A rotary shaft seal, also known as a lip seal or radial seal, is a device that creates a barrier between two environments the area where the rotating shaft operates and the external atmosphere. In high-pressure applications, these seals are engineered to withstand significant operational pressures, often exceeding several thousand psi. They are utilized in applications such as hydraulic pumps, turbines, and engines, where preventing fluid loss is critical.

The complexity of the manufacturing process also plays a significant role in determining the price of oil seals. Production involves several steps, including material preparation, molding, and quality control. High-precision seals that are engineered for specific applications typically come at a higher price point due to the advanced technology and expertise required in their production. Manufacturers with stringent quality control measures may also incur higher operational costs, which can be passed on to consumers through increased prices.

A dust lip seal, often made of elastomers or polymers, is designed to fit closely around rotating shafts or in applications where parts move relative to one another. The primary function of this component is to create a barrier against external contaminants while allowing internal lubrication to remain intact. Typically, dust lip seals feature an outer lip that provides the necessary seal against particles and a secondary inner lip that retains lubricants within the assembly.
