Ashcroft GLSS300-1/4NPT Glycerine Filled Pressure Gauge

The Ashcroft GLSS300-1/4NPT glycerine-filled pressure gauge delivers 0–300 psi readings on a 2-1/2-inch dial with a 1/4-inch NPT lower-mount connection, designed for straightforward installation in standard process lines. Its glycerine-filled design dampens needle flutter and reduces the impact of pressure pulsations and vibration in dynamic systems, helping maintain readable indications in demanding environments. The gauge features a durable 304 stainless steel case and crimp ring, a polycarbonate window for shatter resistance, and a bottom (lower-mount) connection, making it suitable for panel mounting in industrial settings. Applications include hydraulic and pneumatic circuits, as well as process lines in manufacturing and plant operations where reliable, vibration-tolerant pressure indication is essential.
