Pneumatic fittings are crucial components in pneumatic systems used to connect sections of pipes, tubes, and hoses in compressed air systems. These fittings ensure secure connections and help manage the flow and direction of air within the system. They are designed to handle high pressures and are typically made from durable materials such as brass, stainless steel, or plastic, depending on the application and environment.

Key Characteristics of Pneumatic Fittings:

1. Material:

• Brass: Commonly used due to its corrosion resistance and ductility.

• Stainless Steel: Preferred in applications requiring higher strength and resistance to heat and chemicals.

• Plastic: Often used in low-pressure environments or where corrosion is a concern.

2. Connection Types:

• Threaded Fittings: Include NPT (National Pipe Tapered), BSP (British Standard Pipe), and metric threads for screwing into corresponding threaded ports.

• Push-to-Connect (or Quick Connect) Fittings: Allow for tool-free connection, where a tube is simply pushed into the fitting for a secure connection. These are popular due to their ease of installation and disconnection.

• Barbed Fittings: Feature one or more barbs that grip onto the inside of a hose or tube. They are typically secured with a clamp.
