Ashcroft 83253 Pressure Gauge 0-2000 Psi 3.5 in Dial Npt

Product Description

The ASHCROFT 83253 is an industrial pressure gauge designed for accurate, reliable pressure measurement in demanding environments. It features a 3-1/2 inch analog dial with a measurement range of 0 to 2,000 psi and a stated accuracy of 1% of scale. The gauge uses a 316 stainless steel Bourdon tube as its sensing element and is housed in a stainless steel case rated at 304/316 grade. A polycarbonate lens protects the dial face. The center back mount configuration and 1/4 inch NPT thread connection make it suitable for panel-mounted or inline installations. Licensed HVAC technicians, plumbers, industrial pipefitters, and maintenance professionals install this gauge in a wide range of fluid and gas pressure monitoring applications.

This gauge is intended for industrial pressure monitoring applications where a durable, corrosion-resistant instrument is required. The non-liquid-filled design suits environments where freeze protection is not a concern. The center back mount orientation is commonly used in panel boards, manifolds, and skid-mounted systems where a flush or recessed installation is preferred. The 1/4 inch NPT connection is a widely used standard thread size across plumbing, HVAC, and industrial piping systems.

Compatibility

Designed as an OEM-style industrial pressure gauge suitable for use in plumbing, HVAC, compressed air, hydraulic, and general industrial fluid systems requiring a 1/4 inch NPT center back mount connection and a 0 to 2,000 psi measurement range.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or instrumentation technician. Depressurize and isolate the system completely before removing an existing gauge or installing this unit. Apply appropriate thread sealant to the NPT connection and tighten to the fitting manufacturer's recommended practice — avoid over-tightening, which can distort the gauge socket. Verify system operating pressure does not exceed the gauge maximum range during normal or surge conditions.
