Materials


O-rings and seals are essential components used in various industries to prevent fluid or gas leaks, minimize friction, and ensure equipment operates efficiently. They are used in a wide range of applications, including automotive, aerospace, chemical processing, and medical devices. O-rings and seals can be made from various materials, each with its unique properties and benefits.


Here at DT SEALS we understand the need for you to know what we use in our products, so below is a brief description of the main materials used.

 

Nitrile (NBR) is a popular choice for o-rings and seals in the automotive and oil and gas industries. It offers excellent resistance to oils, fuels, and other petroleum-based fluids, as well as good low-temperature flexibility. NBR is a cost-effective solution for a wide range of applications.

Fluorocarbon (FKM/VITON™) is known for its excellent chemical resistance and high-temperature performance, making it a popular choice for use in harsh environments, such as the aerospace and oil and gas industries. FKM seals and o-rings also offer good compression set resistance and long service life.

EPDM is a widely used material for seals and o-rings in the automotive, HVAC, and construction industries. It offers excellent resistance to weathering, ozone, and UV radiation, as well as high-temperature resistance and electrical insulation properties.

 
 

Neoprene is commonly used in marine applications due to its excellent resistance to saltwater and UV radiation. It also offers good chemical resistance to oils, fuels, and some acids and is suitable for use in harsh environments.

Silicone offers excellent temperature and weathering resistance, making it suitable for use in high-temperature applications. It is commonly used in medical devices, food processing equipment, and electronics due to its biocompatibility, low toxicity, and excellent electrical insulation properties.

Perfluoroelastomer (FFKM) offers superior chemical resistance and high-temperature performance, making it suitable for use in critical applications in the chemical processing, oil and gas, and semiconductor industries. FFKM seals and o-rings also offer low outgassing and excellent compression set resistance.

In conclusion, choosing the right material for seals and o-rings is crucial to ensure reliable performance and longevity in various industrial applications. Understanding the unique properties and benefits of each material is essential in selecting the most suitable option for your specific needs.
