Wika 9325107 Pressure Gauge 0-7500 Psi 2.5in Dial Lower Npt

Product Description

The WIKA 9325107 is a glycerine-filled industrial pressure gauge designed for demanding fluid and gas pressure measurement applications. The gauge features a 2.5-inch analog dial with a single scale reading from 0 to 7,500 psi, providing clear, accurate readings across a wide pressure range. Wetted parts are copper alloy, and the case is brass construction. Accuracy is rated at 1.5 percent of full scale. A lower-mount, 1/4-inch NPT connection makes this gauge suitable for direct pipe or manifold installation. Licensed HVAC, plumbing, and mechanical contractors commonly specify gauges of this type for system pressure monitoring and commissioning work.

This gauge is suited for industrial, commercial, and heavy mechanical applications where high-pressure monitoring is required. The glycerine fill dampens needle vibration in systems with pulsating flow or pressure spikes, maintaining readability and protecting internal movement. Lower-mount NPT threading allows installation directly into a piping tee, manifold port, or pressure tap without additional adapters in most standard configurations. Typical use cases include hydraulic systems, compressed air lines, water systems, and other fluid-handling circuits operating up to 7,500 psi.

Key Features

• 0 to 7,500 psi single-scale analog dial for wide-range high-pressure measurement
• Glycerine-filled case dampens needle vibration from pressure pulsation
• 1.5 percent of full-scale accuracy for reliable readings
• Brass case with copper alloy wetted parts for broad fluid compatibility
• 1/4-inch NPT lower-mount connection for direct pipe or manifold installation
• Acrylic lens for clear dial visibility

Compatibility

Designed as an OEM-style replacement or new-installation gauge for industrial, mechanical, and plumbing pressure monitoring applications requiring a 1/4-inch NPT lower-mount connection and a 0 to 7,500 psi range.

Installation Notes

Installation should be performed by a qualified plumbing or mechanical technician in accordance with applicable local codes and the IFGC or IPC as relevant to the system type. Depressurize and isolate the system completely before removing an existing gauge or threading in a new one. Apply an appropriate thread sealant to the NPT threads and tighten to snug without overtorquing the brass fitting. Verify zero reading before returning the system to service.
