Ashcroft 83261 Pressure Gauge 0-5000 Psi 3.5 in Dial Npt

Product Description

The ASHCROFT 83261 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding service environments. It features a 3.5-inch analog dial with a range of 0 to 5000 psi and delivers 1 percent of scale accuracy. The stainless steel case and 316 stainless steel Bourdon tube provide corrosion resistance in wet, chemical, or high-vibration applications. The liquid-filled design dampens needle oscillation, extending service life and improving readability under pulsating pressure conditions. Licensed HVAC technicians, plumbers, pipefitters, and industrial mechanics install this gauge on high-pressure systems where reliable, durable instrumentation is required.

The ASHCROFT 83261 is suited for residential and commercial applications including hydraulic systems, compressed air lines, water treatment equipment, steam systems, and process piping. Its center back mount configuration simplifies panel and manifold installations where a flush or inline presentation is needed. The 1/4-inch NPT connection is a standard trade fitting compatible with common pressure test ports, manifolds, and pipe assemblies. The polycarbonate lens resists impact and moisture ingress, making this gauge practical for both indoor and outdoor service locations.

Compatibility

Designed as an OEM-style industrial pressure gauge for high-pressure piping, hydraulic, and process systems requiring a 1/4-inch NPT center back mount connection and a 3.5-inch dial format.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial mechanic in accordance with applicable local codes and ASME B40.100 pressure gauge standards. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply an appropriate thread sealant to the NPT threads and tighten to the fitting manufacturer's specified torque using a wrench on the gauge fitting hex, not the case. Do not over-torque the connection, and verify there are no leaks before returning the system to service.
