Ashcroft 94326XLL Pressure Gauge 0-30 Psi 2.5 in Dial

Product Description

The ASHCROFT 94326XLL is an analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and light industrial applications. It features a 2.5-inch dial with a 0 to 30 psi range and delivers 1% of scale accuracy, making it a reliable choice for process monitoring where precise readings matter. The stainless steel case and stainless steel wetted parts provide corrosion resistance in demanding environments. The lower-mount, 1/4-inch threaded connection simplifies installation on pipes, manifolds, and test ports. This gauge ships dry with no liquid fill.

This gauge is well suited for residential and light commercial plumbing systems, hydronic heating loops, compressed air lines, and HVAC refrigerant-side test setups where pressures stay within the 0 to 30 psi range. The lower-mount configuration positions the dial face-forward when the gauge is threaded directly into a bottom port, making it easy to read at the point of installation. It is typically installed by licensed plumbers, HVAC technicians, or pipefitters during system commissioning, service calls, or pressure testing.

Key Features

• 0 to 30 psi pressure range suitable for low-pressure plumbing and HVAC applications
• 1% of scale accuracy for reliable pressure monitoring
• 2.5-inch analog dial for clear, direct reading at the gauge location
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• Lower-mount, 1/4-inch threaded connection for straightforward installation on bottom-port fittings
• Dry gauge with no liquid fill, reducing maintenance considerations

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for low-pressure plumbing, hydronic, and HVAC systems requiring a 1/4-inch lower-mount connection and a 0 to 30 psi range.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician. Depressurize and isolate the system before removing any existing gauge or fitting. Apply thread sealant tape or pipe dope to the male threads per local code requirements before threading the gauge into the port. Do not over-tighten; use a wrench on the gauge hex, not the dial case, to avoid damaging the bourdon tube or case seal.
