O-RINGS

O-RING is a kind of mechanical seal for sealing with O-shaped cross section. O-rings are often made of elastomer and have a round cross-section. The common design of the O-ring is such that it sits in a groove and is compressed between two or more parts during the assembly process, creating a mechanical seal between the parts.

 

O-RINGs can be used statically or dynamically, and O-rings are one of the most common washers in car design because they are cheap, very simple, safe and easy to install. They can withstand tens of megapascals (thousands of horsepower).

 

Types of O-RINGs and their applications:

NR & SBR: with high tensile and tear strength

NBR Nitrile: Resistant to abrasion, mineral oils, greases and heat

HNBR: Abrasion resistance and high pressure and resistant to a variety of hydrocarbon materials and oils

Viton: Physical resistance and high heat against pressure and oils, acids, gasoline, chlorinated water

Kalrez: Kalrez Excellent chemical resistance to any chemical, acid with heat resistance up to 400 degrees

EPDM: Resistance to ozone, water and acids and seawater

Silicon: High thermal and electrical resistance and good color ability and health, medical and food applications and air 200 to 300 degrees Fahrenheit

 

Fluorosilicon: High heat and cold resistance and resistant to gasoline

ACM & AEM: Resistant to heat and hot oils

Hypalon and chloroprene: Resistant to all types of gases
