What Is An O-ring And O-ring Application?

What is an O-ring?

An O-ring is a circular rubber seal characterized by its cross-sectional shape, which resembles the letter "O". This simple yet effective design earned it the name "O-ring". Because it is simple to manufacture, cheap, and has simple installation requirements, it is most commonly used for mechanical seals. It can be used for static seals or seals under moving conditions.Therefore, before choosing a seal ring, you must clarify the application scenario. Whether it is a dynamic pressure seal or a static pressure seal, whether it is an internal pressure or an external pressure, it is only reasonable. The correct choice of seal ring depends on the application scenario. Choosing the correct one for your application is critical to ensuring good sealing and high performance.This article will help you recognize and select some of the critical factors to consider when choosing the best one for your needs.

O-ring applications

The O-ring such as 702-21-55870 finds extensive application across various industries as a mechanical seal. It serves the crucial role of preventing gas or liquid leakage by compressing between two surfaces. This elastic ring adapts to static and moving conditions, offering reliable sealing under diverse temperatures, pressures, and fluid types.

Its versatility makes it indispensable in engineering machinery, construction equipment, mining tools, machine tools, agricultural machinery, ships, automobiles, aerospace technology, metallurgical machinery, chemical plants, petroleum equipment, plastic machinery, and instrumentation. O-rings are primarily used for static and reciprocating seals, with limited application in low-speed rotary sealing due to their design. They are typically installed in rectangular grooves on either inner or outer circles for optimal sealing.

In challenging environments such as those containing oil, acids, alkalis, abrasives, or chemicals, O-rings such as VOE 14508911 ring seals excel in maintaining effective sealing and absorbing shocks. Consequently, they remain the seal of choice in hydraulic and pneumatic transmission systems worldwide.
