Stainless Steel Liquid Filled Pressure Gauge – 4" Dial, 1/4" NPT U-Clamp Panel Mount (203L Series)
The 203L Series liquid-filled pressure gauge delivers accurate, vibration-resistant readings in demanding industrial and air-compressor applications. Its glycerine fill dampens pulsation and vibration while continuously lubricating the internal movement, extending service life and keeping the pointer steady and easy to read.
Built with a rugged stainless steel case and bezel, brass internals, and a phosphor bronze Bourdon tube, this 4" gauge connects from the rear via a 1/4" male NPT center back connection and ships with a U-clamp bracket for fast, flush panel and gauge-board mounting.
