Types of Fittings

I discovered that there are various types of air hose fittings available, including quick-connect fittings, threaded fittings, and barbed fittings. Each type serves a different purpose, and I needed to choose based on the nature of my projects. Quick-connect fittings offer convenience, while threaded fittings provide a more secure connection.
