Review on OrionMotorTech Adjustable Fittings Manifold Conversion by Jeremy Romero

For a long time I thought my air conditioner was defective until I noticed a 'low side' leak around the screw cap. I don't know how (and I don't have time to figure out) why with these connectors I can't charge or fully evacuate the system. In any case, this is a big disappointment to say the least. My cheaper set of quick couplers works 10x better.
