The test results indicate that blistering in rotary lip sealing is not only a problem of fluid compatibility but strongly refers to the thermal and mechanical load of the seal in contact with the rotating shaft. Blister-filling may be achieved in a macroscopic way without adsorption and diffusion of the sealed fluid. This work examines the role of important factors of a blister formation in rotary lip sealing and therefore helps to analyze and prevent blistering in practical applications.
