Disinfectants are another critical component of water purification. Their primary role is to eliminate pathogens, including bacteria, viruses, and protozoa, ensuring that the water is safe for human consumption. Chlorine is one of the most widely used disinfectants due to its effectiveness and cost-efficiency. However, alternative disinfectants such as ozone and ultraviolet (UV) light are gaining popularity, especially in applications where chlorine's byproducts may pose health risks.

Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
- One common issue associated with a faulty valve cover gasket is oil leakage. As the gasket ages or becomes damaged, it can crack or shrink, allowing oil to escape. This not only results in a messy engine compartment but also leads to a loss of lubricant, which can cause increased wear on engine parts and potentially lead to more severe damage.

- NBR. NBR has high wear resistance and good oil resistance. It is an ideal choice in moderate-high temperatures and cold temperatures from -40°C to 100 °C.
- Labyrinth seals are another type of mechanical oil seal that uses a series of grooves and barriers to create a labyrinthine path for oil to travel through
mechanical oil seal. This design helps to prevent oil leakage by trapping oil within the seal and redirecting it back into the system. Labyrinth seals are commonly used in high-speed applications where traditional lip seals may fail.- Oil seals are commonly made from materials like nitrile rubber (NBR), which offers excellent resistance to oils, greases, and a wide range of temperatures.
