- Rod Seals These ensure that no hydraulic fluid escapes through the rod exit. Properly functioning rod seals are vital for the cylinder's efficiency.

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.

A hydraulic cylinder packing kit consists of various seals and gaskets designed to prevent fluid leakage and ensure optimal performance of hydraulic cylinders. These kits serve as barriers between the high-pressure hydraulic fluid and the external environment, thus protecting the system from contaminants and maintaining operational efficiency. Packing kits come in various designs and materials, depending on the specific application and operating conditions.

The design of high pressure rotary seals considers several key factors, including the type of fluid being sealed, operating temperature, pressure, and the speed of rotation. Typically, they are made from advanced materials like elastomers, PTFE (polytetrafluoroethylene), and specialty composites that can endure extreme conditions. The seal's design often incorporates a lip that makes contact with the rotating shaft, creating a barrier against the pressure.
