Series AI 70 & AI 75 is single helical coil spring seals developed for dirty media and clogging type applications. Torque transmission from retainer shell to seal ring is done through drive lugs. All components are held together by a snap ring which helps in easier installation and removal. As all parts are interchangeable, one can covert Series AI 70U to 75U by changing only the seal ring and the secondary seal. This concept is ideal for stock rationalization.
