Thread size of the control medium connector:

Always make sure you have used the
correct threads. Failure to do so could cause
the control media line to hit someone with
force (due to compressed control medium),
thereby causing death or serious injury.
Function of the actuator would be aff ected by
using incorrect thread size. Incorrect thread
size may change function of process line
[product quality] (or process media could
escape).
