Common Applications for Silicone Rubber Gaskets

While a gasket may be inexpensive, its failure can result in substantial damage. That's why PGC encourages customers to consider the entire assembly to ensure that the gasket functions effectively with all other parts. Silicone rubber is typically the best choice for custom gaskets because of its excellent dimensional stability, ability to protect sensitive components, and effectiveness in keeping out contaminants and moisture.

Properties of Silicone Rubber Gaskets

Silicone rubber is a versatile and reliable material that offers various solutions for various applications and budgets. It is known for its exceptional temperature resistance, remaining functional in extreme conditions from -67 to 572 degrees Fahrenheit. Additionally, silicone rubber is highly resistant to UV rays and ozone, which can degrade weaker materials over time. Its broad chemical resistance protects it from many different substances in diverse environments.

When used for gaskets, silicone rubber delivers a high-performance seal, effectively preventing leaks between parts in an assembly. Given these advantages, it's unsurprising that silicone rubber gaskets are widely utilized across industries, including aerospace, transportation, food service, and construction. Silicon is available in cellular, solid, and reinforced configurations that cater to soft, medium, or firm applications, ensuring customers find the right fit for their needs.

Silicone Rubber Gaskets for Aerospace

Silicone rubber is an ideal material for airplane gaskets, space shuttles, and other aerospace equipment due to its resistance to extreme temperatures, UV rays, and ozone. In such demanding environments, components must reliably perform under stress from external conditions, especially when human safety is at stake.

Silicone rubber gaskets are used in various aerospace applications, including engine and vent ducts. Testing has shown effectiveness in sealing doors, windows, HVAC systems, and instrumental panels. Additionally, silicone rubber gaskets excel at vibration dampening and thermal insulation, making them well-suited for critical aerospace components.

Transportation Uses for Silicone Rubber Gaskets

Silicone rubber is well-known for its strength, durability, and stability in extreme environments, making it resistant to various environmental stresses. These characteristics make it suitable for multiple transportation applications, including personal, commercial, and industrial vehicles such as heavy machinery, buses, and trains.

In cars, silicone rubber gaskets reduce vibrations and create high-performance radiator seals that ensure the vehicle runs efficiently. In mass transit applications, silicone rubber serves multiple purposes. These include vibration dampening, HVAC seals, interior door seals, and seals around electrical enclosures, which ensure the vehicle and its occupants are well-protected.

Commercial Applications for Silicone Rubber Gaskets

Silicone rubber gaskets are used in various commercial applications. They serve as effective seals for HVAC systems and doors in the construction industry. Certain types of silicone rubber and anti-vibration pads also work very well. These gaskets are often used in food processing machinery and industrial oven seals in the food industry.

At PGC, we offer a wide range of custom gasket and sealing technologies designed to maintain precise tolerances, protect sensitive components, and prevent the entrance of dirt and moisture. Our engineers leverage their knowledge to help customers choose the right gasket for their application so they can reduce costs and improve performance.
