The electronics, aerospace, military, and appliance industries use gaskets in the production process. Gaskets are sealing devices, often designed in the shape of rings and sheets, and are made of deformable materials. A gasket creates pressure-tight seams between stationary components. These seals are typically resistant to fluctuations, temperature, pressure, and sometimes even electromagnetic or electrical forces. Gaskets are usually more malleable than the multiple stationary components, as it uses compression. When you place a gasket between harder surfaces, it conforms to the surface’s shape.
For many manufacturing processes, choosing the proper type of gasket is vital as they come in numerous specifications. Gaskets are made from various materials, including composite substances, foams, corks, plastics, rubbers, and metals. They are also available in multiple designs, such as Kammprofile, spiral wound, double-jacketed, and jacketed varieties. Based on your project’s cost and the gasket’s specific utility, you should look for a gasket with the right combination of design and material. Gorilla Gasket is a custom gasket manufacturer that can provide you with the gasket you need.

Are Gaskets Necessary?
Even though gaskets serve the critical function of sealing joints, you can use similar devices in their place for specific tasks. You will need gaskets to prevent water leakages in units as they help in forming a barrier between the internal and external elements. However, o-rings are used instead of gaskets in certain tasks where the resistance offered by standard gaskets is insufficient.
Depending on your needs, gaskets could be more beneficial to you than an o-ring or a shim. However, you should only choose a gasket whose design suits your purpose. Even though there are numerous kinds of gaskets, you need to select the best one as per your specific need.
Gasket Types
Jacketed Gaskets: These gaskets offer the same durability and resistance as an external metal coating and the flexibility and efficiency of plastic or rubber gaskets. Single-jacket gaskets have metal coverage and soft filler along one face of the gasket. On the other hand, double-jacketed gaskets have fully-coated metal facing, and they provide improved corrosion, pressure, and temperature resistance. Different variations such as French Style jackets and corrugated jacketed gaskets are coated on either the gasket’s outside or inside.
Solid Gaskets: These gaskets are usually made of metal and are cheaper than jacketed gaskets. Solid gaskets have high pressure and thermal resistance. However, they form a seal only after receiving a higher compression force. They are also usually effective against a surface that is harder than the metal.
Spiral Wound Gaskets: These gaskets are made by combining synthetic rubber or softer plastics with metal in a spiral shape. Spiral wound gaskets could be reinforced with additional metal layers without filler. The gasket’s unique design offers high physical stress and thermal resistance, along with resilient sealing and flexibility. These gaskets are typically used in heat exchange systems, pumping, and piping.
Kammprofile Gaskets: These gaskets have a malleable sealing material covering their corrugated metalcore. Along with having a solid tensile core, these devices are also quite flexible. They are used in heat exchange systems because of the reliable support they offer. These gaskets can also be repaired, which makes them relatively cost-effective.
Gasket Materials
Metal: Several kinds of gaskets are made of metal or non-metal and metal mixtures. Typically, these gaskets are formed with brass, stainless steel, steel, nickel, copper, and aluminum. These materials offer high pressure, corrosive, and thermal resistance, along with tensile strength and excellent durability. However, metal gaskets have limited flexibility. This is why a combination of metal and ‘soft filler’ like plastic and rubber compounds are often used to make gaskets.
Plastic And Rubber: As rubber has elastomeric properties, it is often utilized in gasket production. These gaskets do not lose their attributes or suffer from permanent damage even after undergoing high degrees of deformation. Neoprene, Viton, and nitrile are the rubber types frequently used to make gaskets. Specific polymers like polyvinyl chloride, thermoplastic rubber, and thermoplastic elastomer are also utilized in gasket production as they have similar qualities to rubber.
Silicone: As silicone is highly resistant to extreme temperatures, it is often used to make gaskets. Silicone gaskets are especially useful in an outdoor setting as silicone is also resistant to ultraviolet light. They also have wide usage in the transit and electronics industries. Even though silicone gaskets are available in sponge or foam varieties, their tensile strength can be improved, and electrical and thermal conductivity can be adjusted once reinforced with other materials.
