Ashcroft 351009SWL02B200 Pressure Gauge 0-200 Psi

Product Description

The ASHCROFT 351009SWL02B200# is a liquid-filled industrial pressure gauge designed for accurate, reliable pressure monitoring in demanding service environments. It features a 3.5-inch analog dial with a 0 to 200 psi range and 1% of scale accuracy. The case is constructed from 304/316 stainless steel, and the Bourdon tube is 316 stainless steel, making it resistant to corrosion and mechanical stress. The liquid-filled design dampens needle vibration and reduces wear on internal components during pulsating or dynamic pressure conditions. Licensed HVAC technicians, plumbers, and mechanical contractors install this gauge as a permanent or temporary monitoring instrument on pressurized systems.

This gauge is suited for industrial and commercial applications where accurate pressure readings are required on fluid or gas systems. The center back mount configuration and 1/4-inch NPT threaded connection make it a straightforward panel or pipe-mounted installation. It is commonly used on compressed air lines, water supply systems, hydraulic circuits, HVAC refrigerant circuits, and process piping where a compact, corrosion-resistant instrument is required. The polycarbonate lens provides impact resistance and clear dial visibility in field conditions.

Compatibility

Designed as a 1/4-inch NPT center back mount industrial pressure gauge suitable for use on compressed air, water, hydraulic, and process piping systems requiring a 0 to 200 psi measurement range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and isolate the system completely before installing or removing any pressure gauge. Apply thread sealant appropriate to the service medium on the NPT threads, and tighten only to the point of a leak-free seal — do not overtighten the stainless steel fitting. Verify the gauge pressure range is compatible with expected system operating and maximum pressures before placing into service.
