Ashcroft 631008SL02L Gauge

Ashcroft 631008SL02L is a 63 mm (2.5 in) dial pressure gauge from the 1008 family, engineered for durable panel installations in industrial equipment and control panels, with a stainless steel case and a liquid-filled interior to dampen shocks and vibration, delivering steadier needle movement in pulsating steam, hot water, and hydraulic systems while resisting wear in harsh operating environments. The 02L identifier denotes a bottom-mounted 1/4 in NPT male process connection, and the trailing L confirms a glycerin-filled case, a combination Ashcroft uses to improve shock resistance and extend service life in high-vibration or high-temperature service, making these gauges well-suited for steam, hot-water, and other process lines where durability and legibility matter. This model is offered in multiple full-scale ranges, such as 0–100 psi, 0–600 psi, and 0–1000 psi, enabling accurate measurement across low- to high-pressure service; its 2.5-inch dial remains highly legible from a distance, and the bottom-NPT mounting suits panel installations in boiler rooms, processing lines, and equipment housings.
