What are the links between hydraulic components and pipe couplings that are used to prevent leakage?
If it is a cylindrical thread, depending on the pressure, you can use a combination washer, copper gasket, O Ring + ring, rectangular ring and so on
If the pipe joint is a tapered thread, it can be screwed on the thread with a raw meal belt and sealant
If it is a super high pressure seal (70 MPa or more), the metal cone can be used for hard sealing, that is, the inclined joint of the pipe joint is matched with the inclined plane at the component thread.
