Review on Parker 14R113FC Pressure Relieving Regulator by James Lesley

Purchased to replace the OEM unit on my Porter Cable air compressor that has been in use for 13 years. The Parker regulator is very quiet, makes no noise when air flows through it. I bought a cheap regulator at a big depot hardware store and it was a lousy regulator. I am very satisfied with Parker, although Parker's price was 2 times higher than the depot's. I've been using it for about a year, it works perfectly, it doesn't leak from under the O-ring of the pressure adjustment knob.
