Each material offers unique properties such as、、，。The seal shown in Fig. 14.2 is a relatively simple design; most automotive seals are more complex. Dust lips are often used to keep outside contaminants away from the oil lip seals; such seals thus have undercuts that make demolding more difficult. Fluoroelastomer compounds used for such undercut shapes must have reasonably high elongation at break at molding temperatures to avoid tearing the part during demolding. The metal insert is often U-shaped, and stock may be molded to form a thin layer over the outside of the insert. Since both compression and injection molding methods are used, suppliers of fluoroelastomers for shaft-seal applications often must provide different versions of the same polymer composition-medium to high viscosity for compression molding, and low to medium viscosity for injection molding. Different precompounds may be necessary to accommodate relatively long compression-molding times at low temperature and very short injection-molding times at high temperature.
small rubber gasket. When a gasket fails to perform its duty, the repercussions can be both costly and time-consuming to rectify. Leaks lead to resource waste, downtime, and potentially hazardous situations. It is in these moments that the value of the small rubber gasket becomes strikingly apparent.Oil seals require sufficient time to solidify and cure. Premature use of equipment with newly installed oil seals can compromise the integrity of the oil seal and may damage your machine. Refer to the supplied instructions for the time frame allocated for the seal to cure.
Early engines used O-rings (also called packing rings or toric joints) as seals (first patented in 1896). These are just mechanical gaskets in the shape of a torus (a circular ring--like a lifesaver), seated in a groove and compressed during assembly between two or more parts. It creates a seal at the interface. However, O-rings require a fluid film to lubricate them. They have limited usefulness in vacuum application and at extremes of temperature. The modern oil seal represents a significant improvement over the simple O-ring because it effectively seals in lubrication and prevents contamination from outside under a wide range of pressures and temperatures.

Our suppliers try to provide the best quality oil seals and products are in some cases optimised to improve performance and fitment. Corteco is one of these brands, whose case studies we have listed for you.
