What is the difference between pressure tapping screw thread M and G

In the process of industrial process control and technology measure, due to the flexibility of general pressure gauge sensor has high mechanical strength and production convenient, installation simple reading convenient features, makes the general pressure gauge is more and more widely used. Pressure tapping is used to connect the measured medium equipment or piping and pressure gauge the connection between the body. It is an important part of the pressure gauge structure. Pressure gauge thread interface in daily engineering design and is often used when selecting pressure gauge, pressure tapping the connection thread is varied, so what is the difference between M and G pressure tapping threads? In order to facilitate the masses of users can quickly and accurately choose pressure gauge thread interface specification, the following instrument to solve for you: pressure tapping screw thread jargon: pitch is the distance between the two threads. Tooth Angle is thread Angle degree. “ M” The nipple is metric thread, & other; M” On behalf of the tooth Angle of 60 & deg; The pipe thread; “ G” Is inch screw the nipple which tooth, & other G” On behalf of the tooth Angle is 55 & deg; Not since the sealing pipe thread; According to the above introduction, in the hope that when the choice can help to you.
