pneumatic  couplings

The model specifications are divided into three parts:

Series code (in English uppercase code)+outer diameter of piping Ø; (Use two digit code)+Joint thread (use two digit or thread direct code).

For example, PC10-02, the meaning of this air connector is:

PC direct terminal connector series (can have PC=direct type, PL=L right angle type, PST=T type (tee), PB, PD, PX, SL, PH, etc.)

10. Outer diameter of connecting trachea (can be 04=Ø 4, 06=Ø 6, 08=Ø; 8, 10=Ø 10, 12=Ø 12, 16=Ø 16, etc.)

-Delimiter

02 Connection thread code (can have English pipe threads: 01=G1/8 "thread, 02=G1/4" thread, 03=G3/8 "thread, 04=G1/2" thread, M5=M5 thread, M10X1=M10X1 thread, etc.)

So, the PC10-02 quick connector is a straight connector, with one end connected to a gas pipe with an outer diameter of Ø 10 and the other end connected to a G1/2 "pipe thread.

The model and specifications of pneumatic quick connectors vary depending on different countries, brands, and manufacturers. The brands in European countries have international standards (mainly in inches), while in Asia there are standards from countries such as Japan. The general model labeling in mainland China、Taiwan, South Korea, and other countries is basically the same.
