Ashcroft 94919XLL Pressure Gauge 0-30 Psi 3.5in Dial Mnpt

Product Description

The ASHCROFT 94919XLL is an industrial analog pressure gauge designed for accurate pressure monitoring in demanding service environments. It features a 3.5-inch dial with a 0 to 30 psi range and delivers 1% of scale accuracy. The gauge uses a 316 stainless steel Bourdon tube and stainless steel wetted parts throughout, making it well suited for corrosive media and wash-down conditions. The polycarbonate lens resists impact and moisture. A 1/4-inch MNPT center back mount connection simplifies installation in panel or pipe configurations. Licensed HVAC technicians, plumbers, and industrial service professionals install this gauge where reliable pressure indication is required without liquid fill.

This gauge fits residential and commercial applications where a compact, dry-fill pressure gauge is needed on water, air, steam, gas, or compatible fluid systems. The center back mount orientation works well for panel-mounted installations and manifold assemblies. Its stainless steel case and wetted parts make it appropriate for corrosive or high-humidity environments, including chemical processing, water treatment, and HVAC refrigerant or hydronic circuit monitoring where psi values stay within the 0 to 30 range.

Key Features

• 0 to 30 psi analog pressure range with 1% of scale accuracy
• 316 stainless steel Bourdon tube for corrosion resistance with aggressive media
• Stainless steel wetted parts and 304/316 stainless steel case construction
• 3.5-inch dial diameter for clear, at-a-distance readability
• 1/4-inch MNPT center back mount connection for panel and pipe installations
• Polycarbonate lens rated IP54 and IP65/NEMA 4 for moisture and dust protection
• Dry, no-fill design eliminates glycerin or silicone fill compatibility concerns

Compatibility

Designed as an OEM-style replacement or new-install pressure gauge for industrial, HVAC, plumbing, and process applications requiring a 1/4-inch MNPT center back mount gauge with a 0 to 30 psi range and a 3.5-inch dial.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician in accordance with applicable local codes and standards. Shut off system pressure and depressurize the line fully before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape to the MNPT threads per IPC and IFGC guidelines, and do not overtighten, as this can damage the Bourdon tube socket. Verify the pressure range of the system does not exceed 30 psi before placing the gauge in service.
