Ashcroft 94328XLL Pressure Gauge 0-100 Psi 2.5 in Lower Mount

Product Description

The ASHCROFT 94328XLL is an industrial-grade analog pressure gauge designed for accurate pressure measurement in demanding service environments. It features a 2.5-inch dial with a 0 to 100 psi range and delivers 1% of scale accuracy across that range. The wetted parts are 316 stainless steel, and the case is 304/316 stainless steel, making it well suited for corrosive or washdown environments. A polycarbonate lens protects the dial face. This is a dry (no liquid fill) gauge with a lower-mount 1/4-inch MNPT connection. Licensed plumbers, HVAC technicians, and industrial maintenance technicians typically install this gauge in piping, pressure systems, and process equipment.

The 94328XLL is appropriate for residential, commercial, and light industrial applications where reliable pressure indication is needed. Common install scenarios include water supply lines, compressed air systems, hydronic heating systems, and process piping where corrosion resistance is a requirement. The lower-mount configuration allows direct inline installation on threaded pipe or manifold ports. Its stainless steel construction and sealed ratings make it a practical choice for outdoor or wet-location installations as well.

Key Features

• 1% of scale accuracy across the full 0 to 100 psi range
• 316 stainless steel Bourdon tube and wetted parts for corrosion resistance
• 304/316 stainless steel case rated for harsh and washdown environments
• Polycarbonate lens for impact and chemical resistance
• Dry gauge construction with no liquid fill — no risk of fluid contamination
• Meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for any threaded 1/4-inch MNPT port requiring a lower-mount analog gauge in the 0 to 100 psi range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or qualified maintenance technician. Isolate and depressurize the system fully before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape to the MNPT threads per local code requirements — do not over-tighten, as stainless-to-steel connections can gall. Verify the system pressure range does not exceed 100 psi steady-state service before placing the gauge in service.
