What Is a Gasket Sealant and How Does It Work?

Gaskets are designed to be compressed between two surfaces so that a space is optimally filled, they can lose their quality and performance over time as they are faced with heat, pressure, chemicals, and other stressors. As this can eventually lead to a gasket failure or a leak, it is often recommended that one takes advantage of sealants to better ensure reliability. In this blog, we will discuss gasket sealants and their functionality, allowing you to determine whether or not it is something that you could take advantage of for your needs.

While gaskets are specifically engineered to completely fill the space between surfaces, they are by no means perfect. If even one imperfection or tear were to occur for any reason, the integrity of the seal could be jeopardized, leading to a leak. Regardless of whether a gasket is made from carbon fiber or robust steel, all can crack or warp. Imperfections can source from various things, such as an issue during manufacturing, installation, or during typical use. Nevertheless, any form of irregularity on the surface of the gasket will have a detrimental effect on its ability to provide a reliable seal.

Gasket sealants are considered to be a type of adhesive, and their use allows one to strengthen and reinforce an installed gasket. Gaskets are typically shaped to accommodate the surface that they are to be compressed between, and they can be reinforced by having a gasket sealant applied to the front and back side of the component. Then, the gasket can be pressed between the mating components. Once set, there should be a much lower chance of any leak occurring.

Most gasket sealants are able to be set at room temperature, making their use easy as one does not need to utilize ultraviolet (UV) exposure. Instead, all one has to do is apply the sealant as needed across the assembly, and it will begin to set naturally over time. It is important to give the sealant a good amount of time to harden before putting any force on the connection, as it will ensure that all cracks and spaces are filled for the utmost integrity.

With numerous gasket sealants available on the market, it is important that one takes the time to find the best option for their needs. For thin paper or cardboard gaskets, a shellac-type sealant is best. Meanwhile, environments where temperatures may reach upward of 500 degrees Fahrenheit may require a high tack, copper gasket, hylomar, or RTV silicone sealer. To best determine what type is best for your needs, refer to manufacturer specifications or conduct application-specific search.
