Ashcroft 94587XLL Pressure Gauge 2.5 in 0-300 Psi Lower Mount

Product Description

The ASHCROFT 94587XLL is an analog pressure gauge designed for monitoring system pressure in a wide range of industrial, mechanical, and trade service applications. It features a 2.5-inch dial face with a 0 to 300 psi measurement range and delivers 1% of scale accuracy, making it suitable for reliable field readings. The stainless steel case provides corrosion resistance, while the bronze wetted parts suit common fluid and gas media. It mounts from the lower port using a 1/4-inch threaded connection, fitting standard gauge ports on piping, manifolds, and equipment panels. This is a dry, non-liquid-filled gauge. HVAC technicians, plumbers, and industrial service pros install this gauge where a compact, accurate pressure indicator is required.

The ASHCROFT 94587XLL fits residential and light commercial service scenarios including hydronic heating systems, compressed air lines, water supply systems, and refrigeration equipment test points. The lower-mount configuration positions the gauge stem downward, which suits panel-mounted or pipe-tee installations where the dial needs to face the technician. The 1/4-inch lower port is a common thread size found on service valves, manifold fittings, and test ports across multiple system types.

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems requiring a 1/4-inch lower-mount connection and a 0 to 300 psi dry analog gauge with stainless steel case and bronze wetted parts.

Installation Notes

A licensed plumber, HVAC technician, or qualified mechanical contractor should install or replace pressure gauges on pressurized systems. Shut down and depressurize the system fully before removing or installing any gauge. Use appropriate thread sealant on the 1/4-inch NPT connection and avoid over-tightening, which can damage the gauge socket. Follow applicable codes including IPC, IFGC, or local mechanical codes as required for the system type.
