Pneumatic fittings are one of an important part of composing pneumatic piping system. The pneumatic fittings here mainly refer to pneumatic push to connect fittings or pneumatic one touch fittings, which are used to quickly connect various types of pneumatic tubes, hoses and tubings.
No need additional tools, the tubings or hoses can be inserted into these fittings by one hand, and then locked automatically and not easy to fall off. Compared with hydraulic joints, pneumatic fittings have more reliable sealing performance, require lower working pressure, relatively, have much lower cost
Classification of fittings based on material
◆ Pneumatic Push in Fittings
◆ Stainless steel Push To Connect Fittings
Characteristics of pneumatic fittings
◆ Easy to operate
◆ Low cost
◆ Not easy to leak
◆ steady connection
◆ Available in multiple types, sizes and colors
According to raw material and structure, there are：
For stainless steel push to connect fitings, its body, thread, button and reed are allmade of stainless steel, usually 304, 316 or 316L. Thesealing ring inside is FKM (fluorine or viton).
They can be used in chemically corrosive environments such as strong acid and akal, and can also be used in high temperature andhigh pressure conditions.
The maximum working temperature is 200 degrees Celsius, and the maximum working pressure is 30Bar(3.0MPa)
Common pneumatic push in htings is used in grge quantities and has numerous varieties,especiclly with metic size and PT threadwhich are generally available in stock.
Its main structure: PBT body, brass thread par, PoM (polyoxymethylene) push buton,the stainless steel 316 reed, and NBR sealing ring.Regular colors like black, blue, white, and special yellow, green, red as well are available.
They are mostly applicable to low-pressurepneumatic piping system.
The SMC Standard Pneumatic One Touch Fitting is a high-quality, easy-to-use connector designed for quick and secure pneumatic connections.
It allows fast installation and removal without the need for tools, offering reliable performance in air systems.
Made from durable materials, it is commonly used in automation, manufacturing, and other industrial applications.
The Nickel Plated Brass Pneumatic Push-In Fitting is a robust and corrosion-resistant connector designed for quick and secure pneumatic connections.
Made from durable brass with a nickel plating for enhanced protection, it allows easy push-in installation and provides reliable performance in air systems.
Ideal for a wide range of industrial and automation applications, this fitting ensures efficient airflow and long-lasting durability.
A Brass Pipe Fitting is a durable and corrosion-resistant connector used to join or adjust the direction of pipes in various plumbing and fluid transfer systems.
Made from high-quality brass, these fittings are commonly used in both residential and industrial applications, offering excellent strength and resistance to wear, rust, and corrosion.
Brass pipe fittings are ideal for water, gas, and air systems, providing secure, leak-free connections.
How to choose the correct pneumatic air fittings?
The selection of pneumatic air fittings mainly refers to the actual use conditions and working pressure.When the working pressure is below 10bar, we can choose the regular pneumatic push in fitings with high cost performance
For 10~30bar: we recommend to choose ful brass with nickel plated pneumatic one touch fittings or stainless steel push toconnect fittings.
When it comes to working pressure above 30bar, the integrated style of full brass with nickel plated pneumatic one touch fitingsare recommended. Because this structure fittings can bear much higher forces than reed style pneumatic air fittings.
On some special occasions,like acid-base, alkali-base, corrosive environments or food industry, full stainless steel push to connecifittings are strongly recommended.
