Ashcroft 95587XLL Pressure Gauge 4.5 in Dial 0-30 Psi Rear Flange

Product Description

The ASHCROFT 95587XLL is an analog pressure gauge designed for accurate pressure monitoring in plumbing, HVAC, and industrial process applications. It features a 4.5-inch dial for clear readability at a distance and a 0 to 30 PSI range suitable for low-pressure systems. The gauge carries a 0.5 percent of scale accuracy rating, making it appropriate for installations where precise pressure readings are required. The thermoplastic case offers resistance to moisture and corrosion in light-duty environments. The rear flange mount configuration allows for panel or bulkhead installation. Licensed plumbers, HVAC technicians, and mechanical contractors are the typical installers.

This gauge is well suited for residential and light commercial applications where low-pressure monitoring is needed. Common install scenarios include domestic water supply lines, boiler systems, compressed air manifolds, and hydronic heating circuits operating within the 0 to 30 PSI range. The 4.5-inch dial diameter makes it a practical choice for control panels and equipment rooms where readability from across a work area is a priority. The no-fill design means no liquid damping is present, which keeps maintenance simple in low-vibration environments.

Key Features

• 4.5-inch analog dial for high-visibility pressure readings
• 0 to 30 PSI pressure range for low-pressure system monitoring
• 0.5 percent of scale accuracy for reliable measurement
• Rear flange mount for panel or bulkhead installation
• Thermoplastic case for corrosion resistance in light-duty service
• No-fill design simplifies maintenance in low-vibration environments

Compatibility

Designed as an OEM-style replacement or new-installation analog pressure gauge for low-pressure plumbing, HVAC, and hydronic systems requiring a rear flange mount configuration with a 4.5-inch dial.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and relieve all residual pressure in the line before removing or installing the gauge. Apply thread sealant or PTFE tape to the 0.5-inch male threads per local plumbing code requirements. Do not over-torque the threaded connection, as thermoplastic fittings and gauge bodies can crack under excessive force.
