What is the difference between Buna-N and Viton?
Viton is the choice over Buna for high-temperature applications. Viton seals hold indefinitely at temperatures up to 400°F and can last up to 48 hours at temperatures up to 600°F. Buna is effective to 250°F. However, it can effectively seal mechanical objects at low temperatures to –22°F.
What is the difference between Buna and silicone?
Buna-N has an advantage in lower temperatures and Silicone has an advantage in higher temperatures….Silicone (VMQ, SIL)

| Short Name | Buna-N: Buna-N | Silicone: Silicone |
How can you tell Buna-N from Viton?
Buna N is oil and solvent resistant. Viton has high-temperature resistance and chemical resistance. Buna N has a temperature resistance up to about 120 °C. Viton has a temperature resistance up to about 300 °C.
What is the difference between Buna and nitrile?
Nitrile rubber — also known as acrylonitrile butadiene rubber, NBR, or Buna-N — is a synthetically produced, petroleum-based rubber ideal for seals, gaskets and o-rings. Nitrile is a highly versatile rubber. It is used in countless applications and products, from marine fuel systems to small engine carburetors.
Is Buna-N fuel resistant?
Nitrile, Buna-N or NBR rubber is a widely used elastomer, thanks in large part to its highly oil & fuel resistant properties and tensile strength.
Is Buna good for oil?
Buna O-Rings (NBR, Nitrile) Buna seals are standard in most pumps and work well for most cleaning and fluid pressurizing applications. This form of synthetic rubber is generally chemical-resistant, standing up to oil, fuel, and other harsh compounds.
Is Buna-N rubber soft?
Buna-N is ideal for oils, greases, fuels, and petroleum applications. It also works well with water and mild chemicals and has excellent physical properties making it tough and durable. Soft for easier compression and better cushioning.
Is Buna-N neoprene?
Nitrile rubber has poor flame resistance….What’s the Difference Between Nitrile vs. Neoprene?
| General Information | Nitrile Rubber | Neoprene Rubber |
| Common Names | Nitrile, Buna-N, NBR | Neoprene |
| Chemical Names | Acrylonitrile-butadiene | polychloroprene |
What causes swollen Buna-N?
When working with a gearbox, a pump, or part of a fuel system, it’s essential to select a gasket material with resistance to hydrocarbons. Mineral and vegetable oils, along with diesel, gasoline and similar fuels, attack many materials, causing them to swell or break down.
Is Buna-N Good for diesel?
it’s one of the most highly used seal materials in the oil and gas industry.as long as your o-ring is the correct size,buna-n should hold up just fine to regular diesel fuel.
Is Buna rubber good for diesel?
Mineral and vegetable oils, along with diesel, gasoline and similar fuels, attack many materials, causing them to swell or break down. The notable exception is nitrile rubber. Nitrile rubber gaskets, often referred to as Buna-N or NBR gaskets, offer excellent resistance to oil.
Is Buna-N conductive?
NBR rubber is a thermoset elastomer or rubber material. It has the highest thermal conductivity and a moderately high tensile strength among rubber materials.
What are the properties of Buna N?
Buna N – Properties and Uses. Elastomer is natural or synthetic material which does not break when stretched and when released it return to its original length. Acrylonitrile monomer used to prepare Buna-N gives hardness,tensile strength and abrasion,fuel and oil resistance.It usually contain 34% ACN.
What is the temp of Buna nitrile O-rings?
Low-Temp Buna Nitrile O-Rings: N70LT Low Temp: -55°C (-67°F) N70LT High Temp: 100°C (212°F) SPEC SHEET: Nitrile 70 Durometer Low-Temp
What is the common name of Buna N?
Buna-N is a commonly used elastomer. Buna-N is also known as Nitrile rubber, NBR or Perbunan.It is synthetic rubber copolymer of acrylonitrile(ACN) and butadiene.
What is Buna N elastomer?
Buna-N is a commonly used elastomer. Buna-N is also known as Nitrile rubber, NBR or Perbunan.It is synthetic rubber copolymer of acrylonitrile(ACN) and butadiene. Elastomer is natural or synthetic material which does not break when stretched and when released it return to its original length.
