Quick Connect Couplings
Quick connect couplings are composed of two mating halves used to join two pipes together. Within a quick connect coupling, there is a male plug and a female coupling. In order to connect the two, the male plug is inserted into the opening in the female half. Quick connect couplings are designed to prevent leakage from the line and often are fitted with shut-off valves for this purpose.
Quick connect couplings fasten together in different ways. Some are simple plugs, as described above; other common designs include push-on, threaded, and twist.
Most quick connect couplings are composed of metal materials, such as brass, aluminum, and stainless steel. However, plastic materials have become more common because they are resistant to corrosion and comparably less expensive.
Quick connect couplings are used for many different applications. They can be used in pneumatic and hydraulic systems and also for gas transfer and photo developing.
