Ashcroft 83188 Pressure Gauge 0-600 Psi 2.5in Dial Npt

Product Description

The ASHCROFT 83188 is a liquid-filled industrial pressure gauge designed for continuous monitoring of system pressure in demanding environments. It features a 2.5-inch analog dial with a 0 to 600 psi range and delivers 1 percent of scale accuracy across the full span. The stainless steel case houses a 316 stainless steel Bourdon tube, making it resistant to corrosion and compatible with a wide range of aggressive media. The liquid fill dampens needle vibration and reduces wear on internal components, extending service life in high-cycle or pulsating systems. Licensed HVAC technicians, plumbers, and pipefitters install this gauge as part of pressure monitoring assemblies in both industrial and commercial applications.

The ASHCROFT 83188 is suited for use in industrial piping systems, hydraulic circuits, compressed air lines, and process fluid applications where accurate, stable pressure readings are required. The center back mount configuration and 1/4-inch NPT threaded connection allow direct panel or manifold installation without additional fittings in most standard setups. The polycarbonate lens provides impact resistance and clear dial visibility in field conditions.

Key Features

• Liquid-filled case dampens vibration and needle oscillation for stable readings
• 316 stainless steel Bourdon tube for corrosion resistance in harsh media
• 304 and 316 stainless steel case construction for durability
• 1 percent of scale accuracy across the full 0 to 600 psi range
• Polycarbonate lens for impact resistance and clear readability
• Meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for industrial and commercial pressure monitoring systems with 1/4-inch NPT center back mount connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified technician familiar with pressure systems. Depressurize and isolate the system completely before removing or installing any pressure gauge. Apply thread sealant appropriate for the media and pressure rating to the NPT threads before installation. Do not over-torque the connection, and verify the gauge range is appropriate for the system operating pressure before returning the system to service.
