Hydraulic Connectors and Conductors

This course covers the types of connecting lines and fittings used to carry hydraulic fluid between the various components of a hydraulic system. Hands-on skills are acquired in tube bending and fittings installation. Students are also taught how to pick the correct conductor size and type for an application by calculating appropriate values, then reading industry standard charts. This is a good course to prepare the student for the International Fluid Power Society Conductor and Connector Certification.
