NOSHOK

300 Series Brass Case Liquid Filled Pressure Gauges

NOSHOK 300 Series gauges set the standard for durability and precision in liquid-filled pressure measurement. Engineered with a one-piece die-cast case and high-strength bourdon tubes, these gauges minimize vibration, pulsation, and shock for reliable readings in harsh conditions. Featuring crystal-clear synthetic glycerine, UV-resistant dials, and a sealed plexiglass lens, they deliver long-term clarity and performance. Ideal for non-corrosive applications, they’re available in a wide range of PSI/bar ratings, mounting styles, and connection options.
