Ashcroft 94588XLL Pressure Gauge 0-300 Psi 2.5in Lower Mount

Product Description

The ASHCROFT 94588XLL is an analog industrial pressure gauge designed for monitoring system pressure in a wide range of commercial and industrial applications. The gauge features a 2.5-inch dial with a 0 to 300 psi range and delivers 1% of scale accuracy, making it suitable for process monitoring where reliable readings matter. The 304/316 stainless steel case provides corrosion resistance in harsh environments, while the polycarbonate lens protects the dial face. Bronze wetted parts and a 316 stainless steel Bourdon tube handle the fluid contact side of the measurement. The lower-mount, 1/4-inch MNPT connection allows direct installation into threaded ports on pipework, manifolds, or equipment panels. This gauge ships as a dry, no-fill unit.

This gauge is suited for installation in industrial process systems, HVAC hydronic circuits, compressed air lines, water treatment equipment, and general plumbing applications where pressures up to 300 psi must be monitored. The lower-mount configuration positions the connection at the six o'clock position, making it a common choice for panel-mount or pipe-tee installations. Licensed plumbers, pipefitters, and HVAC mechanical contractors are the typical installers for this type of instrumentation.

• Certified to CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as a direct-install replacement or new-installation industrial pressure gauge for any threaded 1/4-inch MNPT port requiring a 0 to 300 psi dry-service analog gauge with a lower-mount configuration.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Isolate and depressurize the system completely before removing an existing gauge or threading in a new one. Apply thread sealant or PTFE tape to the male threads per local plumbing codes before installation. Do not use the gauge body or dial as leverage when tightening; use a wrench on the hex of the connection fitting only.
