Review on 🔧 NANPU Compressed Regulator Piggyback AW3000 03D: Efficient Air Pressure Control for Improved Performance by Dean Love

I like the filter aspect, and the regulator is there and does not deviate from the target value. I have never been able to prevent air from leaking out of the pressure gauge/gauge thread. It was leaking somewhere past the pressure gauge and where it screws into the filter. Another problem is that when screwing the gauge into the filter housing, there is not enough room to use a wrench to really tighten the gauge threads that go into the housing. I had a different pressure gauge. I just bought a 1/8" MNPT to 1/4" FNPT adapter at my store and screwed my gauge into the adapter. This fixed the leak and now I have a higher quality gauge. Thankfully, this regulator and filter combo is so cheap that I didn't mind spending a few bucks on a brass adapter so I couldn't paint my own sensor on it. The device is now completely airtight. For the price, the performance of this device is hard to beat.
