The production of large seals for challenging applications is not simply a matter of scaling up know-how of traditional seal design. The reason is that XXL sizes not only pose particular handling challenges in the manufacturing process, but do so even earlier, in the design and testing stages. As a specialist in engineered materials, engineering design and process technology Parker Prädifa offers an extensive portfolio of large-size seals and moldings made of polymers such as NBR, EPDM, FKM, PTFE and PEEK, as well as metal.

Polymer seals made from machinable materials:

Using a new type of manufacturing technology, Parker Prädifa is able to produce polymer seals from machinable materials like PTFE, PEEK or TPU up to a diameter of 4.5 meters.

Elastomer seals:

Thanks to innovative continuous vulcanization manufacturing technology there are practically no size limitations for elastomer seals.

Metal seals:

Spring-energized metal C-rings can be produced in diameters of up to 7.6 m. Non-rotationally symmetric E-, O- and C-seals can be produced in lengths of up to 2.3m.

Range of application:

In a wide range of industries, in addition to average-size and miniaturized equipment, large-scale systems are used that require components and sealing systems matching the size of the equipment. Examples include manufacturing plants and equipment, buildings and pipelines, tunnel construction and mining, energy, high-tech medicine, aerospace and many others.
