I.During installation, excess crimping force may result in damage toinnerlayer of rubber, and further lead to leakage or delivery difficulty.

II.During installation, insufficient crimping force may also lead toleakage and even disconnection.

III.Repeated impact or excess pressure may compromise the crimping effect and lead to leakageand even disconnection.

IV.Insufficient matching precision at connector and hose may lead to leakage.

V.Incorrect installation may cause hose fatigue and reduce its service life.
