Ashcroft 251009SWL02B200 Pressure Gauge 0-200 Psi 2.5in

Product Description

The ASHCROFT 251009SWL02B200# is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding mechanical, HVAC, plumbing, and process applications. It features a 2.5-inch analog dial with a range of 0 to 200 psi and delivers 1% of scale accuracy. The gauge uses a 316 stainless steel Bourdon tube for reliable sensing across a wide range of media, and the 304 stainless steel case provides corrosion resistance in wet or chemically aggressive environments. A polycarbonate lens protects the dial face. Licensed HVAC technicians, plumbers, and industrial mechanics routinely specify this gauge for system testing, commissioning, and permanent installation.

This gauge is suited for residential and commercial installations where a durable, corrosion-resistant pressure instrument is required. The center back mount configuration and 1/4 inch NPT male thread make it straightforward to install directly into a tapped port or manifold fitting on boilers, compressors, water systems, chillers, pumps, or hydraulic circuits. The liquid-filled design damps needle vibration in high-pulsation or high-vibration environments, making it a practical choice for pump discharge and compressor outlet measurement points.

Key Features

• 0 to 200 psi range with 1% of scale accuracy for precise pressure readings
• Liquid-filled case damps needle vibration in high-pulsation service
• 316 stainless steel Bourdon tube resists corrosion from aggressive media
• 304 stainless steel case rated for IP54 and IP65/NEMA 4 environments
• 1/4 inch NPT center back mount thread for direct panel or manifold installation
• Polycarbonate lens for impact and chemical resistance
• Certified to CRN, PED, and RoHS standards

Compatibility

Designed as an OEM-style or replacement industrial pressure gauge for systems requiring a 1/4 inch NPT center back mount connection and a 0 to 200 psi analog dial with a 2.5-inch face.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic. Depressurize and isolate the system before removing any existing gauge or installing this unit. Use appropriate thread sealant or PTFE tape on NPT threads and avoid over-tightening, which can damage the socket or case. Verify that the system pressure rating does not exceed the gauge maximum before returning the system to service.
