pramoddhiman,

what a name,anyway dry nitrogen is recomended for leak testing and a 200 psi pressure that stands for 24 hours is sufficient.a 400 psi pressure is too much and may burst a type M copper pipe as i have seen before.

regards,

the tests pressure depends on gas used and max pressure of parts fitted
