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.

Brake drums are crucial components in certain vehicle braking systems, particularly in older vehicles, heavy-duty trucks, and some industrial machinery. The brake drum works together with brake shoes to create the friction necessary to slow down or stop the vehicle. Over time, due to wear and tear, the thickness of the brake drum can decrease, which raises serious concerns about safety and performance. Therefore, understanding the minimum brake drum thickness is essential for all vehicle owners and operators.
