Precision seals for pneumatics

Parker-Prädifa pneumatic seals are the result of decades of experience in materials and profile development. For the pneumatics design engineer, they open up new methods and design techniques, such as properties which give them optimal friction conditions and enable them to retain a lubricating film with the use of lip seal geometry.

Users have an entire range of sealing systems for pneumatic cylinders at their disposal: Rod seals and scrapers, single- and double-acting piston seals, complete pistons with and without mechanical damping buffers, damping rings and combined sealing scraper rings for ISO and short-stroke cylinders.

Parker-Prädifa also offers a wide range of products for custom applications. However, only a portion of them are presented in this catalog: Sealing scraper elements for rotation-proof cylinders, oval double-acting piston seals for flat cylinders, rubberized fiber web seals for cylinders without a piston rod, and special sealing scraper elements for especially high amounts of dirt.
