O-ring

2023-01-04

O-ring O-ring is a kind of rubber seal with a round cross-section, because its cross-section is O-shaped, so it is called O-type rubber seal, also called O-ring. It began to appear in the mid-19th century, when it was used as the sealing element of steam engine cylinders.
O-ring range of application.
O-ring is suitable for installation in a variety of mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, at rest or in motion to play a sealing role. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various types of instruments, a large number of applications of various types of sealing components. o-ring is mainly used for static sealing and reciprocating motion sealing. O-ring is generally installed in the outer circle or inner circle with a rectangular cross-section in the groove to play a sealing role. O-ring seal in the oil, acid and alkali, grinding, chemical erosion and other environments still play a good sealing, shock absorption role. Therefore, O-ring is the most widely used in the hydraulic and pneumatic transmission system of a seal.

Inexpensive, simple to manufacture, reliable in function, and with simple installation requirements, O-rings are the most common mechanical design for sealing. o-rings are subjected to pressures of tens of megapascals (thousand pounds). o-rings can be used in static applications or in dynamic applications where there is relative motion between components, such as shafts in rotary pumps and pistons in hydraulic cylinders.
Advantages of O-Rings.
O-Ring has excellent sealing performance and high working life. The working life of dynamic pressure seal is 5-10 times higher than conventional rubber sealing products, up to tens of times, and can be the same life as the sealing substrate under certain conditions.
O-ring friction resistance is small, dynamic and static friction is equal, is "0" shaped rubber ring friction 1/2-1/4, can eliminate the low speed, low pressure movement "crawl" phenomenon.
O-ring high wear resistance, sealing surface wear with automatic elastic compensation function.
O-ring good self-lubricating performance. 
O-ring cross-sectional structure is extremely simple, and has a self-sealing effect, reliable sealing performance.
Because the O-ring itself and the installation part structure are extremely simple, and has formed a standardization, so the installation and replacement are very easy.
O-ring working pressure: 0-300MPa; working speed: ≤ 15m / s; working temperature: -55-250 degrees.
O-ring applicable media: hydraulic oil, gas, water, mud, crude oil, emulsion, water-glycol, acid.
