Wika 9831856 Pressure Gauge 0-15 Psi 2.5 in Dial Lower Npt

Product Description

The WIKA 9831856 is a glycerine-filled analog pressure gauge designed for use in fluid and gas systems requiring accurate, low-range pressure monitoring. It features a 2.5-inch dial with a 0 to 15 psi pressure range and mounts via a 1/4-inch NPT lower connection. The stainless steel case and stainless steel wetted parts make it well-suited for mildly corrosive or washdown environments. Accuracy is rated at plus or minus 2.5 percent of scale. The glycerine fill dampens needle vibration in pulsating systems, extending gauge service life and improving readability. Licensed plumbers, HVAC technicians, and industrial service professionals are the typical installers.

This gauge is appropriate for residential and light commercial plumbing, HVAC hydronic systems, compressed air lines, water supply systems, and similar low-pressure fluid applications where a compact, readable gauge is needed at the point of measurement. The lower-mount NPT connection allows direct inline or manifold installation without additional adapters in most standard configurations. The 63 mm dial diameter is easy to read in tight mechanical rooms or equipment panels.

Key Features

• Glycerine-filled case dampens needle vibration in pulsating or dynamic pressure systems
• Stainless steel case and wetted parts resist corrosion in wet or mildly aggressive environments
• 304 stainless steel case grade for durability and longevity
• Single-scale analog dial with 0 to 15 psi range for low-pressure applications
• 1/4-inch NPT lower-mount connection for direct inline or manifold installation
• Accuracy rated at 2.5 percent of scale across the full range

Compatibility

Designed as an OEM-style or replacement analog pressure gauge for low-pressure plumbing, HVAC, and fluid system applications utilizing standard 1/4-inch NPT lower-mount fittings.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC or mechanical technician. Shut off and depressurize the system completely before removing or installing any gauge. Apply thread sealant or PTFE tape to the NPT threads per standard practice, taking care not to over-torque fittings into gauge ports. Verify the system operating pressure falls within the 0 to 15 psi range before placing the gauge in service.
