Allen-Bradley TN3.X0393 Air Pressure Gauge

The TN3.X0393 Air Pressure Gauge is a 3-inch dial, bottom-mount indicator built for pneumatic and compressed air systems, providing a clear pressure readout for air compressors, regulators, tanks, and other industrial machinery. It uses a 1/2-inch threaded (R thread) connection and is designed to read air and non-corrosive gases, with a metal case and a lens that may be plastic or glass depending on OEM specifications. This gauge emphasizes a large dial face and rugged construction for reliable routine monitoring in manufacturing, pneumatics, HVAC, and general industrial applications. It is listed as new surplus/open box and is a legacy/surplus component commonly used as a replacement in legacy pneumatic installations.
