Kodiak Controls EA14A Gauge

The Kodiak Controls EA14A Gauge is a professional-grade 4 1/2" contractor gauge designed specifically for the rigorous demands of HVACR and mechanical contracting. Featuring a 0-30 PSI pressure range, this instrument utilizes a phosphor bronze Bourdon tube and a durable brass socket to deliver a high-accuracy measurement of ±1% full scale (ASME B40.100 Grade 1A). The 4.5-inch dial provides a wide 270° arc with bold black graduations on a white background, ensuring high visibility in low-light mechanical rooms. Built with a corrosion-resistant stainless steel case and ring, this dry-case gauge is suitable for air, water, oil, and gas applications where the media is non-corrosive to copper alloys. The 1/4" NPT lower mount connection simplifies installation on manifolds and headers. For steam service, a siphon must be installed to protect the internal brass movement. A front-accessible recalibrator screw allows for field adjustments, maintaining peak performance across the entire 30 lb pressure scale.

• ASME Grade 1A Accuracy: Delivers precise ±1% full-scale readings, critical for balancing hydronic systems and checking low-pressure boiler lines.
• Stainless Steel Protection: The 304 stainless steel case stands up to humid environments and corrosive atmospheres common in industrial settings.
• Enhanced Readability: The 4 1/2 inch dial face offers significantly better resolution than standard 2-inch utility gauges for identifying subtle pressure drops.
• Field Serviceable: Includes an integrated zero-adjustment screw on the dial face, allowing technicians to re-zero the pointer without dismantling the case.
• Versatile Media Compatibility: Engineered for HVACR contractors working with air, water, or oil, providing a reliable brass/bronze wetted part construction.

Can this gauge be used for steam applications?
Yes, the Kodiak EA14A is suitable for steam provided a siphon (pigtail) is installed between the gauge and the line to prevent live steam from reaching the bronze Bourdon tube.

Is this gauge suitable for outdoor installation?
The stainless steel case provides excellent corrosion resistance, but as a dry case gauge, it is best suited for protected environments. For high-vibration outdoor areas, a liquid-filled model may be preferred.

What is the connection size?
This model features a standard 1/4" NPT male thread with a lower mount (bottom) orientation for easy vertical installation.
