Ashcroft 94886 Pressure Gauge 15 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 94886 is an analog pressure gauge designed for accurate pressure monitoring in plumbing, HVAC, and industrial fluid systems. It features a 2.5-inch dial with a 0 to 15 psi range and delivers 1% of scale accuracy, making it suitable for low-pressure applications where reliable readings matter. The stainless steel case provides corrosion resistance in demanding service environments. The lower back mount configuration with a 0.25-inch NPT threaded connection suits panel or pipe installations where the port exits from the rear of the gauge. Licensed plumbers, HVAC technicians, and pipefitters install this gauge as part of system monitoring setups.

The 94886 is well suited for residential and light commercial applications involving water supply lines, compressed air systems, hydronic heating loops, and similar low-pressure fluid circuits. The dry (non-liquid-filled) analog dial provides a straightforward reading without the added complexity of glycerin or silicone fill. Its compact 2.5-inch dial is readable at close range and fits standard gauge panel cutouts. The lower back mount orientation keeps piping connections clean and flush against a panel or manifold surface.

Key Features

• 0 to 15 psi pressure range for low-pressure system monitoring
• 1% of scale accuracy for reliable, repeatable readings
• 2.5-inch analog dial for clear, at-a-glance pressure indication
• Stainless steel case resists corrosion in wet or harsh environments
• Lower back mount with 0.25-inch NPT connection for panel or pipe installation
• Dry gauge construction — no liquid fill for straightforward service

Compatibility

Designed as an OEM-style replacement or new-install gauge for low-pressure plumbing, HVAC, and fluid system applications requiring a 0.25-inch NPT lower back mount analog pressure gauge rated to 15 psi.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system completely before removing or installing any gauge. Apply thread sealant tape or compound to the NPT threads per the applicable plumbing code — do not overtighten, as stainless gauge bodies can crack if excessive torque is applied. Verify the pressure range of the installed gauge matches the operating range of the system before returning it to service.
