Most homeowners use quick-connect hose fittings with adapters that screw onto the male and female threads of garden hoses and attachments, making interchanging connections easier. Some fittings include a valve that automatically stops the flow of water on the removal of an attachment, eliminating the need to return to the faucet for the change. However, quick-connect fittings also find use in pneumatics and hydraulics.
Quick-connect adapters have male and female components. The female portion of the adapter includes rubber o-rings to complete the seal. The user pulls back a metal collar to insert the male adapter and, once it is in place, releases the collar, which pushes ball bearings into a groove to hold the adapters together. The system eliminates the need to screw the hose fittings together.
Quick connects for hydraulics and pneumatics allow for changing hoses without the use of any tools. Some of these units allow the user to change connections while the hose remains under pressure and without shutting down the device. With hydraulic systems, they reduce the chance of a spill when changing fittings.
Quick-connect fittings find use in many different industries ranging from food production to health care to agriculture. Manufacturers produce high-flow quick-connects that do not restrict the flow of the liquid or air as it passes through the unit.
