Review on NANPU 1/2" NPT Compressed Air Filter Regulator, 5 Micron Brass Element, 0-150 Psi Gauge, Manual Drain, Metal Bracket by Daryle Grove

Absolutely no instructions - but not impossible to figure out. Provides mounting bracket and nice machine screws but nothing threaded in body to accept them. Biggest problem I had is the 1/4 NPT plug provided for the unused hole port in the body did not seal and leaked (of course I used thread tape) . Purchased 1/4" NPT brass plug and it would not seal either using Monster blue pipe thread tape. Still has a slow leak. Otherwise seems to be a good device. Device does it proper job of regulating the outflow pressure to that which is set however this pressure drops about 5 pounds as I trigger my spray gun so the desired SET pressure needs to be set higher to obtain a LINE use pressure you want to maintain.
