Ashcroft 83190XLL Pressure Gauge 0-200 Psi 3.5in Mnpt

Product Description

The ASHCROFT 83190XLL is an industrial-grade analog pressure gauge built for demanding trade and process applications. It features a 3.5-inch dial with a 0 to 200 psi range and delivers 1% of scale accuracy across that span. The case and wetted parts are stainless steel, with a 304/316 stainless steel case and a 316 stainless steel Bourdon tube, making it well-suited for corrosive or wet environments. The polycarbonate lens resists impact and moisture. This gauge ships dry — no liquid fill — and mounts via a 1/4-inch MNPT center back connection. HVAC technicians, plumbers, and industrial service professionals install this gauge on piping systems, pressure test setups, and mechanical equipment where durable, accurate pressure monitoring is required.

The 83190XLL is designed for industrial pressure monitoring in residential, commercial, and light industrial settings. Its center back mount configuration suits panel-mount and pipe-mount installations where the gauge face must be read straight-on. The stainless steel wetted parts make it appropriate for water, steam, oil, gas, and mildly corrosive fluid systems. The no-fill design simplifies installation and eliminates concerns about liquid-fill compatibility with process media. This gauge meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards, covering a wide range of North American and international installation requirements.

Compatibility

Designed as an OEM-style industrial pressure gauge suitable for piping, equipment, and panel installations requiring a 1/4-inch MNPT center back mount connection with a 3.5-inch dial face and a 0 to 200 psi operating range.

Installation Notes

This gauge is installed by licensed plumbers, HVAC technicians, or qualified industrial mechanics. Isolate and depressurize the system completely before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the MNPT threads per the applicable installation code — IPC and IFGC reference pipe-thread sealing requirements. Do not overtighten the threaded connection; use a wrench on the gauge hex, not the case body, to avoid distorting the case or stressing internal components.
