Wika 9833574 Pressure Gauge 0-100 Psi 2-1/2 in Dial Npt Lower

Product Description

The WIKA 9833574 is a liquid-filled industrial pressure gauge designed for monitoring gas and liquid system pressures in demanding trade and industrial applications. The 2-1/2 inch analog dial provides a clear pressure readout across a 0 to 100 psi range, with a 1.5% of scale accuracy rating suitable for general-purpose process and mechanical systems. The stainless steel case and stainless steel wetted parts resist corrosion in wet, chemical-adjacent, and outdoor environments. The polycarbonate lens protects the dial face from impact and moisture ingress. Liquid fill dampens pointer vibration, extending service life and improving readability on systems with pulsating pressure.

This gauge is suited for residential and commercial HVAC systems, plumbing, refrigeration lines, compressed air systems, hydraulic circuits, and general fluid or gas monitoring installations. The 1/4 inch NPT lower mount connection makes it compatible with standard pipe fittings and instrument ports across a wide range of mechanical systems. It installs in both indoor and outdoor environments where consistent, accurate pressure indication is required by service technicians, pipefitters, or HVAC mechanics.

Key Features

• 0 to 100 psi range with 1.5% of scale accuracy for reliable process monitoring
• Liquid-filled case dampens pointer vibration and reduces wear on pulsating systems
• 304 stainless steel case and stainless steel wetted parts for corrosion resistance
• 2-1/2 inch analog dial for clear, at-a-glance pressure readings
• Polycarbonate lens resists impact and moisture
• 1/4 inch NPT lower mount connection fits standard instrument ports and pipe fittings
• Rated for use with gaseous and liquid media

Compatibility

Designed for use with gaseous and liquid media. Suitable as a general-purpose industrial pressure gauge for HVAC, plumbing, compressed air, hydraulic, and process piping systems where a 1/4 inch NPT lower mount connection is specified.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. 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 the system requirements and applicable plumbing or mechanical codes. Do not overtighten the connection, as this can stress the gauge socket and affect accuracy.
