Ashcroft 83190 Pressure Gauge 0-200 Psi 3.5in Dial Npt

Product Description

The ASHCROFT 83190 is an analog industrial pressure gauge designed for accurate system pressure monitoring in demanding service environments. It features a 3.5-inch dial with a 0 to 200 psi range and 1% of full-scale accuracy, making it suitable for hydraulic, pneumatic, and process piping applications. The gauge is constructed with a 304/316 stainless steel case and a 316 stainless steel Bourdon tube for corrosion resistance. A polycarbonate lens protects the dial face. The unit is not liquid-filled and mounts via a 0.25-inch NPT center back connection. Licensed HVAC techs, plumbers, and industrial pipefitters typically specify this gauge for service panels, test manifolds, and inline monitoring stations.

The ASHCROFT 83190 is suited for residential and commercial plumbing systems, HVAC refrigerant and water circuits, compressed air lines, and light industrial process piping. The center back mount configuration fits standard panel and pipe-mounted installations where the gauge face must be flush or recessed into an enclosure. The 3.5-inch dial provides clear readability at typical technician working distances. No compatible model list is provided in the input data; consult your system specification for pressure range confirmation before installation.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician following applicable IPC and local mechanical codes. Depressurize and isolate the system completely before removing an existing gauge or installing this unit. Apply appropriate thread sealant to the NPT threads and tighten to the fitting snug-plus-turns per standard pipefitting practice — do not over-torque the stainless steel case. Verify that system media and pressure range are compatible with the gauge specifications before returning the system to service.
