The materials used in manufacturing hydraulic seals are also vital to their performance. Common materials include rubber compounds, polyurethane, and PTFE (Polytetrafluoroethylene). Each material offers different advantages and is selected based on the operating environment. For example, PTFE seals are highly resistant to chemicals and extreme temperatures, making them ideal for demanding applications.

The concept of a swing extension spring draws parallels to the physics of springs in engineering. In a mechanical context, springs are designed to store potential energy, which is then converted into kinetic energy when released. This principle can be applied to athletic movements, where the body acts like a spring. By effectively utilizing the body's natural biomechanics, athletes can maximize their performance.
