Wika 4253183 Pressure Gauge 0-600 Psi 2.5 in Dial Lower Npt

Product Description

The WIKA 4253183 is a commercial-grade analog pressure gauge designed for monitoring system pressure in a wide range of industrial and mechanical applications. It features a 2.5-inch dial with a 0 to 600 psi single-scale range, making it suitable for higher-pressure service lines. The case is constructed from ABS (Acrylonitrile Butadiene Styrene) for lightweight durability, while the wetted parts are brass for compatibility with common fluid media. Accuracy is rated at 3-2-3 percent of scale. The 1/4-inch NPT lower-mount connection allows for direct pipe-thread installation. No liquid fill is included. Licensed trades and mechanical contractors install this gauge as a standard system-pressure reference instrument.

This gauge fits commercial pressure monitoring applications across HVAC, plumbing, and general mechanical systems. The lower-mount NPT configuration suits panel-mount and in-line pipe installations where a direct bottom connection is required. The 2.5-inch dial face provides clear analog readout in environments where a compact footprint is needed. It is a no-fill gauge, appropriate for non-pulsating, non-vibrating service conditions. Residential and light commercial mechanical systems commonly use this gauge to monitor supply, return, or branch line pressures up to 600 psi.

Key Features

• 0 to 600 psi single-scale pressure range for higher-pressure service lines
• 2.5-inch analog dial for clear, direct-read pressure indication
• 1/4-inch NPT lower-mount connection for standard pipe-thread installation
• Brass wetted parts for compatibility with common fluid media
• ABS case construction for lightweight, corrosion-resistant housing
• 3-2-3 percent of scale accuracy meets commercial gauge standards
• No-fill design suited for stable, non-pulsating pressure service

Compatibility

Designed as an OEM-style commercial pressure gauge for use in mechanical systems requiring a 1/4-inch NPT lower-mount connection and a 0 to 600 psi measurement range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Shut off system pressure and depressurize the line fully before removing or installing any gauge. Apply thread sealant or PTFE tape to the NPT threads per standard trade practice and applicable IPC or IFGC guidelines. Do not over-tighten the brass connection; use a properly sized wrench on the gauge body, not the dial case.
