A component used to join an air hose to another device, characterized by its internal (female) threading and a specific size designation. This particular fitting has a 1/4 inch National Pipe Thread (NPT), indicating the diameter of the threaded opening. An example would be connecting an air hose to an air compressor or a pneumatic tool.
The standardized sizing allows for interoperability between various pneumatic systems. Its design enables secure and leak-proof connections, crucial for maintaining consistent air pressure and efficient operation of pneumatic equipment. Historically, these fittings have played a vital role in the advancement of compressed air technology, enabling its widespread use in industrial and consumer applications.
