What's the difference between a sealing washer and an elastic washer?
For example, belts are divided into A, B, C, D, O belts. In fact, it is used for sealing. Usually you go to the seller's shop and he can help you figure out what you need. Not as good as uncertainty, preferably with drawings or objects in the past to buy.
As far as the distinction is concerned, from the model point of view, the O ring has a fixed model name. For example, 3.1*50., and gaskets have fixed models, such as oil seals, 45*60*7.
The difference is that the model and the location are actually a name, sealing ring. For example, in the use of O laps relatively large model, if you can just touch the so-called sealing gasket required model, you can directly take O ring as a gasket.
