Wika 9767045 Pressure Gauge 0-30 Psi 2.5 in Dial Lower Npt

Product Description

The WIKA 9767045 is a liquid-filled industrial pressure gauge designed for monitoring gaseous and liquid media in a wide range of mechanical, HVAC, plumbing, and process applications. The gauge features a 2.5-inch analog dial with a 0 to 30 psi range and a 1/4-inch NPT lower-mount connection. Accuracy is rated at 1.5 percent of full scale. The stainless steel 304 case and copper alloy wetted parts provide durability in wet or corrosive service environments. A polycarbonate lens protects the dial face from impact and moisture. Licensed trades and mechanical contractors install this gauge during system commissioning or as a replacement on existing equipment.

This gauge is suited for residential and light commercial systems where low-pressure monitoring is required. Typical applications include water supply lines, HVAC hydronic circuits, compressed air systems, and fluid process lines. The liquid-filled design dampens needle vibration, making it easier to read in systems with pulsating pressure. The lower-mount NPT connection fits standard pipe fittings used throughout plumbing and HVAC installations.

Key Features

• 0 to 30 psi pressure range with single analog scale
• 2.5-inch dial for clear reading at typical service distances
• 1.5 percent of full-scale accuracy
• Liquid-filled design reduces needle flutter in pulsating systems
• 304 stainless steel case resists corrosion in wet environments
• Copper alloy wetted parts compatible with water, oil, and many gaseous media
• Polycarbonate lens provides impact and moisture resistance

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems requiring a 1/4-inch NPT lower-mount connection with a 0 to 30 psi range, compatible with gaseous and liquid media service.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Shut off system pressure and relieve all residual pressure before removing or installing any gauge. Apply thread sealant appropriate for the media type to the NPT threads before installation. Do not overtighten the connection, as damage to the brass socket or pipe fitting threads may result in leaks.
