Ashcroft 94597XLL Pressure Gauge 3.5 in 0-60 Psi Lower Mount

Product Description

The ASHCROFT 94597XLL is a dry, analog pressure gauge designed for accurate pressure monitoring across a wide range of plumbing, HVAC, and industrial service applications. It features a 3.5-inch dial for easy readout, a lower-mount 0.25-inch NPT connection, and a measurement range of 0 to 60 psi. Accuracy is rated at 1% of scale, meeting the demands of trade professionals who need reliable, repeatable readings. The stainless steel case resists corrosion in demanding environments, while bronze wetted parts provide compatibility with a broad range of media. This gauge is not liquid-filled, making it well suited for stable, non-pulsating pressure service.

This gauge is commonly installed in residential and light commercial systems where pressure monitoring is required at pump outlets, filter housings, pressure tanks, boiler systems, and similar low-to-mid-range pressure points. The lower-mount configuration allows for direct in-line installation on threaded pipe or manifold ports. HVAC technicians, plumbers, and pipefitters routinely specify this type of gauge for system commissioning, diagnostic checks, and permanent monitoring installations. The 3.5-inch dial face provides clear visibility in panel or wall-mounted applications.

Key Features

• 0 to 60 psi range suitable for low-to-mid-range pressure systems
• 1% of scale accuracy for reliable, repeatable measurements
• Lower-mount 0.25-inch NPT connection for direct in-line installation
• Stainless steel case provides corrosion resistance in harsh environments
• Bronze wetted parts compatible with a broad range of service media
• Dry gauge design with no liquid fill, suited for stable pressure service

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and light commercial plumbing, HVAC, and general-purpose piping systems requiring a lower-mount, 0.25-inch NPT, dry analog gauge in the 0 to 60 psi range.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply appropriate thread sealant or PTFE tape to the NPT threads before threading the gauge into the port; do not overtighten, as this can damage the brass socket or threads. For permanent monitoring installations, verify the gauge orientation provides a clear line of sight to the dial face from the service position.
