Wika 9699061 Pressure Gauge 0-100 Psi 4in Dial Npt

Product Description

The WIKA 9699061 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding gaseous and liquid service applications. Featuring a 4-inch analog dial with a 0 to 100 psi range and 1 percent of scale accuracy, this gauge delivers reliable readings in environments where vibration and pressure spikes are common. The stainless steel 304 case and copper alloy wetted parts provide corrosion resistance suited for a wide range of process fluids and gases. A polycarbonate lens protects the dial face. Licensed HVAC technicians, plumbers, and industrial service professionals install this gauge on piping systems, pressure vessels, and mechanical equipment.

This gauge is suited for residential and commercial applications involving gas or liquid service lines where a bottom-connected, lower-mount configuration is required. The 1/4-inch NPT lower-mount connection makes it compatible with standard pipe fittings used throughout plumbing, HVAC, and light industrial piping systems. Liquid filling dampens pointer movement caused by pressure pulsation or system vibration, improving readability and extending service life in high-cycle environments.

Key Features

• 4-inch analog dial with 0 to 100 psi single-scale range
• 1 percent of scale accuracy for reliable field readings
• Liquid-filled case dampens vibration and reduces pointer flutter
• 304 stainless steel case resists corrosion in tough service environments
• Copper alloy wetted parts compatible with a broad range of gases and liquids
• 1/4-inch NPT lower-mount connection fits standard pipe fittings
• Polycarbonate lens provides impact resistance and dial clarity

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for gaseous and liquid service systems requiring a 4-inch dial, 1/4-inch NPT lower-mount connection, and a 0 to 100 psi measurement range.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial pipefitters in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauges. Isolate and fully depressurize the system before removing an existing gauge or installing this unit. Apply an appropriate thread sealant to the NPT threads and hand-tighten before using a wrench, taking care not to overtighten and damage the case or fittings. Do not install in applications with pressure ranges, temperatures, or fluid compatibility requirements outside those stated for this gauge.
