Ashcroft 94337XLL Pressure Gauge 0-60 Psi 3.5 in Lower Mount

Product Description

The ASHCROFT 94337XLL is an industrial-grade analog pressure gauge designed for accurate pressure monitoring in demanding process and mechanical applications. It features a 3.5-inch dial with a 0 to 60 psi range and delivers 1 percent of scale accuracy. The wetted parts are 316 stainless steel and the case is 304/316 stainless steel, making it well suited for corrosive or harsh environments. A polycarbonate lens provides impact resistance while maintaining dial readability. The gauge is not liquid filled and uses a Bourdon tube measuring element. Licensed HVAC technicians, plumbers, and industrial maintenance professionals are the typical installers.

This gauge is built for industrial pressure measurement in plumbing, HVAC, process piping, and general mechanical systems. The lower mount configuration with a 0.25-inch MNPT connection allows direct installation into pipe fittings, manifolds, or panel-mounted ports from the bottom of the gauge body. Its stainless steel construction makes it appropriate for both wet and dry service lines where corrosion resistance is a priority. The analog dial provides at-a-glance readings without the need for external power or signal wiring.

Key Features

• 0 to 60 psi pressure range with 1 percent of scale accuracy
• 3.5-inch analog dial for clear, direct-read pressure monitoring
• 316 stainless steel Bourdon tube and wetted parts for corrosion resistance
• 304/316 stainless steel case for durability in industrial environments
• Lower mount, 0.25-inch MNPT connection for standard pipe thread installation
• Polycarbonate lens rated IP54 and IP65/NEMA 4 for moisture and dust protection
• No liquid fill — dry gauge suitable for non-pulsating applications

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for systems using a lower-mount 0.25-inch MNPT connection with a 0 to 60 psi operating range.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified industrial maintenance personnel. Depressurize and isolate the line completely before removing an existing gauge or installing this unit. Apply thread sealant tape or compound to the MNPT threads per applicable IPC or IFGC guidelines, and avoid over-tightening, which can damage the gauge socket. Do not install on lines with severe pulsation or vibration without an appropriate snubber or isolator.
