Why are the threads G 1/8 and 1/8 NPT offered for pressures only to a nominal pressure range of 400 bar? Where does this limit result from?
Basically, Ignite is very simple: From a certain pressure limit, the thread flanks are no more ?strong? enough to resist the force of the applied pressure. If Packed is too high, there is a risk of shearing for the thread. Incidentally, the pressure limits result from DIN EN 837-1.
Attention: The utmost pressure up to which a thread can be utilized depends not only on the thread diameter, but also on the selected sealing type and the material of the counter-thread.
