Trying to figure out what type of gasket is best for your particular situation can be quite difficult. There are many different types of gaskets. Each has a specific goal and ability. For instance, gaskets in your water lines. You will want to choose a water line that is designed for it. Therefore, you need to gain an understanding of the PUB approved gaskets for potable water.
You may not think of it at first, but temperature is a key factor in choosing the right gasket for your water lines. EPDM is the best rubber gasket material. It is safe for water lines that reach a maximum temperature of 350-400-degrees. If you like the hot water in your kitchen to exceed this temperature, you will want higher heat gaskets. Most of the time, this is not an issue for homeowners, but it is worth considering.
Cold water gaskets are a lot more forgiving. You can choose any that have been approved of for use on potable water lines. However, you need to make sure that the water line will push out no more than 90-PSI if the valves are closed. Otherwise, you could end up damaging the gasket material.
A final consideration is whether there will be a lot or a little chemicals in the water. This is typically for drains, but may still be worth considering. There are certain chemicals that can cause a rubber gasket to become weakened. As this happens, there is an increased risk for leaks to appear. These leaks can damage the foundation of your home or office.
If you are still uncertain, you may choose to base it on size. Most gaskets are not one size fits all. Some have bolt holes for added security. They may be very small in diameter or quite large, depending on where they are needed in your home or office space.
In all cases, if there is any chance that you will one day use the water to cook with or drink, you need to make sure that it is PUB approved. This will mean that it is made with non-toxic materials so that even years of use will not cause damage to your overall health. After all, who wants to drink healthy water only to discover that it is what caused them to be sick?
