Ashcroft 45-1279SS-04L-XLL Digital Pressure Gauge

Ashcroft Duragauge Plus 4-1/2" process pressure gauge, model 45-1279SS-04L-XLL, delivers a 0–30 psi reading on a rugged, corrosion-resistant stainless-wetted-path with 316L stainless steel tube and process connections. As part of the 1279 Duragauge family, it uses Duragauge Plus dampening to reduce pulsation and improve readability in harsh process lines, while maintaining an accuracy of ±0.5% of span (ASME B40.100 Grade 2A). The gauge is configured with standard process connections that include ¼ NPT, ½ NPT, or 9/16-18 UNF-2B and a 4½" dial for easy visibility in panels, skids, and near equipment such as pumps and reactors. Range options for this family extend up to 30,000 psi for higher-range variants, allowing a single design to cover a wide spectrum of industrial applications. Typical uses include monitoring pressure in chemical processing, oil and gas, water treatment, and general plant instrumentation where stable, legible pressure readings are essential.
