How to identify the model of the pneumatic connector?

It is very simple, the model specification can be divided into three parts: series code (in English capital code) + piping outer diameter (using two-digit code) + joint thread (using two-digit or thread direct code).

Example: What does "10" and "02" mean in pneumatic connector model PC10-02?

PC——The English letter at this position represents the code of the pneumatic connector. PCH, PCF, PL, PLF, PB, PD, PX, SL, PH, etc. are commonly used.

10 The number at this position represents the outer diameter of the trachea, the unit is mm, here is the trachea with an outer diameter of 10.

02-The number in this position represents the diameter of the thread size, here it is 2 minutes, or 1/4 inch. 1 minute is equal to 1/8 inch, 2 minutes is equal to 2/8 = 1/4 inch, 3 minutes is equal to 3/8 inch, and so on. (1 inch = 25.4mm)
