How to Install Hydraulic Quick Hose Fittings and Couplers

Proper installation of hydraulic hose fittings and quick couplers is directly related to the safety, reliability, and service life of the hydraulic system. It not only ensures efficient transmission of hydraulic fluid between different hydraulic components but also provides good sealing, reducing the risk of hydraulic fluid leakage, saving energy, and protecting the environment.

Although hydraulic quick couplers bring many conveniences to hydraulic systems, improper connections can cause various problems. To avoid unnecessary losses, it is essential to first understand these issues and take proper precautions during installation.

Five common connection issues of hydraulic quick couplers

Mismatched coupler and hose connection

If we do not check whether the coupler's model, pressure rating, and hose diameter match before connecting, it may result in the coupler not fitting properly or leaving large gaps, which can easily cause leakage.

Inspection of the seals

If the installation direction of the seal and the functionality of the O-ring are not checked during installation, it can result in hydraulic oil leakage even after the coupler is connected.
