1. Installation Recommendation
2. Application and properties
Double acting seals, the sealing effect is achieved by the deformation of the section of the O-Rings, and the deformation is determined by the depth of the installation groove. Under pressure, the O-ring has a large surface tension like liquid, used for static sealing more. It is only recommended for better conditions in dynamic applications. System lubrication, pressure, temperature, sealing clearance, speed, medium and surface quality of metal parts determine the service life of O-Rings. It is not recommended if the lubrication is not sufficient during rotary motion.
