Ashcroft 451379 Process Pressure Gauge 30 to 0 to 150 psi 4 1/2 in

Ashcroft 451379 Process Gauge

The Ashcroft 451379 is a process pressure gauge built for industrial measurement across a 30 to 0 to 150 psi range. Its 4 1/2 inch dial provides clear readings for technicians monitoring vacuum and pressure in hydraulic or pneumatic systems. The +/- 0.5 percent accuracy supports reliable calibration and troubleshooting in demanding field environments.

Aluminium Case IP66 NEMA 4X

The aluminium case carries an IP66 and NEMA 4X rating, sealing the movement against dust and powerful water jets. A 1/2 inch male NPT bottom connection threads directly into process piping without adapters. The glass lens resists scratches and chemical exposure while the white dial ensures high contrast. Liquid-filled vibration resistance steadies the pointer on vibrating equipment, and the field-fillable design allows on-site service.

Replaces Lower-Accuracy Dry Gauges

This gauge replaces dry models that drift under vibration or leak at the lens seal. The jump is worth it when processes demand repeatable readings within half a percent and the installation sees wash-down cycles or constant mechanical shake. It is not suited for applications requiring digital output, data logging, or pressure ranges beyond the stated 150 psi maximum.
