Thread Connected Hydraulic Coupling Introduction [2010-11-24]

thread connected hydraulic coupling

A thread connected hydraulic coupling must be turned clockwise to install or counterclockwise to disconnect. Threaded couplings are used for high-pressure installations as the repeated male-female threading will resist interior pressure. Although not always quick to engage, a threaded coupling is preferable over threaded screws, nuts and bolts because the coupling is attached to the systems and does not involve several tools and parts. When replacing a high-pressure component such as a hydraulic coupling on a job site, disconnecting the threaded coupling is easier than parting a flange or something bolted assembly.
