When you need to work in extreme conditions

Freudenberg Sealing Technologies delivers the performance you need

Our customers already know they can depend on the quality and performance they get from Freudenberg Sealing Technologies. Whether it's in their hydraulic cylinders, pumps, motors or valves, performance is key. And we deliver the kind of performance to the table that will stand up to extremes of high and low temperature and pressure without missing a beat.

When you have a serious sealing problem, that's where Freudenberg stands out from the competition. We understand the often harsh and extreme environments your hydraulic equipment needs to withstand, which is why we've developed materials that are engineered to perform longer and under the demanding environments you consider to be "just another day."

Simply put, we design seals that last longer and operate in environments that are among the most demanding anywhere on the planet.

How is this possible? One key element in our ability to outperform is our keen understanding and proprietary knowledge of the next-generation polyurethanes, materials that are proven to perform at levels our competition can only hope to achieve. At Freudenberg Sealing Technologies, we design performance into every product we deliver.

Rotary and Swivel Seals

It is the combination of operating conditions that put Rotary and Swivel Seals to the test. They must withstand pressure loads similar to those in hydraulic cylinders.

Wipers

Wipers in pneumatic and hydraulic cylinders protect the interior of the cylinder from the penetration of external contaminants when the rod is retracted.

Rod Seals

Rod Seals are primarily used in pneumatic and hydraulic cylinders and have the task of sealing the incoming and outgoing cylinder rod.

Guide Rings

Guide Rings have the task of guiding the rods and pistons of pneumatic and hydraulic cylinders and preventing direct metallic contact with the cylinder housing.

O-Rings

Endless O-Rings with a circular cross-section: O-Rings are among the sealing classics par excellence.

Cover Seals

Even if machine elements under pressure are firmly bolted to one another, there is still a so-called static seal gap that must be sealed.

Usit Rings

Designed in compliance with hygienic standards, the Freudenberg Sealing Technologies Hygienic Usit Ring with an elastomer bead is setting new purity benchmarks in the processing industry.
