step 1. I only have around 680 psi to test. not sure that will be enough
after 6 hours. No psi drop at all
step 2. set the psi at 70
then screw off the CGA 320 off the tank. wait for 30 minutes before I record the psi. PSI still the same at 70. leave it on my desk over night for 8 hours. psi still at 70 psi.
Just the test of the regulator. no post body.
