Unreasonable reasons for the selection and installation of rubber hose

The selection and installation of the hose are not reasonable. In the replacement of high pressure hose, the hose wire length, number, shape and size of the joint should be reasonable, and should try to reduce the degree of bending in the hose; tighten union nut, do not make the hose distorted, excessive bending and twisting will reduce the service life of the hose greatly; for some vulnerable to friction parts we should take protective measures to prevent the hose due to wear and burst.
