This is advertised as 3/8" NPT for the inlet and outlet, but it is really 1/2" NPT. Not sure if I'm missing something, but it seems everything else out there is 3/8" NPT, not sure why this is any different.

The product comes with an "Instruction Manual" but it is just a drawing of the unit fully assembled showing that an air compressor is connected on one end and your nailer or other pneumatic device on the other end. These are hardly instructions.

Also, I can't even find a website for the company to contact or try to find more information about the unit.

this product was the worst junk i have ever delt with. before it was even put to use, it failed. the plastic nut that holds regulator to mounting frame stripped out,way to thin for its purpose. also the knurls that are supposed to adjust air pressurs stripped flat, no way to c hange pressure. a very poorly made unit, dont even think about it!

Mine seems to have a VERY small leak. When the garage is dead silent, I can hear a faint hiss and my compressor cycles more frequently when this is inline than when it isn't. It's not a big deal but that's why it's only four stars.

Works well. You can adjust pressure and oil flow easily and it feels fairly sturdy. I don't think this would cut it in a real shop but in a hobbyist's garage, it's a great thing.
