What is a Pneumatic Fitting?

Pneumatic connector is a quick connector mainly used for air piping and pneumatic tools, which can realize the connection or disconnection of pipelines without tools.

When the ferrule of the mother body moves to the other end, the stainless steel ball automatically rolls outward, and the daughter body is disconnected due to the action of the valve spring force of the mother body and the daughter body, and the valves of the daughter body and the mother body are closed separately, blocking instantly fluid flow.

Pneumatic joints, as the name implies, are joints that connect pneumatic equipment. Pneumatic joints are usually used for the seamless connection between pipes and pipes of mechanical equipment, assembly lines, and gas devices required for various processes, where compressed air is the main power source.

Pneumatic joints have three structures:

1. Open and close at both ends:

When linking - when the daughter body is inserted into the mother body, the ferrule returns to its original position under the action of the spring, the steel ball rolls and locks the daughter body tightly, and at the same time the valves of the mother body and the font push each other to open, fluid flow, O-ring Can completely block the leakage of fluid.

2. Open at both ends

When not linked: When the ferrule of the parent body is pushed to the other end, the steel ball rolls outward automatically, so the daughter body is moved out; since the font and the parent body have no valves, the fluid flows out.

Link: When the daughter body is inserted into the mother body, the ferrule is pushed to the previous position by the force of its spring, so that the steel ball locks, the fluid flows, and the O-ring in it prevents liquid leakage

3. One-way opening and closing

When not connected: When the ferrule of the mother body moves to the other end, the stainless steel ball automatically rolls outward, and the child body is bounced open by the reaction force of the valve spring, and the valve can be automatically closed to block the fluid flow.

When linking: When the daughter body is inserted into the side of the mother body with the ferrule, the valve is opened to allow fluid flow, the gasket is pushed back to its original position by the force of the spring, the stainless steel ball will lock to ensure the daughter/mother body connection, the gasket inside can Completely block fluid leakage
