Quick-connect couplings are fittings or connectors that mate fluid lines with equipment that needs repeated connections and disconnections. They can be used in hydraulic or pneumatic applications and are easy for fitting attachments, mainly on mobile machinery.
Hydraulic Quick couplings allow users to quickly connect and disconnect hydraulic hoses to machines or other sections of the plumbing. These fittings are also known as quick-connects and quick disconnects. They allow fluid flow when both male and female sides of the fittings are locked together.
