstand high pressures, extreme temperatures, and transverse forces while preventing fluid leakage. Key components include rod seals to stop external leaks, piston seals to maintain pressure differential for movement, guide rings to prevent metal-to-metal contact by absorbing transverse loads, and wipers to block contaminants like dirt and moisture.

We offer durable, high-efficiency hydraulic seals engineered for peak performance and minimal maintenance. Contact us today or request a quote to discover how our custom sealing solutions can support your equipment.

O-Rings

With current technology, the O-ring is indispensable as a seal and can therefore be used in almost all industrial branches, such as aerospace, the car industry and general mechanical engineering. O-rings are used not only as a sealing element, but also as an activating element for hydraulic seals and scrapers.

O-rings are so commonly used today because they are cheap to produce and easy to use. This means they are cost-effective and perform at a high level. We offer O-rings in all kinds of sizes and materials, allowing the O-ring to seal virtually all liquid and gaseous media. If you would like to know more about the possibilities of our O-rings, please feel free to contact us or request a no-obligation quote below.

Mechanical Face Seals

Mechanical Face Seals are specially developed for rotating applications in extremely harsh conditions. These Mechanical Face Seals resist wear and prevent the ingress of abrasive and aggressive external media.

With or Without O-Ring

There are two different types of Mechanical Face Seals: A type that uses an O-ring as the second sealing element and a type that does not use an O-ring but an elastomer with a rectangular cross-section as the second sealing element.

Heavy Duty Seals

Heavy Duty

The applications of Mechanical Face Seals Mechanical Face Seals are mainly used for seals in machines that have to produce under extremely harsh conditions and whose seals are therefore heavily subject to wear. Think of bulldozers, black trucks, agricultural machines and transport systems, where the seals are very suitable for use in gearboxes, mixing machines and wind turbines.

In any case, a maintenance-free and life-long seal is required. If you would like to know more about the possibilities of our Mechanical Face Seals, please feel free to contact us.

High-Performance PTFE Seals in Modern Industrial Applications

Engineered Polytetrafluoroethylene (PTFE) seal compounds provide the mechanical durability, low-friction behavior, and extreme thermal stability required when standard elastomeric seals reach their operational limits. Designed to function reliably across temperature ranges from cryogenic conditions up to +260 degrees celcius (+500 degrees fahrenheit) and operating pressures up to 800 bar.

PTFE offers universal chemical compatibility against aggressive hydraulic fluids and solvents. By combining near-zero friction to eliminate stick-slip phenomenon with specialized filler reinforcements like bronze, carbon, or glass fiber, these spring- or elastomer-energized sealing configurations deliver uncompromised extrusion resistance and extended service life in critical fluid power, chemical processing, and dynamic hydraulic equipment.
