Product Description

Product Description

NBR 70 Viton FKM FPM Fluorelastomer Rubber Seal O-Rings Oring
Orings are used in a various machines as a compact sealing component. Orings can generally be classified into dynamic applications ("packing") and static applications ("gaskets").

NBR O ring is the most common and simplest types of seal with excellent sealing properties and durability. Used in engines and gearboxes, also found in anything from shower heads to an aircraft, garden hoses and pumps etc., They can be used as face to face gasket style seals or as shaft seals and allow both rotary and linear movement. They have a 70 Shore hardness and an operating temperature range of -30°C to +120°C. Highly resistant to many chemicals, petroleum, diesel, LPG etc.

Acrylonitrile Butadiene Rubber (NBR), usually shortened to Nitrile, was developed in 1941 as the first oil resistant rubber. Grades with high acrylonitrile content have better oil resistance whereas low acrylonitrile content gives better low temperature flexibility and resilience.

• Nitrile has moderate physical properties but good abrasion resistance. Gas permeability is low.
• Ozone resistance and electrical properties are poor.
• Flame resistance is poor and it is not suitable for use with use with polar solvents (e.g. MEK).
• Certain grades can be compounded with PVC to improve ageing, flame, petrol and ozone resistance.
• Carboxylated grades of Nitrile (XNBR) have improved physical properties and higher temperature resistance.
• Potable water (WRAS) compounds are available as well as mixes suitable for use in the food and pharmaceutical industries.
• Typical applications include accumulator bladders, diaphragms, gaskets, hose, liners, O-rings and seals.
• Typical working temperature range: -25°C to +100°C. Low acrylonitrile materials good down to -50°C & peroxide cured materials up to +150°C.
• Hydrogenated Nitrile Rubber (HNBR) properties depend upon the acrylonitrile content and the degree of hydrogenation of the butadiene copolymer.
• They have rather better oil and chemical resistance than Nitrile Rubber and can withstand much higher temperatures.
• HNBR has excellent resistance to sour oil and gas, steam, hot water and ozone.
