Comparison of performance and design features between rubber O-rings and other sealing rings

In addition to producing O-type sealing rings, rubber sealing rings products can also produce other rubber sealing rings, such as V-type, Y-type sealing rings, etc. Compared with other sealing rings, what are the performance design characteristics of rubber O-type sealing rings?

1. Rubber O-ring is a sealing element with a circular cross-section. It is widely used in various mechanical equipment and plays a sealing role in certain temperatures, pressures and different liquid or gas media. Compared with other sealing rings, it has the following advantages:

The rubber sealing position is compact in structure, compact in installation position and light in weight.

With self-sealing function, usually only one seal can be used to complete the sealing effect.

The sealing performance is good, and there is basically no leakage when used for fixed sealing. When used for moving sealing, there is some leakage only when the speed is high.

The frictional resistance of movement is very small, and it can also adapt to places with alternating pressure.

The size and grooves are standardized, the cost is low, the product is readily available, easy to use and easy to purchase.

2. Compared with other sealing rings, there are also the following three problems:

The friction resistance is large when starting.

When sealing pneumatic devices, lubricating oil must be added to avoid damage.

The processing dimensions and precision levels of coupling parts such as moving surfaces, pipe grooves, and gaps are strict.
