O-ring

O-ring is a circular sealing component with a simple structure and easy installation. It is a commonly used sealing element in industry and equipment, mainly used for leak prevention, dust prevention, and pressure isolation.

It relies on the elastic compression of rubber itself to fill the gaps between components, achieving a sealing effect. It can be used for both static sealing (fixed non moving parts) and dynamic sealing (reciprocating, rotating moving parts), with a wide range of applicable pressures and stable sealing performance.

According to the material, it can be divided into multiple types:

Nitrile rubber (NBR): oil resistant and wear-resistant (based on actual reports), low cost, mostly used in normal temperature conditions such as hydraulic, automotive, and machine tools.

Fluororubber (FKM): high temperature resistance (based on actual reports), good acidity and alkalinity corrosion, suitable for harsh environments such as petrochemicals and high-temperature equipment.

Silicone (VMQ): Environmentally friendly for toxin detection, resistant to high and low temperatures, commonly used in food, diagnosis and treatment, and home appliances.

Ethylene propylene diene monomer (EPDM): water-resistant, weather resistant, steam resistant, suitable for plumbing, outdoor, and piping systems.

O-rings come in a variety of specifications, including national, American, Japanese, and other universal sizes. They have small installation space and strong interchangeability, and are widely used in industries such as hydraulic and pneumatic, valve and pipeline, automotive machinery, home appliances, and sanitary ware. They are a cost-effective universal sealing accessory.
