Gaskets and seals are used in a wide range of equipment across various industries. The purpose of these components is to function as a seal between two mating surfaces and fill any gaps or imperfections between them. If you require custom gaskets or seals for your application, Elastomer Technologies, Inc. (ETI) has the equipment and expertise to produce top-quality components based on your specifications.

Our services and capabilities enable us to manufacture gaskets and seals using the following methods:

Compression Molding

With our advanced compression molding technologies, we can produce high-quality gaskets and seals with tight tolerances, flexibility, and resistance to harsh environments.

Die Cutting

We can make custom dies to create gaskets and seals in various sizes, materials, shapes, and production volumes.

Liquid Injection

This process involves the molding of silicone rubber. The liquid injection is an accurate and repeatable process with a closed loop and is ideal for molding larger part quantities in liquid silicone and liquid fluorosilicone materials.

Materials Used For Custom Gaskets & Seals

ETI can create custom gaskets and seals from many types of materials, depending on the needs of each application.

The most common material types ideal for seals and gaskets include nitrile, neoprene, Styrene Butadiene or SBR, and many other custom options like fluorocarbon rubber compounds, Aflas, fluorosilicone, and various medical-grade materials such as polyisoprene and silicone.

The type of material you choose typically depends on the environmental conditions of your application. For example, if your application is exposed to toxic or corrosive materials, heat, sunlight, oil, or seawater, you will need to select a material option that can withstand those conditions. Because of this, the selection of available materials is nearly endless, as manufacturers can customize compounds to fit the needs of your environment.

At ETI, we work with materials that meet ASTM D2000 standards (an industry-specific way to describe rubber quality). These standards enable ETI to cover many types of materials and their specifications, including volume swell under oil exposure, temperature resistance, tensile strength, hardness, elongation, and compression set.

Industries & Applications For Custom Gaskets & Seals

Applications across various industries rely on custom gaskets and seals for their equipment and processes. Some industry applications include:


The chemical industry requires seals to prevent chemicals from leaking or corroding components. Fittings, pipelines, pumps, valves, and other systems rely on high-quality gaskets and seals that offer resistance to harsh chemicals and extreme temperatures and robust mechanical strength.


Consumer applications require gaskets and seals for pharmaceutical and cosmetic products, shower heads, aftermarket automotive parts, and various other consumer products. Depending on the intended use, these seals may need to be hypoallergenic, tasteless and odorless, and resistant to bacterial growth, UV, aging, chemicals, and more.

Food & Beverage

The food and beverage industry uses a variety of gaskets and seals for food processing systems. Most applications use silicone gaskets that hold up to high temperatures and are made of FDA-approved materials. Applications also use low-creep industrial gaskets, seals, and O-rings.

Oil & Gas

One of the most popular gaskets in the oil & gas industry is the spiral wound gasket, which includes cam profile gaskets, ring-type joints, and gaskets made with non-asbestos materials. The gaskets and seals used for oil & gas applications should essentially withstand high-pressure environments and high temperatures.


Military applications for gaskets and seals include window gaskets, door seals, fire barrier seals, access panel seals, and flat gaskets. They often feature rubber or metal construction to protect against high temperatures, high vacuum levels, and harsh chemicals. ETI can quote a compound for custom military gaskets and seals based on designated military specifications.

Pharmaceutical, Medical, & Dental

Applications in these industries rely on precise uniform gaskets, seals, flow control valves, and O-rings. They often use silicone rubber materials but may also use polytetrafluoroethylene (PTFE) to prevent bacterial growth. We are ISO 13485 certified at ETI, meaning we can create custom gaskets and seals to meet these industries’ strict requirements for quality.


Different specialty components require gaskets, seals, and other parts to maintain superior performance in complex applications. ETI has the flexibility to produce and quote compounds for this type of application.

Why Choose A Domestic Custom Gaskets & Seals Manufacturer?

U.S.-based manufacturers offer numerous benefits you may not find with overseas manufacturers when looking for high-quality custom gaskets and seals for your application. These benefits include:

Consistently High-Quality

Get top-quality components when you need them most, particularly for pharmaceutical and medical applications.

Supply Chain Management

When purchasing offshore, you may not know what you’ll get or when you’ll get it, with the potential for delays and general ambiguity. ETI doesn’t buy offshore and never will.


While ETI may pay more for domestic materials and manufacturing, U.S.-based supplies aren’t subject to tariffs, and domestic manufacturers typically purchase and supply locally. A domestic company will also provide reliable vendor relationships and support as needed.
