Gaskets

Gasket Types, Materials & Applications

What is a Gasket?

Gaskets are thin components that form a pressure-tight seal between two surfaces. They take the form of rings or sheets that fit between a variety of joints and mating surfaces. Gaskets are available in a wide range of materials to suit varied industrial needs, with common options including rubber, cork, metal, foam, paper, and more.

Gaskets are typically used to prevent liquids or gases from leaking out of a system. They are designed to resist fluctuations in pressure and temperature as well as electrical or electromagnetic forces, ensuring a durable seal across environments. In addition to preventing leaks, gaskets are also useful for dampening vibration, reducing sound, and sealing against contaminants. 

Despite their simple construction and installation, gaskets are critical components for protecting mechanical systems. Not only do gaskets prevent leaks into or out of systems, but they also minimize wear, dampen noise, and maintain a more hygienic environment.

Although gaskets form tight seals, they are not appropriate for all sealing applications, and they should not be confused with O-rings or other general-purpose seals. Gaskets are meant to be used in static settings and provide the best seal under compression. Applications with moving parts such as motors, engines, and rotary shafts require more versatile sealing components.

At UIP, we manufacture a wide range of stocked and custom cut gaskets designed to meet a variety of industrial requirements. Whether your application involves high temperatures, strong vibrations, or strict sanitation standards, UIP can deliver precision-cut gaskets for your needs.

How Do Gaskets Work?

Gaskets are designed to fill deformities and connect two specific mating surfaces. These surfaces create a compressive force that seals the gasket into place. Once fitted, this compression allows the gasket to maintain its seal despite changing conditions.

GASKET MATERIALS

Gaskets must be able to maintain a static seal under diverse operating conditions, including at temperature and pressure extremes. Choosing the right gasket composition helps ensure that seals perform well in all required environments.

The most common gaskets in standard applications, non-metallic gaskets are made from materials such as rubber, Teflon, graphite, or compressed non-asbestos fiber (CNAF). They compress easily and are flexible enough to fill deformities, so they are ideal for sealing uneven surfaces. Although most non-metallic materials are not suitable for use in high-pressure or high-temperature settings, a few non-metals can withstand more extreme operating conditions. Graphite gaskets, for instance, can withstand temperatures as high as 460° C.

Industries & Applications

Aerospace

Aerospace

Many materials are used and specific material call-outs are crucial for this industry. Gaskets require certificates of conformance, including batch numbers and cure dates with full traceability.
Automotive

Automotive

Nitrile and Viton” (FKM) are commonly used materials because of their oil and fuel resistance. EPDM is commonly used for door seals, and graphite/non-asbestos materials can be used in the combustion areas of an engine. Silicone is also used for high-temperature applications.
Chemical/Petrochemical

Chemical/Petrochemical

Spiral-wound, metal graphite, and PTFE gaskets provide superior performance for highly corrosive and high-temperature applications.

Electrical

Electrical

Cork, Neoprene, EPDM, and Nitrile materials can be used for sealing and ventilating electrical enclosures, mounts, circuit board support pads, switchgears, and transformer components.
Food Processing

Food Processing

Silicone is used frequently as it is stable at high temperatures and also inhibits bacterial growth. For steam or other high-pressure applications, non-asbestos and/or graphite material may also be used. Other materials include FDA-approved elastomers such as EPDM, which offer chemical and UV-resistance, and other white food-grade rubbers.
Oil & Gas

Oil & Gas

High-temperature and high-pressure environments require special materials, including spiral-wound and ring-type designs made from non-asbestos materials.

Pharmaceutical

Pharmaceutical

Silicone and PTFE are the most commonly used materials for drug processing and conveyor belting. These materials provide a clean environment and low bacterial growth.
Pumping

Pumping

Shaft seals, valve seals, and packings are made from Neoprene and EPDM. Nitrile, Viton” (FKM), PTFE, and non-asbestos materials can also be used for more corrosive applications.
Rail

Rail

EPDM, Nitrile, non-asbestos, and Viton” (FKM) are commonly used for manway gaskets to seal against fuel, oil, and water.
Water/Drinking Water

Water/Drinking Water

NSF/ANSI 61-certified gasket material is the preferred choice in the potable water industry. Other materials used include Red Rubber (SBR) and compressed non-asbestos for wastewater services.
