Ashcroft 93013XLL Pressure Gauge 4.5 in Dial 800 Psi Rear Flange

Product Description

The ASHCROFT 93013XLL is an analog pressure gauge designed for accurate pressure monitoring in mechanical and process systems. Featuring a 4.5-inch dial with a 0 to 800 psi range, this gauge delivers 0.5% of scale accuracy, making it suitable for applications where reliable readings are critical. The thermoplastic case provides a lightweight, corrosion-resistant housing. It is configured for rear flange mounting, allowing it to be panel-mounted flush against a surface for clean installations. No liquid fill is used in this gauge. Licensed HVAC technicians, plumbers, and mechanical contractors are the typical installers of this type of gauge.

This pressure gauge is well-suited for residential and light commercial installations where a large, easy-to-read 4.5-inch analog dial is needed. Common applications include boiler systems, compressed air lines, water supply systems, and general-purpose process piping. The rear flange mount configuration is ideal for panel installations or control boards where the gauge face needs to sit flush. The 1/4-inch thread connection is standard for many trade plumbing and HVAC fittings.

Key Features

• 4.5-inch analog dial for clear, at-a-distance pressure readings
• 0 to 800 psi pressure range suitable for a wide range of mechanical applications

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and commercial mechanical systems using a standard 1/4-inch threaded connection with rear flange panel mounting.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Shut off system pressure and depressurize the line completely before removing or installing any pressure gauge. Use appropriate thread sealant on the 1/4-inch connection per local plumbing codes; do not overtighten, as thermoplastic cases may crack under excessive torque. Verify the gauge pressure range matches the system operating pressure before returning the system to service.
