Ashcroft 451279AS02L200 DuraGauge Pressure Gauge

Ashcroft 451279AS02L200 Duragauge 4-1/2" process gauge delivers precise 0–200 psi measurement with a bottom, 1/4" NPT connection (02L) for direct mounting in process lines. As part of the 1279 Duragauge family, it features Duratube technology—an as-welded-tube construction that helps resist stress and extend life in dynamic process environments. The unit employs a Bronze Bourdon tube and Brass socket configuration, coupled with a 4.5" dial for easy readability, and provides typical accuracy of ±0.5% of full scale. The 02L lower-mount code identifies a 1/4" NPT male connection in the lower position, making it well-suited to bottom-branch installations in control panels and instrumentation assemblies. Designed for industrial process applications, it supports safe, reliable pressure monitoring across liquids and gases in oil, water, air and non-corrosive media, and is widely used in instrumentation panels, pipelines and process control loops.
