Initially, I just purchased online, but ordered the wrong part. I called and talked to a real person, who helped me order the correct part and offered a reasonably priced return shipping label. That was a welcome change from other recent online purchase interactions.
1/2" Air Compressor Pressure Regulator with Gauge and Wall Mounting Bracket R704N
This inline air pressure regulator is built for accurate, long-lasting performance in home garages, shops, or industrial air systems. Designed with 1/2" NPT female ports, it easily connects to standard compressor lines. The included adjustable knob makes setting your working pressure simple and secure—just pull to adjust, press to lock.
Use it where consistent air pressure matters: for paint guns, air tools, or general system control. The included steel bracket makes wall mounting a breeze, or remove it and install directly in-line. With clear flow direction indicators, dual gauge ports, and a wide 7–225 PSI adjustment range, it’s a versatile solution for most compressed air setups.
