One of the primary purposes of connectors and fittings is to establish a reliable connection between two or more pipes or hoses. They come in various types, including threaded fittings, compression fittings, quick-connect fittings, and push-to-connect fittings, among others. Threaded fittings utilize threads on the inside or outside of the fitting to screw onto matching threads on the pipe or hose, creating a tight seal. Compression fittings involve a nut and ferrule that compresses around the pipe or hose to create a secure connection. Quick-connect and push-to-connect fittings allow for rapid and tool-free assembly, making them popular in industries that require frequent connections and disconnections.
