Ashcroft 94231XLL Pressure Gauge 0-1500 Psi 2.5 in Dial

Product Description

The ASHCROFT 94231XLL is an industrial analog pressure gauge designed for accurate pressure measurement in demanding service environments. It features a 2.5-inch dial with a 0 to 1500 psi range and delivers 1% of scale accuracy. The Bourdon tube is 316 stainless steel, the case is 304/316 stainless steel, and all wetted parts are stainless steel, making this gauge suitable for corrosive media and harsh conditions. It mounts from the lower port using a 1/4-inch MNPT male connection and ships dry with no liquid fill. Licensed HVAC technicians, plumbers, pipefitters, and mechanical contractors install this gauge as part of pressure monitoring assemblies on process lines, HVAC systems, and plumbing systems.

This gauge is sized for applications where a compact 2.5-inch dial provides sufficient readability in panel, pipe, or manifold installations. The stainless steel wetted parts suit water, steam, oil, gas, and mild chemical service. The lower-mount configuration fits standard direct-mount installations on threaded pipe tees, manifolds, and test ports. No liquid fill means straightforward installation without concern for fluid leakage from the case. Typical installations include mechanical rooms, boiler rooms, chiller piping, compressed air systems, and industrial process lines.

Key Features

• 0 to 1500 psi pressure range with 1% of scale accuracy
• 316 stainless steel Bourdon tube for corrosion resistance with aggressive media
• 304/316 stainless steel case for durability in wet or corrosive environments
• All stainless steel wetted parts minimize contamination risk
• 1/4-inch MNPT lower-mount connection for direct pipe installation
• Polycarbonate lens with IP54 and IP65/NEMA 4 enclosure ratings
• Dry gauge, no liquid fill — no special handling required during installation

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for systems requiring a 1/4-inch MNPT lower-mount, 2.5-inch dial gauge rated to 1500 psi. Complies with CRN, PED, RoHS, IP54, and IP65/NEMA 4 standards. Part of the Ashcroft 1009 Series.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Isolate and depressurize the system completely before removing any existing gauge or fittings. Apply appropriate thread sealant to the MNPT threads and torque by hand to snug fit before using a wrench — do not overtighten, as this can damage the gauge socket. Verify pressure range is appropriate for the system before returning the line to service.
