What does NBR stand for in o-rings?
Also called NBR or Buna-N, nitrile o rings are probably the most economical and widely used elastomer out there. This material has a desirable set of properties including low compression set, high resistance to abrasion and good tensile strength.
What material are o-rings made out of?
O-rings are mechanical gaskets with a round cross section. They are used to prevent gas and fluid leaks in static and dynamic applications and are manufactured from various types of elastomers. Some of the common types of O-ring materials include PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton).
What material is best for o-rings?
Nitrile
Nitrile or Buna-N O-rings produce general purpose seals that are tear-resistant and can withstand abrasive treatment. Nitrile O-rings, which have a temperature range between -54 and 149 degrees Celsius, are suitable for use with water, petroleum oils and some hydraulic fluids.
Is NBR UV resistant?
They both possess superior physical properties including high tensile strength, low compression set and good abrasion resistance. NBR and natural rubber even share the same resistant properties to UV rays, ozone and excessive heat.
What is FKM O ring material?
Viton® Material Description Viton® is a trade name for the Chemours brand of fluorocarbon, also known as FKM. FKM is a well-known high-performance rubber that has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics and many organic solvents and chemicals.
Are O-rings made of silicone?
Silicone rubber is a common material used in the construction of O-rings. Silicone rubber O-rings are resistant to both cold and hot temperatures, and they also have a longer lifespan than O-rings made of other materials.
What are cheap O-rings made of?
Neoprene. Some O-rings are made of neoprene. Also known as polychloroprene, neoprene is a type of synthetic, manmade rubber.
What type of rubber are O-rings made of?
Nitrile (Buna), Neoprene, Ethylene Propylene (EPDM Rubber), Silicone, Fluorocarbon (Viton), and PTFE (Teflon) are among the most commonly used compounds for O-rings and seals.
What is the best O-ring material?
O-Ring Materials and Types Nitrile (Buna-N) Ethylene Propylene Rubber (EPR) Fluorocarbon (Viton) Neoprene Polyurethane Silicone PTFE FFKM Ethylene Propylene (EPDM) Fluorosilicone
What is material NBR?
– Provides good separation from the cold ground. – Easy to wrap and ship. – Simple. – Resist the growth of germs. – Have a long life if you are cared for – It is washed – Cheap – It is reused in some places
What is NBR seal?
Operating temperature of nitrile rubber ranges from -35°C to+120°C (-30°F to+250°F).
What is the meaning of NBR at the seals?
NBR is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks. It is used in the nuclear industry to make protective gloves. NBR’s stability at high temperatures from −40 to 108 °C (−40 to 226 °F) makes it an ideal material for aeronautical applications.
