A sealant is a material that closes small openings between objects to prevent air or liquid from passing through. With a lot of parts joined together inside your vehicle, a sealant is a helpful tool that could prevent these parts from leaking. Read on to know the different types of automotive sealants that you could apply on various car parts.
Choose a sealant for the right car part
Among the different types of sealants for various applications, there are three common types that can be used for your vehicle. These are the room temperature vulcanizing (RTV), anaerobic, and pipe joint compound sealants. You can find a short description for each and their uses below:
- Room temperature vulcanizing sealant
- Anaerobic sealant
- Pipe joint compound
A RTV sealant is used mostly for engine rebuild or repair. It's also the best choice for sealing leaks around the engine. It can even replace a conventional gasket in some applications. However, this type of sealant is not applicable in very high temperature, so be careful when using this type of sealant.
Used mostly on machined surfaces, an anaerobic sealant hardens when there's no air that surrounds it. This sealant is best applied inside your car engine because it can withstand temperature beyond 300 degrees Fahrenheit. Remember not to let an anaerobic sealant fill any threaded hole because it will have an effect on the torque readings.
This is a type of universal sealant that lubricates joints of fuel lines and pipes in your vehicle. The temperature range for a pipe joint compound can go as low as -65 degrees Fahrenheit and go as high as 400 degrees Fahrenheit. Choose a type of pipe joint compound sealant that doesn't contain lead or asbestos because these chemical are dangerous to your health.
Some tips to remember about sealants
- Choose the appropriate amount of sealant that you need. You can check the different amounts which range from three to sixteen ounces. If you want to stock a sealant for your garage, then go for the 16 ounce size.
- The type of sealant you choose for a specific car part is critical. You should read if a sealant is applicable or not on a specific part because it can result to a big problem.
- Always cover the sealant when not in use. Although sealants have different drying rates, most types will dry up quickly, and you won't be able to use them again when they harden.
