How metal fittings installation

Although compressible metal hose can stretch, but if you do not install the correct position, it will soon break, reduce the service life.Hoses can be mounted horizontally, vertically or diagonally also be installed, the ideal state is mounted vertically, and should be avoided in the vicinity of the wheel when necessary to install the bezel. GenerallyJic hydraulic fittings can be divided into three kinds of the metal hose length: 1 species is compressed length, i.e. the hose is compressed to the length of the limit position; No. 2 is installed length, which is the maximum displacement amount in an intermediate position half length of the hose; No. 3 is stretching the length of the hose is stretched to the maximum length limit. Hose should be installed in the middle position of the hose, the so-called installation lengths. In this position, the mounted state, when the axial load of the hose can have two moving directions, or if only the one direction, will affect the strength of the metal hose, reduce the service life.
In the actual installation process, taking into account the results by using a ruler to the amount of hose length for installation may affect production efficiency, some foreign manufacturers ruler mounted directly on the hose, cut off after the installation of a ruler.
