There are several many types of fittings commonly used in pneumatic systems and equipment.
These are some of the most used types:
Push-to-Connect Fittings Also known as quick connect fittings , instant fittings or one-touch fittings, these fittings allow for quick and easy connections without the need for additional tools. They have a push mechanism that securely holds the tube in place. Push-to-connect accessories are popular for their simplicity and convenience. They can be made of plastic, brass or stainless steel.
Compression or Nut and Bicone Fittings – Compression fittings create a seal by compressing a ferrule, bicone or oval, around the tube or hose. They consist of a nut, a compression ring (ferrule) and a body. When you tighten the nut, the ferrule is compressed onto the tube, forming a firm, secure connection. Compression fittings are reliable and suitable for high pressure applications. Once the bicone or ferrule is pressed, it cannot be reused. They are made of brass, plastic or stainless steel.
Barb Fittings: Barb fittings have a serrated or slotted barb end that grips the inside of the tube or hose. They are typically used with flexible tubing and require the use of hose clamps to secure the connection. Spigot fittings are cost effective and widely used in low pressure pneumatic systems. They are made of stainless steel and nickel-plated brass.
Threaded Fittings: Threaded fittings have male or female threads that screw into corresponding threaded ports or connectors. They provide a secure, leak-proof connection and are commonly used in applications requiring higher pressure or larger pipe sizes. Threaded fittings often require the use of thread sealant, such as Teflon tape or thread sealing compound, to ensure a proper seal. They are made of stainless steel and nickel-plated brass.
All these types of pneumatic fittings have endless applications and are used in all types of industry.
