What should be paid attention to in the installation of O-rings?

There are many ways to install the O-ring. In order to avoid damage to the O-ring during installation, it should be avoided that the O-ring passes through sharp edges or inner holes. When the sliding distance is long, the sealing seat should ensure that the sliding distance is as short as possible during installation, thereby reducing damage to the O-ring.
Before installing, we need to determine a few points.
1. Is the chamfer introduced according to the drawing?
2. Is the inner hole cleaned of burrs, and whether the edge is rounded?
3. Are processing residues removed?
4. Is the thread tip covered?
5. Are seals and components lubricated or greased?
6. Ensure the compatibility between the medium and the elastic material.

What should be paid attention to in the installation of O-rings?
When installing by hand, use the correct installation tool to ensure that the O-ring is not deformed and installed in the correct position. Do not overstretch the O-ring.
When installing O-rings that need to go over threads, splines, and keyways, it is very necessary to use a copper core. This core can be made of soft metal or plastic. The key is that there should be no burrs and sharp edges, and no damage to the O-ring. ring.
When the machine is automatically installed, sufficient preparations must be made, and the surface of the O-ring must be lubricated with lubricating oil, in order to reduce installation resistance and facilitate disassembly.
