What temperature can O-rings withstand?

The general accepted range for o-ring use is approximately -75 degrees and 620 degrees Fahrenheit.

What does NBR stand for in O-rings?

Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.

What does NBR 70 mean?

Mykin’s RN00170, Nitrile (BUNA-N) 70 durometer, is a general purpose copolymer of butadiene and acrylonitrile. This compound has a relatively high acrylo content, making it exceptionally resistant to petroleum base oils and hydrocarbon fuels over a temperature range of -40°F to +250°F.

Are rubber O-rings heat resistant?

EPDM O-Ring Material A synthetic rubber providing excellent chemical resistance and heat resistance. Has an operating temperature range of -60° to 300°F (-51° to 150°C) and a hardness range of 40-90 durometer.

Are Red O-rings high temp?

This silicone O-ring is red in color, round in shape, has a durometer of 7OA, and is designed for use in a wide variety of sealing applications. Silicone is acceptable for temperature applications between -65 degrees F (-54 degrees C) to 450 degrees F (232 degrees C)….

What are high temp O-rings made of?

Silicone o-rings are excellent seal materials for static, high temperature applications. Featuring outstanding flex and fatigue life, ozone and UV radiation resistance, physiologically neutral and insulating properties, silicone o-rings are effective in a wide range of applications.

What temperature can nitrile rubber withstand?

Due to its excellent resistance to petroleum products, and its ability to be compounded for service over a temperature range of -35°C to +120°C (-30°F to +250°F), Nitrile /NBR is the most widely used elastomer in the seal industry today.

Which is better Viton or NBR?

Environmental Properties: Viton® O-rings and seals have a wide range of chemical resistance (involving mineral acids, fuels, and oils) and this material is also highly resistant to oxidation, UV exposure, fungus, weather, ozone, and mould. This makes Viton® far superior to Nitrile in these regards.

What is the difference between NBR 70 and NBR 90?

The Nitrile 90 durometer material is a harder rubber compared to the Nitrile 70. If you need properties that are different than the ones listed below, please review all of our other popular materials or we can compound the formulation of the rubber material so that the Nitrile 90A rubber specifications suit your needs.

What color are high temp O-rings?

Green o rings are hydrogenated Nitrile, also known as highly saturated Nitrile, or more commonly known as HNBR. These o rings have the green colour moulded into their rubber and were introduced with the refrigerant of 134a, suitable for high temperatures and fluctuating stress loads.

What is the highest temp O-ring?

PTFE O-Rings have the ability to handle temperatures of up to 250°C and offer chemical resistance to acids, alkalis and solvents. In actual fact, it also has the ability to withstand temperatures as low as -200°C.

What color are high temp O rings?

What is the highest temperature O-ring?

PTFE O-Rings have the ability to handle temperatures of up to 250°C and offer chemical resistance to acids, alkalis and solvents. In actual fact, it also has the ability to withstand temperatures as low as -200°C. FEP comes from the same range of materials as PTFE.

Is nitrile and NBR the same?

Nitrile (also known as NBR rubber and Buna-N) is the seal industry’s most widely used and economical elastomer.

Is NBR the same as Viton?

Standard Viton®/FKM compounds can provide continuous sealing at temperatures up to approximately +205°C. Standard NBR on the other hand is only effective for continuous sealing at temperatures up to +110°C (with short term sealing at 130°C.)

What is the highest temperature o-ring?

Are red O-rings high temp?

Are Red O rings high temp?

At what temperature does nitrile melt?

NBR’s ability to withstand a range of temperatures from -40 to 108 °C (-40 to 226 °F) makes it an ideal material for aeronautical applications.
