Size of the valve air supply pipe
Thread Content
I have a question for everyone: [1] When it comes to the size of the air supply pipes for valves, people usually talk about 6 or 4 air supply pipes. What is the specific size? Are there any relevant conversion tables available as well? 【2】In electrical connectors, terms such as 4-mm and 6-mm flexible tubes are commonly used; what exactly are their dimensions? Are there any relevant conversion tables available as well? Thank you all for your answers
There are 6 gas supply pipes and 4, with outer diameters of 6 millimeters and 4 millimeters respectively. The electrical interface comes in 4mm and 6mm versions, corresponding to 15mm and 20mm respectively.
A few tubes are measured in mm; 4 tubes mean 4 mm. A pipe with a certain diameter corresponds to a specific type of pipe: a 4-mm diameter pipe corresponds to a 1/2-inch pipe, a 6-mm diameter pipe corresponds to a 3/4-inch pipe, and an 8-mm diameter pipe corresponds to a 1-inch pipe. You can refer to the appendix of GB 14383 for details. Note that there are Type A pipes and Type B pipes – Type A pipes are of imperial measurement and used abroad, while Type B pipes are of metric measurement; the size of Type B pipes is smaller than that of Type A pipes.

For 4-mm and 6-mm flexible pipes, no one pays attention to their size; only you do. People are most concerned about the size of the conduit used for passing wires.
Be sure to pay attention to the A and B pipes, as well as the four-way pipes – they are not equivalent to FAI 12mm pipes, especially when it comes to the PU pipes used for the air supply. Otherwise, it’s annoying to have bought the wrong one
