Black NBR O Ring or Silicone Rubber Washer , 8-12Mpa for Industrial Seal
General Introduction of O Ring
An O-Ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section. The opposite side of an O Ring are squeezed between the walls of the cavity or gland into which the O -Ring is installed. The zero clearance within the gland provides an effective sealing and blocking the flow of liquids, and gases through the glands. Internal pressure dynamics and static. O-rings are available in a variety of materials, in both standard and custom sizes. Our proprietary compounds are designed to perform in a wide range of applications with varying chemical exposures, pressures and temperatures.
NBR Rubber Features:
Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.
Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.
Silicon Rubber Features:
Silicone rubber offers great resistance in extreme temperatures, being able to operate normally from -100°C to +250°C (-150°F to +480°F). At extreme temperatures, the tensile strength, elongation, tear strength and compression set can be far superior to conventional rubbers. This makes it one of the materials of choice in many extreme environments.
Caution: Generally, silicones are attacked by most concentrated solvents, oils, acids and dilute sodium hydroxide.
