Ashcroft 94331XLL Pressure Gauge 0-300 Psi 2.5 in Dial

Product Description

The ASHCROFT 94331XLL is an analog pressure gauge built for trade and industrial applications where accurate, reliable pressure readings are required. The gauge features a 2.5-inch dial diameter, a lower-mount 0.25-inch threaded connection, and a stainless steel case with stainless steel wetted parts. It covers a pressure range of 0 to 300 psi with 1 percent of scale accuracy. The all-stainless wetted parts make it suitable for service with mildly corrosive media or where hygiene and corrosion resistance matter. Licensed plumbers, HVAC technicians, and industrial service techs are the primary installers. This is a dry-fill gauge with no internal liquid damping.

The 94331XLL is suited for residential and light commercial plumbing, HVAC refrigerant and water systems, compressed air lines, and hydraulic test setups where pressures fall within the 0 to 300 psi range. The lower-mount configuration positions the process connection at the six-o-clock position on the gauge body, making it compatible with direct pipe nipple or manifold installations where the gauge mounts upright. The compact 2.5-inch dial is a common panel and instrument-line size across a wide range of service applications.

Key Features

• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 0 to 300 psi pressure range with 1 percent of scale accuracy
• 2.5-inch analog dial for clear, direct reading
• Lower-mount connection simplifies inline and panel installations
• Dry-fill design — no internal liquid filler
• 0.25-inch threaded process connection

Compatibility

Designed as an OEM-style or direct replacement pressure gauge for plumbing, HVAC, compressed air, and light industrial systems requiring a 2.5-inch lower-mount gauge with a 0.25-inch threaded connection and a 0 to 300 psi range.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and relieve system pressure completely before removing or installing any gauge. Apply thread sealant tape or compound appropriate for the service medium to the male threads, and tighten using a wrench on the hex fitting — do not use the gauge case for leverage. Follow applicable codes including IPC, IFGC, or NEC as relevant to the system being serviced.
