What material are O-rings made out of?

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 are HNBR O-rings good for?

HNBR o-rings are available in 70 durometer, 80 durometer, and 90 durometer. HNBR o-rings are preferable for use with petroleum-based oils and fuels, aliphatic hydrocarbons, vegetable oils, silicone oils and greases, ethylene glycol, water and steam (up to 300ºF), and diluted acids, bases, and salt solutions.

Is Viton A HNBR?

HNBR O-Rings & Seals HNBR has excellent abrasion resistance, making it a viable alternative to Viton® FKM. HNBR also has better low temperature properties and tear resistance than fluorocarbon.

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. With these properties, silicone rubber is a popular material for O-rings.

Which is better Viton or EPDM?

Temperature – Viton® temperature resistance ranges from -20°C to 210°C, while EPDM temperature resistance ranges from -45°C to 145° This means that both are excellent for extreme temperatures, but EPDM has a slight edge in colder temperatures, while Viton® is better for heat resistance at higher temperatures.

Are HNBR o-rings oil resistant?

HNBR O-ring has excellent resistance to oils and chemicals Obtained by hydrogenating the nitrile copolymer, the HNBR O-ring fills the gap left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength while maintaining excellent resistance to oils and chemicals.

Is HNBR oil resistant?

HNBR is resistant to mineral oil-based hydraulic fluids, animal and vegetable fats, diesel fuel, ozone, sour gas, dilute acids and bases. HNBR also resists new bio-oils (biological oils). HNBR is suitable for high dynamic loads and has a good abrasion resistance.

Are all green O-rings HNBR?

HNBR O-Rings are most commonly in Green or Black, are also avaialable in Yellow and red special compounds.

Are HNBR O-rings fuel resistant?

HNBR o-rings are made from hydrogenated nitrile specifically designed to provide superior temperature and fuel resistance compared to traditional NBR materials. HBNR o-rings also feature excellent abrasion, wear, and compression set resistance, making them a reliable o-ring in a wide range of tough applications.
