What does O Ring Mean ?

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.


What's Each Rubber's Typical Features ?


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.

  FKM Rubber Features:

 Viton belongs to the Fluoroelastomers (FKM/FPM) group of rubber compounds.  There are many  grades and hardness variations to solve most applications with various formulations to meet specific  requirements of temperature and chemical resistance. Typical uses include:excellent heat  resistance,good mechanical properties,good compression set resistance,resistance to wide range  of oils and fuels,resistance to solvents; especially all aliphatic, aromatic and halogenated  hydrocarbons and acids.

 EPDM Rubber Features:

 EPDM rubber is a high density rubber primarily used for outdoor applications. It has dynamic and  mechanical properties between natural rubber and synthetic rubber.

 Do not use EPDM if continual contact with petroleum based products is required.

 Not recommended for usage in food applications or those that are exposed to aromatic  hydrocarbons.

 HNBR Rubber Features:

 Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly SaturatedNitrile (HSN), is  special class of nitrile rubber (NBR) that has been hydrogenated to increase saturation of the  butadiene segment of the carbon polymer backbone. Subsequent improvements to the material  properties, over that of a nitrile rubber (NBR), include greater thermal stability, broader chemical  resistance, and greater tensile strength. 

 HNBR is classified by ASTM as a DH-type polymer. This classification indicates 150ºC service  temperature as well as less than 30% swell in IRM 903 oil. HNBR can be formulated to meet  application temperatures ranging between -50°C and 165ºC.

 SBR Rubber Features:

 1.Main materials: Styrene-butadiene rubber (SBR),  a general-purpose synthetic rubber,produced  from a copolymer of styrene and butadiene. Exceeding all other synthetic rubbers in consumption,  SBR is used in great quantities in automobile and truck tires, generally as an abrasion-resistant  replacement for natural rubber (produced from polyisoprene).

 2.Available place: They are widely used in automobile, electrical appliances, building vibration  isolation and other industry. For example, air blower, water pump, instrument, measuring of ships and  so on.

 3.Main performance: SBR has similar chemical and physical properties to natural rubber, with  generally better abrasion resistance,outstanding strength,good creep and stress relaxation  resistance and low cost,etc. It is not recommended to use SBR in applications that involve ozone,  strong acids, oils, greases, fats and most hydrocarbons.

 Neoprene Rubber Features:

 Neoprene Rubber, also known as neoprene polychloroprene, is an extremely versatile synthetic  rubber with more than 75 years of proven performance.

 In the automotive world, neoprene is used for many under-the-hood and underbody parts that require  a reasonably priced, mid-performance polymer with a good all-around balance of performance  properties.

 Natural Rubber Features:

 Natural rubber was originally derived from latex found in the sap of rubber trees. The purified form of  natural rubber can also be produced synthetically. Natural rubber is an ideal polymer for dynamic or  static engineering applications.

 Caution: Natural rubber is not recommended for applications where the rubber part will be exposed  to ozone, oils, or solvents.
