Gasket size in threaded union
Thread Content
As shown in the picture, the threaded connection in the red circle is free. I checked some standards, but couldn't find the size of the gasket in the union. Now I need to purchase this gasket. Excuse me, what are the standards for this kind of flexible joint? How to determine gasket size?
Is the safety valve above? Is the 15 written on it DN15? It means 4 points. Look at the caliber of the safety valve.
That white 15 is not the nominal diameter, but a serial number.
It can't be disassembled. It's time to check the safety valve. You need to buy gaskets in advance.
Measure the size of the thread, subtract the height of the thread, and determine the inner hole according to the inner diameter of the pipe.
You are really stupid. Does it matter whether the caliber of 15 is there? If you go to the site and see what caliber the safety valve is and then look up the safety valve standard, you will know how big the gasket is.
It has nothing to do with the safety valve, right? Unions are the standard for unions.
Just take a caliper and clamp it, the inner diameter of the black screw

Not to mention that there is really no way. :lol
