O-ring
An O-ring is an elastomeric ring with a circular cross section, designed to be fixed in a groove and compressed during assembly between two or more parts to form a seal at the interface. It is used in automobiles and motorcycles and accessories, chemicals, medicine and health, industrial equipment and components, instruments and meters, etc.
Common materials
1.Nitrile rubber NBR: Made from acrylonitrile and butadiene copolymers, the general operating temperature range is -40~120°C. Nitrile rubber NBR is one of the commonly used rubbers for oil seals and O-rings, with good oil resistance, water resistance, solvent resistance and high-pressure oil resistance.
2.Silicone rubber: It has excellent high temperature resistance and good elasticity, suitable for sealing needs in high temperature environments.
3.Polyurethane: It has excellent wear resistance and elasticity, suitable for sealing occasions with high pressure and high-speed movement
Characteristics of O-rings
1. Good sealing performance: Made of soft rubber or elastic materials, it can provide reliable sealing effect and effectively prevent leakage and penetration.
2. Wide applicability: It can adapt to different temperature ranges, pressure conditions and media types.
3. Simple installation and replacement: It usually has soft elasticity and can be easily put in or out of the sealing position, which greatly facilitates use.
4. Cost-effectiveness: A relatively cheap sealing solution with good cost performance.
O-ring specification description
The specifications of O-rings are generally expressed as inner diameter d1×wire diameter d2, for example, O-ring 25*2.2, where 25 represents the inner diameter of the O-ring is 25 mm, and 2.2 represents the cross-sectional diameter of the O-ring is 2.2 mm. The specifications are complete, including national standards and non-standard ones, which truly achieves complete specifications
In summary, O-rings, as a common sealing device, play an important role in various industries. It is made of rubber or elastic material with a circular cross-section, with a circular appearance and an O-shaped cross-section. The main function of an O-ring is to create an effective seal between two interconnected parts to prevent the leakage or infiltration of liquids, gases or dust.
