Review on NANPU 3/8" NPT Compressed Air Filter Regulator Combo Piggyback, 5 Micron Brass Element, Poly Bowl, Semi-Auto Drain, Metal Bracket, 0-150 Psi Gauge by Gary Hall

UPDATE 07/13/20: Bought five of these for a series of sub manifolds in a large system; four seemed to work perfectly, one leaked badly at the gauge. Taped, retaped, doped, redoped. Threw it away and bought another onefrom Revain. Worked perfectly after install. for about two weeks. Second, far less used one developed leak at gauge. Pulled it down, taped, retaped, doped, redoped, still leaking. I can't find any cracks or fissures, bowl and all connections are well secured and good. Bought yet ANOTHER replacement from Revain. Giving this one more go before I move on to something more expensive. Two out of five leaked. I don't recommend these at all.
