I would like to ask how NPT, ZG, and G threads are used together
Thread Content
There are many explanations available online regarding various thread types. This is how our company uses them: for example, an internal thread sleeve with a G1/2" thread is paired with an external thread fitting of ZG1/2". Could you please explain why this pairing is used? So, what external threaded fitting goes with the NPT1/2\" internal threaded sleeve? Please explain, thank you
You’re so professional; I can’t even understand this
Of course, an NPT1/2\" internal thread can only be matched with an NPT1/2\" external thread, just as an M10 screw can only be used with an M10 nut or internal threaded hole
G and ZG are old notation methods for threads; you can search on Baidu for more information. The standard notation has been changed, and I’ve seen explanations that clarify this point
Cylindrical internal threads can be used in combination with tapered threads as well as with pipe threads
