Yes, there are. Always wear safety gloves when handling gaskets, as some of the materials used can be very harmful. This is even caution if there are metal gaskets, as they tend to be very sharp. Always store gaskets in a safe and secure location where dangerous items are, like chemicals or sharp objects. Avoid exposure to extreme temperatures, as they may reduce the toughness of the gasket material. Keep them away from moisture and any electrical sources.
Yes, they do. Most gasket sets are designed from premium-quality material with enhanced heat resistance. Some metals used are even exposed to more than 600 degrees Celsius. There are also composite and ceramic fiber gaskets that can withstand even more. Consider gaskets that can bear the typical temperature ranges of the user's equipment.
Yes, it can. Once the gaskets start wearing out and creating openings, they will allow the fluids to mix. This will lead to one of the most dangerous consequences – overheating. Once the coolant and oil start mixing, there will be no cooling for the engine, which will lead to an increase in temperature. By this time, the damage will already be extensive. Regular maintenance and inspection of the gaskets will help identify signs of wear early enough.
