Ashcroft 94234XLL Pressure Gauge 0-5000 Psi 2.5in Dial

Product Description

The ASHCROFT 94234XLL is an industrial analog pressure gauge designed to measure system pressure from 0 to 5000 psi. It features a 2.5-inch dial with a 304/316 stainless steel case and stainless steel wetted parts, making it well suited for demanding fluid and gas service. The Bourdon tube is 316 stainless steel. Connection is via a 1/4-inch MNPT lower-mount fitting. Accuracy is rated at 1 percent of full scale. The lens is polycarbonate. This gauge is not liquid-filled. It is installed by licensed plumbers, HVAC technicians, pipefitters, and industrial maintenance technicians in applications requiring reliable local pressure indication.

This gauge is used in residential and commercial HVAC, plumbing, hydraulic, and industrial process systems where a durable, corrosion-resistant pressure gauge is required. The lower-mount configuration fits standard panel and pipe installations. The stainless steel wetted parts make it appropriate for mildly corrosive media, water, steam, oil, and air service. The no-fill design keeps installation straightforward and eliminates concerns about fill-fluid compatibility with system media.

Key Features

• 0 to 5000 psi pressure range with 1 percent of scale accuracy

• 316 stainless steel Bourdon tube and stainless steel wetted parts
• 1/4-inch MNPT lower-mount connection for standard pipe thread installations
• 2.5-inch analog dial for clear local readout
• Polycarbonate lens; no liquid fill required
• Rated to IP54 and IP65/NEMA 4 ingress protection standards

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for systems requiring a 1/4-inch MNPT lower-mount connection and a 0 to 5000 psi range. Meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician following applicable local codes and ASME B40.100 gauge installation guidelines. Depressurize and isolate the system completely before removing or installing any pressure gauge. Apply thread sealant to the MNPT threads per the sealant manufacturer instructions; do not over-tighten, as this can damage the socket or case. Verify the system pressure range does not exceed the gauge maximum rating before placing the system back into service.
