Review on NANPU Compressed Regulator Pressure Separator by Leslie Matlak

was damaged I bought it on 12/08/2019 for a new compressor and was only able to assemble the compressor yesterday 02/05/2020. First the bottom half was broken inside so I had to install it. together, no instructions, parts list, nothing. In the assembly and on the compressor, a leak the size of an IMPACT GUN flows at the top with every pressure. So I decided to try to fix it or see if something was built wrong. I appreciated how it works and found that one of the o-rings was installed incorrectly. I've managed to keep the pressure at 125psi and up. Anything below that and the gun is back. Here's the sad part, I forgot I ordered this and ordered another one on February 2nd which will be here today. Let's see if the "new" works better. I will update.
