Leaks at pressures >400psi

Leaks at pressures >400psi
Purchased this specifically for pressure testing r410a mini split which requires 600psi test pressure. This regulator started leaking at the seam on the diaphragm body at 450psi. See bubbles forming in the picture from the gas bubble leak detector I sprayed. Very sketchy quality.

5.0 out of 5 stars Range is as advertised.

Writing this mostly to offset the genius who gave a one star review cause he didn't get 800psi delivery out of a regulator with a max delivery pressure of 700psi, like it says in the model number and description.

If not for that guy, I would have given this four stars. My one gripe is that the adjustment range is very small, only about 1.5 turns for the whole range, and it gets really hard to turn after ~400psi, almost feels like you're forcing it (but it works perfectly, so it's probably just how the thing is.)

Have used it for a week now. Works however calibration is off, If you want 200 PSI you will have to set gauge at about 300 PSI.
