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.

One of the primary advantages of asphalt roofs with cooling granules is their contribution to energy efficiency. Traditional black asphalt roofs can reach temperatures up to 150 degrees Fahrenheit or more under direct sunlight. In contrast, roofs equipped with cooling granules can maintain much lower surface temperatures, often around 10-30 degrees cooler. This temperature difference translates directly into energy savings; studies have shown that homes with reflective roofing materials can reduce energy costs by as much as 20%. As energy prices continue to rise, these savings can have a significant impact on household budgets.
