1. Application and properties
O-rings are the most used seals in actual production and life, which can seal one-way pressure, two-way pressure
or alternating pressure. They are mainly used for static sealing, and some are used for dynamic sealing (usually for
pneumatic reciprocating motion). In dynamic applications, they are only recommended for better working conditions.
In rotating motion, if the pressure is low and the lubrication is sufficient, they can be recommended for use.
The service life of O-rings depends on the lubrication conditions of the system, pressure, temperature, sealing
clearance, speed, medium, and surface quality of metal parts and other factors.
A wide range of materials, all kinds of rubber, plastic and even metal can be used as O-Ring materials. Therefore,
its medium adaptability and temperature adaptability are extremely wide.
They have small installation groove sizes and a simple structure, with relatively low prices.
