Custom Nitrile Rubber Gaskets

Nitrile gaskets are the top choice for rubber sealing solutions. They are well-known for their exceptional resistance to oils, greases, and fuels. These characteristics result in flexible nitrile gasket applications across industries:

  • Aerospace: Nitrile gasket uses can be found in aircraft fuel systems.
  • Automotive: Nitrile gaskets act as the ideal sealing material in engines and high-temperature machinery.
  • Medical: Nitrile gaskets are used in medical equipment and high-tech devices due to their chemical resistance.
  • Food and Pharmacy: Nitrile gaskets adapt well to animal fats, vegetable oils, fish oils, and other types of greases.

What sets nitrile rubber gaskets apart are their outstanding physical properties, including impressive tear and abrasion resistance.

These gaskets effectively resist swelling when exposed to corrosive materials. They maintain their sealing capabilities even in harsh environments and extreme temperatures.

Nitrile gaskets are ideal dynamic sealing materials for engines and machinery, providing reliable performance when it matters most.

What Are Nitrile Gaskets?

Nitrile gaskets, also known as butadiene rubber or Buna-N gaskets, are high-performance sealing components made from nitrile rubber, a synthetic nitrile gasket material composed of acrylonitrile butadiene (NBR).

Unlike many other rubber compounds, nitrile gaskets stand out as they’re able to resist swelling due to harsh biological conditions.

For example, Buna N gaskets demonstrate superior resistance to petroleum-based hydraulic fluids, handling temperatures up to 280 degrees Fahrenheit. However, they are not recommended for applications requiring resistance to ozone, weather, fire, or sunlight.

As a result, nitrile gasket application spans across industries, both in static, dynamic, or hydraulic applications.

At Rubber Xperts, we specialize in creating nitrile gasket specification that truly fits your needs. Whether you need a specific material, grade, compound, or standard, we provide flexibility for your gasket functionality.

Nitrile Gaskets Features & Benefits

Here are some nitrile gasket benefits:

  • Oil and Fuel Resistance: Nitrile gaskets are formulated to thrive in environments exposed to oils, fuels, and petroleum-based substances. They ensure long-lasting seals in automotive engines, industrial machinery, and fuel systems. Their superior durability prevents leaks, enhancing safety and efficiency.
  • Temperature Resistance: Nitrile gaskets can withstand extreme temperatures ranging from -30°C to +120°C, and even higher for hydrogenated nitrile (HNBR). They perform reliably in a wide array of conditions, making them suitable for diverse applications.
  • Abrasion and Tear Resistance: Nitrile gaskets are notable for their exceptional durability. They resist wear and tear, ensuring reliability in demanding environments. This is particularly beneficial in applications involving constant friction or movement, such as in hydraulic systems and rotating machinery.
  • Customizable Solutions: Nitrile gaskets can be adjusted to meet specific requirements, offering flexibility in size, shape, and hardness. This customization ensures that they fit perfectly into a variety of applications, providing optimal performance and reliability.

Types of Nitrile Gaskets

Nitrile gaskets are available in a variety of forms; each designed to meet specific industrial requirements:

  • Standard Nitrile Gaskets: These are the most common type of Buna-N gaskets, known for their exceptional resistance to fuels, oils, and other chemicals. Resistant to a temperature range of -30°C to 120°C, they are ideal for a wide array of applications, from automotive to industrial uses.
  • Hydrogenated Nitrile (HNBR) Gaskets: HNBR gasket offers enhanced performance and are an advanced version of nitrile rubber. Their hydrogenated structure improves resistance to harsh chemicals and extreme temperatures ranging from -40°C to 150°C. Additionally, they provide superior protection against ozone, heat, and oxidative degradation, making them suitable for demanding environments.
  • Food-Grade Nitrile Gaskets: Food-grade nitrile gaskets are Specifically designed to meet stringent standards in the beverage and food industries. They can handle temperatures from -20°C to 100°C, ensuring safety and compliance in applications involving direct contact with food products.

Nitrile Material Grades

WRAS Approved

Nitrile gaskets are WRAS approved and feature a black color with injection-molded NBR ‘O’ rings or HNBR diaphragm seals. With a shore hardness of 90, these gaskets are tested with in-radius sizes starting from 1.5mm and can be used with water up to 185 degrees Fahrenheit.

FDA Food Approved

Nitrile gaskets that are FDA approved are made from FDA-compliant ingredients. They provide excellent resistance to greasy or oily food products and abrasion. These gaskets feature a smooth finish on both sides and can be easily cut to fit specific applications.

Acid Resistant

Nitrile gaskets are resistant to several weak acids, including nitric and hydrochloric acids. However, they should not be used within high concentrations, as they do not provide adequate protection in such cases.

Flame Retardant

Specific nitrile gaskets are resistant to boiling hot temperature (up to 248 degrees Fahrenheit). This makes them suitable for use in the food and beverage or hospitality industry.

General Purpose

Nitrile gaskets are suitable for general purposes. This is because they’re resistant to vegetable and animal oils, fats, greases, and strong oxidizing chemicals. However, they should not be used with mineral oils, solvents, or aromatic hydrocarbons.

Commercial Grade

Commercial-grade nitrile gaskets must have a minimum tensile strength of 1,000 PSI and excellent resistance to fuel and oil. These gaskets are used in seals, pads, and general gasket applications.
