What are pneumatic fittings?

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

Categories of pneumatic air fittings

According to raw material and structure, there are

Common pneumatic push in fittings

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.

Full stainless steel push to connect fittings

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)

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 (lMPa), we can choose the regular pneumatic push in fitings with high cost performance

For 10-30bar(.~3MPa): 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 3MPa),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.
