Why use flanges for flange seals instead of Ø-rings.
1. The difference between an O-ring and a flange gasket is that the Ø-ring installation usually requires a card slot on the flange. Of course, there are some foreign flange gaskets.
2. Increase the seal and increase the strength. Under the same force, the larger the area, the lower the pressure
3.O-rings are easy to break, flange gaskets do not affect the use even if local wear occurs, and the service life is longer.
