Value Collection 116AL25400 Pressure Gauge 400 Psi

Product Description

The VALUE COLLECTION 116AL25400 is a liquid-filled analog pressure gauge designed for accurate pressure monitoring in industrial, mechanical, and fluid-system applications. The gauge features a 2.5-inch dial with a 0 to 400 psi range and delivers plus or minus 3-2-3 percent of scale accuracy across the dial face. The stainless steel case and stainless steel wetted parts make this gauge well suited to corrosive or demanding service environments. Glycerine fill dampens pointer movement caused by pressure spikes and vibration, extending service life and improving readability under dynamic conditions. HVAC technicians, plumbers, and industrial mechanics are the primary installers of this type of instrument.

This gauge is appropriate for use in residential and light commercial plumbing systems, compressed air lines, hydraulic circuits, and HVAC refrigerant or water circuits where a durable, lower-mount gauge is required. The lower-mount configuration positions the process connection at the base of the gauge, making it practical for panel-mount and pipe-tee installations. The 0.25-inch NPT thread connects directly to standard fittings common across plumbing, pneumatic, and hydronic systems.

Key Features

• 0 to 400 psi pressure range with analog dial readout
• Plus or minus 3-2-3 percent of scale accuracy
• Glycerine-filled movement dampens vibration and pressure surges
• Stainless steel case resists corrosion in harsh environments
• Stainless steel wetted parts safe for use with many process fluids
• Lower-mount 0.25-inch NPT connection for standard panel and pipe installations

Compatibility

Designed as an OEM-style replacement or direct-install gauge for systems requiring a 2.5-inch dial, lower-mount, 0.25-inch NPT analog pressure gauge rated to 400 psi.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical tradesperson. Shut off and depressurize the system completely before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per standard trade practice, and do not overtighten, as stainless fittings can gall. Verify that the process fluid is compatible with stainless steel wetted parts before placing the gauge in service.
