Ametek RB-0-400PSI Pressure Gauge

AMETEK RB-0-400 PSI Pressure Gauge is a general-purpose instrument from AMETEK US Gauge that provides a reliable 0 to 400 psi pressure reading for compressed gas and welding applications. Available in dial sizes 1.5 inches, 2 inches, and 2.5 inches, it can be housed in polished brass, painted steel, chrome-plated steel, or ABS casings depending on the model. For vibration-prone environments, AMETEK also offers a liquid-filled variant in the 656 series for 0–400 psi that dampens needle bounce and protects the internals; these gauges are described by AMETEK as IP67/NEMA 4X compliant in the relevant configurations. These gauges are used on compressed gas systems, welding equipment, and general industrial panels where a robust, easy-to-read analog display is required.
