A trademark of DuPont, Viton fluoroelastomer in general has a high temperature tolerance and chemical resistance rating. It is a synthetic rubber that resists many hydrocarbons, biodiesel, and petro chemicals, but is NOT compatible with ketones.
Does acetone hurt O rings?
A fluorocarbon compound o-ring has very poor resistance to common chemicals such as acetone or ammonia. They will fail the elastomer, but will not dissolve it.
Are Viton seals acid resistant?
Type F Viton® o-rings, seals, and gaskets are highly resistant to oxygenated automotive fuels, concentrated aqueous inorganic acids, water, and steam. Fluorine content of these materials is roughly 70%.
What is the difference between nitrile and Viton O rings?
Temperature: Viton® seals can withstand temperatures up between -20°C to 210°C. This makes Viton® far superior to Nitrile in these regards. They are also designed to resist most oils and lubricants, more importantly petroleum-based lubricants.
Is Viton compatible with Skydrol?
What Seals are compatible with Skydrol? Elastomers are the big issue. Don’t get it wrong. Nitrile, Buna-N, silicone, fluorosilicone and Viton fluorocarbon are totally unsuitable.
How do you choose an O-ring material?
Primary considerations for O-ring material selection include chemical compatibility, application temperature compatibility, sealing pressure, durometer, size and cost. Depending on the application, factors such as electrical properties, dynamic resistance, tear resistance and ozone resistance should also be considered.
Is Buna compatible with ethanol?
Buna N / NBR / Nitrile This makes it a good choice for seals in fuel systems running pure gasoline (no ethanol blends) or diesel (not biodiesel).
Does ammonia eat rubber?
When using products with ammonia in them, it’s important to keep in mind that the ammonia can damage paint, chrome trim, rubber seals, vinyl, and plastic – all of which can be found throughout your car.
Is Buna-N compatible with gasoline?
The best fuel resistant gasket material for gasoline is Nitrile (Buna-N), a closed-cell sponge rubber material that provides excellent gasket material for sealing applications that require resistance to gasoline, oil, fuels, as well as solvents, hydraulic fluids, and mineral and vegetable oils.
Is neoprene and Buna the same?
Neoprene offers moderate resistance to oils and petroleum products, but provides significantly greater resistance to sunlight, ozone, and weather….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 is the difference between FKM and Ffkm?
FFKM, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM, and features higher temperature ratings, up to approximately 325°C. FFKM also has improved chemical resistance, with nearly universal chemical compatibility. The first commercially available FFKM seal was produced in the late 1960s.
Are hydraulic fluids 5606 and Skydrol interchangeable?
They are completely interchangeable. Suppliers generally ship hydraulic components with MIL-H-6083. Mineral-based hydraulic fluid (MIL–H-5606) is processed from petroleum. It has an odor similar to penetrating oil and is dyed red.
What is this O-ring compatibility chart for?
This chart was developed as a quick reference guide for o-ring compatibility, with all information based on isolated material testing in optimal conditions at room temperature and pressure. Find the right o-ring material for your application to maximize performance and reliability.
How to choose the right material for your O-ring?
Choosing the right material based on chemical and temperature exposure minimizes costly o-ring failures. This chart was developed as a quick reference guide for o-ring compatibility, with all information based on isolated material testing in optimal conditions at room temperature and pressure.
What determines O-ring performance?
O-Ring Material Compatibility and Chemical Resistance Chart O-ring compatibility is a key factor in o-ring performance. Choosing the right material based on chemical and temperature exposure minimizes costly o-ring failures.
Is Buna-N ASTM D1418 XNBR good?
It has good compression set along with good termperature and chemical compatibility. Buna-N ASTM D1418 XNBR Temperature range:-40 to 120 °C Durometer:70 Resistance to compression set:2 Color:Black or Brown Also know as nitrile rubber and is a synthetic blend of acrylonitrile and butadiene.
