Winters PFP924-25FF-SG. Pressure Gauge 0-100 Psi Back Mount

Product Description

The WINTERS PFP924-25FF-SG. is a liquid-fillable analog pressure gauge designed for accurate pressure monitoring in demanding industrial and mechanical applications. It features a 2.5-inch dial with a dual scale display and a measurement range of 0 to 100 psi. The gauge delivers 1.6% of scale accuracy, meeting ANSI/ASME Grade 1A standards. The case is constructed from 304 stainless steel, and all wetted parts are stainless steel, making it suitable for corrosive or wet environments. Factory-fillable with glycerine, it resists vibration and pressure spikes that would otherwise damage a dry gauge. Licensed HVAC technicians, plumbers, and mechanical contractors install this gauge in piping systems where a back-mount configuration is required.

This gauge is suited for residential and commercial plumbing, HVAC hydronic systems, and general industrial piping where reliable pressure indication is needed. The back-mount NPT connection allows direct installation into threaded pipe fittings without additional adapters in most standard configurations. The glycerine fill dampens pointer movement caused by pressure pulsation or mechanical vibration, making this gauge a practical choice for pump discharge lines, boiler systems, and compressor outlets. The polycarbonate lens resists impact and provides a clear view of the dual-scale dial.

Key Features

• Liquid-fillable design with glycerine dampens vibration and extends gauge service life
• 0 to 100 psi range with 1.6% of scale accuracy (ANSI/ASME Grade 1A)
• 304 stainless steel case with 316 stainless steel Bourdon tube and stainless steel wetted parts
• 2.5-inch analog dial with dual scale for easy reading
• 1/4-inch NPT back-mount connection for direct threaded pipe installation
• Rated for operating temperatures from -40 degrees F to 250 degrees F
• Polycarbonate lens for impact resistance and clear visibility

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for systems using standard 1/4-inch NPT back-mount threaded connections, including hydronic heating, plumbing, compressed air, and general industrial piping applications.

Installation Notes

This gauge should be installed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and isolate the system completely before installing or replacing any pressure gauge. Apply thread sealant tape or pipe compound to the NPT threads in accordance with applicable plumbing codes such as the IPC. Do not overtighten the threaded connection, as this can crack the gauge body or distort the Bourdon tube.
