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.

Assembling the oil seals is only possible with the right assembly tools. Due to the high risk of damage during assembly, it is important that you have tools with which you can work carefully. A bearing fitting tool set is ideal.

Spring seals are the perfect solution when regular seals are unable to produce a leak-proof mating surface. They are the best substitute for sealing applications involving machinery as they are capable of resisting more heat and pressure than other types of seals.

When selecting the 75x100x10 oil seal for a specific application, it's essential to consider factors such as the operating temperature, speed, and pressure of the equipment. Different materials and designs are available for oil seals, each with its own set of characteristics and advantages. Consulting with a knowledgeable supplier or manufacturer can help you choose the right oil seal for your needs.
